How to clean a chimney. How to clear clogged pipes at home: the best cleaning products and methods. How to understand that the chimney is clogged

Cleaning the chimney is necessary for any pipe, since during operation it accumulates a large number of carbon deposits and products that are not able to burn completely. Therefore, cleaning chimneys is important for a stove or fireplace, since constant settling harmful substances on their basis leads to clogging of the pipe, which will cause a decrease in traction due to a change in the size of the lumen. If you don't use a chimney cleaner promptly, in the worst case scenario, your stove could catch fire. Or the smoke generated during the combustion process will constantly enter the room. The only solution to this problem is chimney cleaning, which is carried out before the heating season or immediately after it. So, how to clean a chimney from soot, soot and soot, and how often should this manipulation be carried out?

This method is the most traditional - it is carried out from the roof using special device, which is shaped like a brush. To do this, a projectile of a certain mass is carefully placed into the pipe. A cable must be attached to its center. A dense brush is attached just above the core, which quickly and efficiently removes soot. In this case, the core is necessary in order to weigh down the entire structure, as well as to check the permeability and internal diameter of the pipes.

It is important to note that when cleaning the chimney from soot and deposits, they can fly into your face, so you need to protect it before work. This happens especially often if the stove has good draft. In addition, it is also important to protect the face and respiratory tract, as well as tie yourself to the pipe, because during a sudden release of garbage into the face, a person unconsciously makes a sudden movement. And this, as a rule, ends in failure.

It’s quite easy to make a brush for cleaning a chimney with your own hands, the main thing is to find and properly secure the load. It must be even and round so that the object does not tip to one side - then it will be quite difficult to achieve high-quality cleaning. However, when searching for a projectile, you do not need to use weights or heavy pieces of iron, since sooner or later they will stand up in the chimney, and they can only be removed by cutting out a fragment of the pipe. You can also make your own brush from metal-based bristles - this is usually the easiest part of a pipe cleaner to make.

If the pipe is too high and cannot be reached from the roof, in this case the chimney pipes are cleaned from below.

In this case, you need to follow several steps:

1. Remove the glass made of metal from the bottom of the chimney. To do this, you need to unscrew its base and then carefully remove the glass.
2. Then a flexible hose is inserted into the pipe, which cleans the pipe. If desired, this hose can be replaced with a wire that cannot break quickly.

If there is no such glass at the chimney, it is possible to clean the pipe through the firebox, but this is quite difficult.

If the base of the pipe is made of metal, cleaning the pipe with a brush will not be enough, since a significant part of the carbon will remain on its walls. In this case, a small piece of dense fabric is attached to a wire or rod, which ensures excellent cleaning of the chimney.

How to make a chimney brush with your own hands? It can be done using polypropylene pipes, which should be cut into 1.5 meter pieces. At one end of the pipes you need to install fittings, on the basis of which there will be a thread. After this, a brush designed for working with an angle grinder is attached to them. Before cleaning, such a brush must be fluffed up - this is done with pliers or pliers. It’s also easy to make a brush from plastic bottle.

How to clean a chimney pipe using chemical methods

You can clean the chimney of soot and deposits using any chemical means that will reduce the amount of mechanical cleaning of the chimney. They can be used for pipes made of any metal.

It is important to note that if you have not cleaned your chimney for a long time, any chemical composition one model can completely clog it.

Therefore, it is recommended to use several means. If the stove pipe is straight, you should note that carbon deposits will fall off it within 2 days after cleaning. If the chimney is curved, when cleaning it is important to clean all windows designed for quality cleaning.

In order not to use certain tools to clean the chimney, you can clean the chimney of soot using folk remedies. For example, our ancestors sometimes poured a little salt into the firewood. This method allows you to quickly say goodbye to soot and other dirt, and it will not leave the pipe through it. bottom part, but through the top, namely flying away after peeling. In addition, such cleaning is obtained with high quality if salt is poured into very hot firewood. After a kilogram of salt is poured into the oven, you need to heat it for another 1-1.5 hours. All soot and deposits will quickly burn in the chimney, so you don’t have to clean it with a brush or brush.

Starch is also actively used as a cleaning agent. As in the previous case, the firewood needs to be heated well, and then pour starch or potato peelings onto it. You can use chopped potatoes if you wish. This dry cleaning differs from the previous one in that all the dirt will fall down and not fly out through the chimney.

How to clean an aluminum chimney? Even ordinary cans can clean a chimney if the wood burns very well. In this case, this container will burn out in just 5-7 minutes. If the jar only darkens, there will be no effect from cleaning.

How to clean a chimney with store-bought chemicals? To do this you need to buy store product, which is currently sold in briquette or log form. For example, a briquette contains powder, which also contains a measuring spoon. Such products must be used strictly according to the instructions, without exceeding the indicated dose (to do this, you should carefully read the instructions for the composition).

Currently, there are a lot of means that will remove carbon deposits and soot from the chimney. For example, it could be a Cheerful Chimney Sweep, a Pro Chimney Sweep, Hansa, or Kominichek. In order for such compositions to properly perform their function, you need to pour 1 or 2 spoons into the flame, then heat the stove for another 30-60 minutes. These types of powders do an excellent job and also efficiently remove carbon deposits and other contaminants. It is important to note that it is recommended to use them no more than once every six months.

Also, when cleaning the stove, you can use compositions in the form of a log, which is placed in the flame and begins to slowly burn. In this case, chemical components and mixtures are added directly to the log. It is important to note that this device should be used strictly according to the instructions, otherwise you will not be able to achieve a positive result from cleaning. The name of the most famous logs for cleaning chimneys is Sazhinet, Chimney Sweep.

Using any chemicals, you will be able to:

• Clean the chimney less often;
• do not waste time cleaning with a brush or other devices;
• carry out mechanical cleaning less often, which is not only long, but also difficult;
• do not inhale gases that are in one composition or another;
• do not clean the inside of the oven as this may result in chemical components the soot burns, becomes soft and quickly leaves the pipe through the upper hole;
• do not clean the chimney for longer, since the chemicals perfectly remove any carbon deposits, even those that have not been cleaned in the chimney for a long time.

After using chemicals, the cleaned pipe will not emit unpleasant odor, which means that this manipulation will take place quickly, safely and quite efficiently, and the pipes will remain clean for a long time.

If there was no benefit from one or another cleaning composition or you do not want to waste time using folk or store-bought compositions, you can try cleaning the pipe using thermal methods. They are based on the fact that soot and soot are high-calorie hot substances. However, the heat wave that forms in the furnace is not enough for them to burn completely. The fact is that soot burns out completely at a temperature of 1100 degrees. And almost all houses, roofs and materials from which pipes are made simply cannot withstand such a thermal shock.

In addition, the stove design cannot absorb too much soot, so over time it begins to gradually clog the base of the chimney. However, if it is completely clogged, it is dangerous to use thermal methods, since when the soot is heated strongly, it makes a strong sound, similar to an explosion. Currently, there have been cases when ovens literally fell apart as a result of high loads on them, so this cleaning method is not always reliable and safe.

To cause the appearance high temperature in the stove, you need to use aspen wood.

This is done as follows:

• several dry sticks are placed in the oven, after which they are set on fire (it is advisable to do this without foreign objects, which include paper, newspapers, and so on);
• Every 1-2 minutes, firewood is added until the oven is very hot;
• if there is not enough firewood, you can try using other firewood, not just aspen;
• 5-10 minutes after the pipe has completely warmed up, characteristic pops will appear, which will let you know that the soot has begun the combustion process.

These methods should be used extremely carefully so as not to damage the stove or cause destruction of the chimney. It is advisable to carry out thermal cleaning methods in the morning, so that during the day the house has time to ventilate from the unpleasant odor that sometimes appears during the burning of soot and soot.

When choosing a method for cleaning a chimney, you need to take into account all the features of the chimney, the quality of the stove, the material from which the pipe is made, as well as the duration of the previous cleaning - only in this case will it be possible to clean the chimney efficiently and quickly, as well as carry out this manipulation in the shortest possible time.

Residents of private houses heat stoves and fireplaces during the cold season. During the operation of heating appliances, soot accumulates in chimneys. This makes it difficult for smoke to escape, creating a risk of fire in the room and intoxication of the people living in it.

From burning and black soot in the chimney, you need to know how to clean chimneys in the stove using folk remedies. Many people think about solving the problem when smoke is already coming into the room.

The need to clean the chimney

In winter, stoves and fireplaces are lit almost continuously. Over time, cravings get worse. Soot settles on the walls of the chimney. It narrows the existing opening and does not allow smoke to fully pass through and enter the room.

Due to the high temperature in the chimney, accumulated soot can catch fire. This leads to its destruction. Sparks flying from the pipe become a source of fire. Or lead to carbon monoxide poisoning. The owners have a question about how to clean the chimney pipe.

The condition of the pipe must be inspected at least twice a year. Before the beginning heating season and after it.

When to clean

Whether the chimney needs cleaning can be determined by eye. First of all, pay attention to the color of the smoke. If the stove is intact and the chimney is clean, then clouds of light gray or white. Dense black smoke signals the need for preventive measures: soot has accumulated in the chimney.

The color of the flame in the firebox also matters. If the light orange tint changes to dark orange, the structure needs to be cleaned.

Soot deposits

Smoke contains mechanical particles. They stain the surface of the canal. Soot accumulates in the pipe and a black coating appears. Deposits harden as a result of saturation with water vapor. The pipe is clogged. Channel bends, transitions, and the surfaces of brick pipes are covered with a layer of soot.

The volume of deposits depends on various factors:

• The stove or fireplace is not installed correctly.
• The technology for laying the product components is broken.
• Construction materials are of poor quality. Cracks appear on the surface of the chimney.
• The chimney system is cluttered with debris.
• There is no umbrella on the pipe. Depending on the humidity, type of fuel and features of the fireplace, the rate of deposit accumulation depends.

Traditional methods of cleansing

The quality of operation of a stove or fireplace is affected by the layer of soot on the walls of the chimney pipe. The fumes enter the living space, and the soot deposited on the chimney ignites. Troubles can be avoided if you do not forget to clean the chimneys of stoves and fireplaces from soot.

DIY cleaning methods:

If the soot does not come off well, you can tap the chimney wall with a stick. But it is not always possible to clean the chimney efficiently using potato peelings. This is only a means to help soften the soot so that it lags behind the pipe walls. After peeling potatoes, it is advisable to carry out mechanical peeling.

A good way is to burn aspen wood in a stove. But it's not entirely safe. The soot catches fire and flakes out of the chimney. They cover the roof and area around the building. Therefore, you first need to make sure whether the roof can withstand such a load and inspect the condition of the chimney pipe.

If there is a lot of soot in the pipe, it is better to use another, safer method.

Tools and materials

First you need to prepare your tools. In order to clean the chimney, you will need:

The core is used not only to remove blockages. To make cleaning effective, you can use it to make the brush and brush heavier.

The length of the device can be changed by connecting the elements using carabiners and a cable.

Mechanical cleaning

This method is also popular. In the old days, chimney sweeps used cannonballs secured by cable. They broke through dense soot growths. Brushes of various shapes and scrapers were also used.

Cleaning process:

Sometimes the pipe is high and you can’t get to it from the roof. Then clean from below.

If the chimney is metal and there is a cleaning glass, it is unscrewed and a brush on a bendable rod is inserted into the pipe. If it is not there, clean it through the cleaning hole.

Cleaning the chimney through the firebox is time-consuming and inconvenient. Cleaning a metal pipe with a brush is not effective. Soot remains on the walls. In this case, the brush is replaced with a rag.

Homemade brush

A cleaning brush is made from polypropylene pipes. The pipes are cut one and a half meters long. Threaded fittings are placed at their ends. A metal brush for an angle grinder is attached to one of the fittings. The wire is fluffed onto the brushes using pliers or pliers. This creates a telescopic cleaning rod for the chimney.

Small mechanization can be used. The method consists in placing an attachment on the impeller of the chainsaw, which allows for forced ventilation of the pipe.

This method is extreme, it can be used in agreement with neighbors

Special store preparations

There are various cleaners sold in stores. You can buy them in the form of powder, logs or briquettes. Please read the instructions before purchasing. Preparations can be for fireplaces, sauna or closed heating stoves.

Popular means:

Work safety

Work on cleaning the chimney from soot requires compliance with safety precautions in order to avoid accidents.

Safe chimney cleaning:

• Do not clean the pipe from soot in wet weather, with high humidity, in strong winds.
• You cannot climb onto the roof without a safety belt. You can tie the belt with a strong rope.
• It is prohibited to take alcohol or drugs that slow down the reaction before work. The measures taken will help avoid risks when cleaning the chimney.

Professional chimney sweeps know how to clean soot from a chimney pipe. You can use their advice. They will help increase the life of the fireplace.

Cleaning the chimney of a sauna stove

The Russian bathhouse is always associated with wet steam and a stove. There is chimney which needs to be cleaned periodically.

If you don’t do this, the sauna will heat poorly and there will be no traction. A fire may occur.

Causes of clogged chimney of a sauna stove:

• Condensate.
• Soot and soot.
• Trapped foreign objects.

To quickly and easily clean the chimney with your own hands, you can use special briquettes with chemicals. When burned, they destroy the soot. The briquettes are burned in a furnace and within a day the dirt will fall into the firebox itself. But it is not recommended to use such preparations for cleaning bath pipes.

You can use a special brush or ruff. They are hung on a weight and lowered into the pipe.

Sometimes the smoke comes back when lighting. There is probably a foreign object in the chimney. It could be a masonry brick or a bird's nest that fell from nearby trees.

It is more difficult to get rid of such a blockage. You can take a stick or long pole and try to push the object inside. At the end of the stick, a hook is made from a nail to hook the object. Good result provides heating of the stove with aspen wood.

It is advisable to make a removable visor on the bath pipe. Snow and rainwater will be prevented from entering the chimney.

Attention, TODAY only!

The passage of smoke channels is critical for normal operation heating systems. This is especially important for solid fuel thermal units. Chimneys tend to become clogged with combustion products, which reduces the efficiency of fuel use and increases the likelihood of situations that threaten not only the integrity of the property, but also the lives of people living in the house.

How and with what to clean a chimney from soot

Heating in a private home is a vital system on which not only depends comfortable accommodation, but often the property and life of the residents. A special role is played here by the system for removing fuel combustion products from the room - the chimney. Its internal surface gradually becomes contaminated with condensate and soot, while the cross-section of the chimney channel decreases, draft decreases, and the complete removal of smoke from the room is disrupted.

Over time, the chimney becomes clogged with soot, and its ability to remove combustion products decreases.

Why does the chimney become dirty?

Clogging of the smoke channel occurs during the combustion of fuel, when vapor and solid products are released from it and carried away by the flow of furnace gases. But under certain conditions they do not fly out completely into the chimney. This happens under the following circumstances:

Signs of a clogged chimney

When the flue gas exhaust channel becomes clogged, it will be immediately visible. The main signs of a clogged channel will be the following:

What to do if the chimney is clogged

Before the start of the heating season, you must inspect the inside of the chimney for blockages. In the warm season, birds with a nest may settle in it, or debris may appear, blown into the pipe by the wind. To avoid this, the chimney must be equipped at the installation stage with a cap with a mesh that prevents such situations.

In such a case, the house should always have a backup heating unit in the form of a heater or an electric heater built into the heating system.

Having provided yourself with warmth with its help during the cold season, you can carefully consider the situation and think through options for getting out of it.

The presence of draft in the firebox must be checked every time the stove is ignited - the flame must deviate towards the chimney

How to clean a chimney

The purpose of this operation is to timely clean the walls of soot deposits and debris that has gotten inside (during the off-season period). When cleaning, you need to check all sections of the chimney and the stove itself. The last step is to clean the ash pan and firebox. Timely cleaning of the chimney reduces fuel consumption and makes the operation of the stove safe.

In practice, three main cleaning methods are used, two of which are preventive:

1. Chemical and biological methods. They are used as a preventive measure using compounds that soften soot and lead to its partial removal from the smoke duct.
2. Mechanical. It is carried out by direct impact on the soot layer with various tools in order to remove it.

If you use such products correctly and in a timely manner, you can avoid involving a third-party specialist in cleaning the chimney.

Biological methods for cleaning chimneys

All biological methods are based on adding some substances to a burning firebox. Among the common products you can consider the following:

• potato peelings. This is an old folk remedy for preventing the formation of soot deposits, the simplest and always available. The peels need to be prepared in advance, accumulating at least half a bucket. It needs to be dried and added to the firebox at the end of the fire. When burning, potatoes release starch, which softens the soot layer well. It happens that it simply falls down in layers or pieces, part of it is carried away along with the furnace gases. This operation is also recommended to be performed before performing mechanical cleaning;
• rock salt. The method is used when igniting the stove. The compound formed when the salt is heated softens the soot layer well. A tablespoon of salt should be poured on top of the fuel;
• aspen firewood. Firewood made from this type of wood has a high calorific value, so it is placed at the end of the firebox. Hot furnace gases simply burn soot directly on the walls of the chimney. The danger of this method is that large layers of soot during combustion at high temperatures can destroy the chimney and cause a serious fire. Therefore, this method should be used regularly, laying aspen firewood in small portions. For the same purpose, you can use peeled bark birch firewood;
• shell walnuts. The use of this product is also associated with a high combustion temperature. Therefore, they can serve as an alternative to aspen firewood. But the shells can be used in quantities of no more than two liters at a time. Otherwise, the chimney may overheat with predictable consequences.

Walnut shells should not be burned in large quantities - they can overheat the chimney. Burning dried peelings destroys the soot layer due to the release of starch. Rock salt, when heated, releases substances that soften carbon deposits on the walls of the chimney. Aspen firewood burns soot on the walls of the chimney due to the very high combustion temperature.

Chemicals for removing soot deposits

There are several such products, and they can be divided into two groups: household products and special chemicals. The first group includes:

1. Naphthalene. This is an effective and completely reliable tool. Under its influence, the soot is stratified and carried into the firebox. It is placed in the oven on burning wood. Significant disadvantage is a pungent unpleasant odor remaining in the room. Therefore, it is not used in open hearths and fireplaces.
2. Blue mixture. It's easy to make yourself if you have a few common ingredients on hand. You need to mix:
   • five parts copper sulfate;
   • seven parts of saltpeter;
   • two parts of middle fraction coke.

Special chemicals are also used for cleaning chimneys for preventive purposes. Given the existing demand, the industry produces a variety of compounds designed specifically to combat soot. The form of release can be briquettes, similar logs, powders or solutions. Their action is based on the decomposition of smoke in the firebox into components that do not form soot.

The convenience is that the methods of using them are described in detail in the instructions for use, and they are divided into portions. You can burn these products along with the packaging, which is also very convenient. The following products are popular:

There are quite a lot of anti-carbon products on the market, so you can choose for yourself by testing the best option.

The “Jolly Chimney Sweep” tablets will help you get rid of soot in the chimney no worse than a professional chimney sweeper. The blue mixture must be prepared independently from three not very common components. This product is recommended for use only in closed cells combustion of naphthalene leaves behind an unpleasant odor that will dissipate within a few days

Mechanical cleaning methods

Mechanical methods are radical and are recommended for use at least twice a year. They are done from the top of the chimney using various brushes or attachments for power tools, and the final cleaning is done from below from the hearth, fireplace or stove firebox.

Chimney sweeps use special brushes on a long rope

As preparatory activities Before cleaning a thick (from two millimeters) layer of soot, potato peelings or other listed products are burned.

In this case, you may need following materials and tools:

To clean the pipe from above, you need to use a roof ladder that is well secured to the roof . In any conditions, you need a reliable safety rope.

Work at height can only be carried out in dry, windless weather. Before climbing to the roof, you should not take drugs that reduce the reaction, and especially alcoholic drinks.

Before starting work, the oven must be cooled. Clear the combustion space completely of unburned fuel residues and ash. Firebox door, vent, and lids hob close tightly and cover with a wet cloth to prevent soot from entering the room. The gate must be opened completely to avoid re-clogging the channel with fallen soot.

The chimney pipe must be freed from the head, after which:

DIY ruff

If for some reason you don’t have a brush on hand, you can make one “on the go” from a plastic bottle. To do this, you need to cut several tiers of strips up to 12–15 millimeters wide on the body so that they bend vertically. To make the device heavier, you can add sand to the bottom.

A good chimney brush can be made from a plastic bottle

Cleaning Stainless Steel Pipe

A special feature of the product is the high quality of the internal surface of the chimney. This prevents a significant amount of soot from settling on the walls. Naturally, this is true for a properly manufactured chimney, subject to the rules for firing the stove. If persistent carbon deposits have formed, it must be cleaned urgently. To do this, use the following methods:

In order not to carry out additional “experiments”, you need to heat the stove only with suitable fuel - well-dried hardwood firewood. At the end of each firebox you need to add one aspen log for prevention.

Cleaning soot from stainless steel sandwich pipes

Cleaning internal sandwich pipe with her correct operation will be needed very rarely. However, if such a need arises, you can use an elongated brush made of fine bristles. The flexible composite hose is rotated by an electric drill, and cleaning is done through a tee from below. The thin bristles of the brush do not damage the surface of the pipe, effectively cleaning the surface.

This chimney is easy to dismantle and clean each pipe individually.

Special cases of chimney cleaning

Some chimney cleaning situations require separate consideration.

How to clean a chimney pipe in a private house

The entire process of cleaning a chimney has already been briefly described above. To what has been said, you only need to add that if the smoke channel is severely clogged, the first operation is to punch through the soot with a core without additional accessories. Only after this are brushes of different sizes and designs used sequentially.

When performing work, care should be taken to create safe conditions for work.

When working at height, be sure to wear a safety rope

Cleaning the chimney in the bathhouse

The chimney in a bathhouse is usually simpler. And most often it is made from stainless pipes, which requires special attention to its cleaning. In order not to negate its main advantage - the high quality of the internal surface - cleaning should only be done with soft plastic or made from natural materials brushes. It is easiest to manage with straight pipelines, and if there are elbows - let us remind you that there should be no more than two of them - you may have to dismantle the chimney if special windows for cleaning were not provided in it during installation.

Otherwise, preventive measures and cleaning are carried out in the same way.

Cleaning the chimney pipe from resins

When considering the composition of flue gases, you need to pay attention to two main components - water vapor from fuel and vapors from creosote, which is difficult to ignite. Mixing and settling on the walls of the smoke channel, they form a resin that is difficult to remove due to its viscosity and good adhesion to various types of surfaces.

The only effective way to combat tar deposits is to prevent its formation. For this, various products are used that are produced specifically for this case.

HANSA effectively protects chimney walls from tar formation

For example, the known composition HANSA is a fine crystalline substance. Part of it turns wood into resin and water vapor, and the second, reacting with the resin substance, promotes its decomposition and combustion at the temperature in the furnace. The remaining resin on the walls turns into a brittle crystalline composition that crumbles inside the furnace.

This composition is placed inside a burning firebox. The frequency of use at the beginning of operation of the heating unit is daily, then you can switch to using it once a week.

Cleaning a curved chimney

Bends in the smoke duct are always a necessary measure caused by the design features of the building. However, periodic cleaning is necessary. For this purpose, the pipeline design includes elements that can be used to perform this operation easily and simply. These are special hatches, when opened, it becomes possible to access the straight section of the bend. It is not recommended to make the length of inclined sections more than a meter in size. The number of bends on one pipe should not exceed two.

If there is no window for cleaning on the outlet elbow, then the chimney will have to be disassembled

How to clean the chimney of a gas water heater

The reason for cleaning the chimney of a gas water heater is its banal clogging with deterioration of draft. In a city apartment, this is all the more dangerous because the threat arises for many people at the same time. One of the signs of deteriorating traction is the “popping” of the column igniter.

Cleaning process exhaust pipe from a gas unit is practically no different from such an operation with conventional chimneys. The same brush is used. Recently, specially designed vacuum cleaners have often been used to reliably clean the surface of the pipe and collect contaminants. In difficult cases, when deposits cannot be removed with a brush or vacuum cleaner, special chemicals are used to soften and remove them. Considering that the use of preventive agents on the dispenser pipe is impossible, immediate measures should be taken if signs of clogging are detected.

It must be recognized that the success of using solid fuel furnace equipment depends to the greatest extent on the correct operation of the units and careful selection of fuel for it. In addition, you must regularly use prophylactic agents and know ways to get rid of problems with clogged chimneys. Then stoves and fireplaces will delight you with beneficial warmth in your home for a long time. I wish you success!

To clean a chimney pipe in a private house, you need to know some nuances, otherwise you risk damaging the structure and wasting your time by performing this time-consuming work poorly. If you are faced with a choice between chemical and mechanical cleaning, feel free to choose mechanical, as it is much more effective. If necessary, consult a specialist.

A clogged chimney occurs for a number of reasons. Often the culprit may be a foreign object getting into the pipe. For example, birds or other animals that bring with them nesting material that completely blocks the smoke escape. Excessive soot accumulation (a natural byproduct of the combustion process) can also cause blockages. Finally, large amounts of leaves, branches and other debris can block the chimney vent.

Sometimes incorrect design during construction can cause further frequent blockages. This is the most difficult reason to eliminate, since in most cases it will not be possible to get rid of it on your own, and contacting qualified specialists can cost a lot of money. Often, to completely eliminate the problem, it is necessary to completely dismantle the stove or fireplace in order to build a new firebox and smoke exhaust system. If you do not have the relevant experience and do not know how to clean a chimney, under no circumstances try to do it yourself.

Why is soot dangerous?

During the combustion of wood or coal, amorphous carbon (soot) containing small particles is formed solid. Soot occurs when hot particles interact with cold air, causing condensation. Because this process occurs in the air inside your home, the soot is virtually invisible until it begins to settle on walls and other surfaces as a black residue.

When interacting with moisture in a room, soot can significantly deteriorate the quality of water and damage houseplants and make the surrounding air unbreathable.
Staying in a room with high levels of soot in the air for a long time can cause coronary heart disease, asthma, bronchitis and many other respiratory diseases.

The most dangerous effect of fumes is on people suffering from cardiovascular diseases, increasing the risk of a heart attack.

If newborn children are in a contaminated room, this may affect the development of their upper and lower respiratory tract.

The danger of carbon monoxide poisoning is a major concern when it comes to heating a room with wood or coal.

Traditional methods of contactless cleaning

Please note that contactless cleaning eliminates the problem only for a while. If you have difficulty with mechanical cleaning, use the services of professionals.

People often use following methods to combat soot and burning:

• Burning potato peels together with firewood;
• Placing a bag filled with bricks into the pipe;
• Using pine firewood to clean the chimney.

Please be aware that none of these methods are foolproof cleaning methods and are not guaranteed to be completely safe. The best methods are mechanical or chemical cleaning. In some cases, you can combine several options if your design allows it.

Chemical cleaning

Sodium chloride

Sodium chloride, also known as table salt, is a simple chemical that is easy to find. Place some salt on the fire while it burns. The salt will begin to react with the water in the burning wood, which will create a weak acid that will move up the chimney and will dissolve a small amount of soot. Use this method with caution. Do not use sodium chloride if you have a metal chimney, as the acid will cause corrosion when it interacts with metal.

Copper sulfate

When choosing an industrial flue gas scrubber, one of the most effective ingredients is copper sulfate. This material reacts chemically with the soot and causes it to burn at a lower temperature than normal. Like table salt, copper sulfate, when combined with water, creates a sulfurous or sulfuric acid, which can damage the inside of your chimney.

While chemical cleaners can prevent soot buildup, the only way to effectively remove the clog is to manually clean the inside of the pipe with a special brush. Chemical cleaners should never be the only cleaning method. In addition, excessive use of chemicals can damage the chimney, especially metal-lined chimneys, significantly reducing their lifespan. Before using any chemical cleaner, read the instructions carefully to avoid fire. If the chimney is not working properly and smoke is coming back, do not use chemicals under any circumstances, as this may cause serious poisoning.

Mechanical chimney cleaning

Do-it-yourself mechanical cleaning of a chimney is a very labor-intensive task that requires considerable effort and time. There are four general cleaning methods. Some of them require the presence of more than one person, but all four methods involve a set of the same tools.

To clean the chimney you will need:

• Brush for cleaning the chimney;
• Smoke exhaust rods, rope and traction rings (depending on the method);
• Pipe plug;
• Fabric for flooring and furniture;
• Ribbon;
• Mirror;
• Metal bucket;
• Shovel and broom;
• Flashlight;
• Protective mask/goggles;
• Ladder.

Measure the width of the chimney before purchasing a special brush to choose right size.

Never skimp on the quality of consumables. This can affect both the quality of cleaning and the integrity of your structure.

Basic mechanical cleaning methods

• Top-down rod method. For execution this method cleaning must be on the roof. Insert the brush into the hole to clean the inside walls by lifting the brush up and down several times. The brush should be connected to flexible metal rods to increase the length of the brush as it moves further down the chimney. Use this cleaning method if you want to avoid getting soot on furniture and walls in your home. It is recommended to close the firebox to completely prevent soot from getting from the walls of the chimney onto things in the living room.
• Bottom-up rod method. This method is similar to the previous one, but to clean you need to be in the house, not on the roof, working with the rod from below. This is much safer since you don't have to climb onto the roof, but it means it's impossible to avoid soot and dust getting on things in your home. To significantly reduce contamination, use a tarp to protect your furniture from excess fumes.

• Cleaning with additional weight. It is recommended that this cleaning be carried out using the same algorithm as the top-down rod method, but instead of using a smoke brush, rope, pull rings and weights must be attached to the flexible metal rods. Add rings and any weight of at least 9 kilograms to the end of the rope, then lift and lower this design into the chimney from the roof. Don't forget to close the firebox in your home to prevent dust from getting on your interior items.
• Double line method. This method requires the participation of two people. Thread the rope through your brush (use a tension ring to hold it in place if necessary). One person takes the brush and rope to the roof and, holding one end, lowers the installation down the pipe. The person in the house grabs the other end of the rope. Each person takes turns pulling the rope to thoroughly clean the chimney with a brush. Be prepared for a lot of dust in the house after the procedure. Be sure to use a tarp or any other fabric to cover the floor and furniture.

Step-by-step instructions for mechanical cleaning

1. Prepare a cloth to collect dust and lay it in front of the fireplace (stove).
2. Wear a mask and gloves.
3. Light the pipe carefully with a flashlight to accurately determine its size.
4. Make sure your cleaning brush is at least slightly longer than your chimney.
5. Place a tarp or old, unwanted sheet over the fireplace. Use fireproof tape for these purposes to avoid incidents with flames (especially if you use a torch or candle instead of a flashlight).
6. Push the brush up the chimney, turning it inside if necessary.
7. Repeat this process until you reach the top of the chimney.
8. Take a look at the chimney using a flashlight. If the walls are still dirty, repeat the previous procedure again.
9. Use a hair dryer to heat the chimney. Direct the heat source towards the chimney for approximately 8 minutes.
10. Light a small piece of paper in the firebox to check the quality of the work done. If the smoke rises up and does not return, then the cleaning has been successful. Otherwise, you can repeat the previous steps.
11. To make sure your chimney is intact, have someone look outside at how the smoke is coming out. If smoke comes out of several holes, then the chimney is most likely damaged. In this case, do not try to do anything yourself, but contact qualified specialists to avoid a fire.
12. If everything went well, remove all dust and fumes from the firebox using a vacuum cleaner.
13. This procedure must be carried out at least once every month and a half.

Checking the quality of cleaning

The easiest way to check is to shine a flashlight into the chimney. If you don’t find any gray, brown or black deposits on its walls, it means the cleaning was done efficiently. The absence of an unpleasant odor while burning wood also indicates that there are no harmful substances left in the chimney. During cleaning, foreign objects may enter the chimney (for example, a piece of rope, fibers from a brush, etc. Consumables).

Anyone who has a stove, fireplace or boiler inevitably faces the problem of cleaning chimneys. Over time, the passage of any chimney becomes narrower due to the accumulation of soot in it.

In addition to narrowing the cross-section of smoke and ventilation ducts, deposits prevent the chimney from warming up. And most importantly, a blockage of soot and dust significantly reduces draft and contributes to the accumulation of carbon monoxide in the room. The most unfavorable option is the ignition of the sediment, which contributes to the destruction of the structure. Sparks from burning deposits can also cause a serious fire.

If nothing is done, the stove or gas boiler will become unusable over time. Cleaning chimneys in private and apartment buildings This is usually carried out by a chimney sweep from an appropriate company authorized to carry out chimney maintenance. He has special equipment for removing dirt, mainly using a special brush or metal brush. You can call a specialist by calling the service company.

When is it necessary to clean the chimney?

Regardless of the quality of the stove, the chimney will still have to be cleaned at some point. It is the matter of time. With proper installation of a stove or fireplace, you can do without this procedure for many years, especially if you use dry wood and refrain from burning household waste. Firewood must be stored for at least a year and a half before being consumed. The type of wood is also important. When using pine or spruce firewood, cleaning will be required faster (due to the presence of resin).

The first signal of a clogged stove (fireplace) chimney pipe is dark smoke from combustion products. If hardwood firewood or pellets are used, the smoke is clear, sometimes white. Its darkening indicates the accumulation of soot, carbon deposits and dirt. The second sign is that the firewood does not make any noise while burning, the flame becomes dark orange. When these signs appear, it’s time to think about calling a chimney sweep or getting ready to clean it yourself.

But before you clean the chimney yourself, it is still better to inspect the pipe first.

Stovemaker's note: Any chimney must have a cleaning pocket at the bottom through which dirt and debris are removed.

A cleaning weight with a diameter corresponding to the size of the chimney should be in every home. If it easily passes into the pipe, then the reason for the poor operation of the stove is something else. If the weight stops in one place, then the pipe is clogged and the duties of a chimney sweep cannot be avoided.

However, there are folk remedies, which allow you to postpone this work. The most ancient folk way- place raw potato peelings (or chopped raw potatoes) into the heated oven.

When they burn, starch is released, which softens the soot deposit. One part of the deposits flies out through the pipe, the other falls into the stove (fireplace). To prevent the formation of soot deposits, you can also burn rock salt at the same time as firewood.

The most reliable, but also dangerous method is to place a good armful of aspen logs into a heated stove. , without closing the door. The stove will begin to hum, the soot will ignite, and a flame will appear from the chimney. This method can be used if the chimney is really very reliable.

Cleaning equipment and rules

The stove chimney (chimney) is cleaned if the layer of soot and soot reaches a thickness of 2 mm. Sequence of work:

Basic accessories:

• for pipe with round- a metal brush with a diameter 20% larger than the dimensions of the pipe;
• for pipe with square section- brush with metal bristles;
• scraper;
• for breaking through blockages - a metal core.

If the soot layer is too dense, then before using the brush it must be cleaned with a scraper. Only after this can you use a brush (or brush). The brush should move up and down in smooth movements. The brush should be equipped with holders that will connect when moving downwards. If a blockage is detected (garbage or fallen brick) that the brush does not allow through, you need to use a metal core with a diameter of 2/3 of the pipe cross-section, which is attached to a cable - throw it into the center of the structure, trying not to hit the walls, so as not to destroy the structure. In addition, the core can be used to weigh down a brush or brush.

If the house has an open fireplace , connected to a straight pipe, it is quite possible to clean it with a long-handled brush straight from the firebox. After cleaning the pipe, it is also necessary to clean all the windows for cleaning, the air vent, the door and the firebox itself.

Chemicals to combat soot

Stovemaker's note: in large Russian stoves it is necessary to burn two Chimney Sweeper briquettes at a time.

“Chimney sweeper” consists of sawdust, coal wax with coal dust, ammonium sulfate, urea, zinc chloride, sodium sulfate, silica and phosphorus oxide. This product is especially effective for brick chimneys.

Before using the Chimney Sweep for the first time, you must make sure that there are no loose bricks, debris, bottles or bird nests in the chimney. The most effective way to burn briquettes is on hot coals. Additives entering the pipe affect its inner surface for up to two weeks. All this time, soot falls into the firebox from above. After two weeks, it is advisable to clean the elbow and smoke damper.
