How to clean nickel silver from darkening and blackness
The serving alloy is often subject to darkening. There are several reasons for the change in the natural color of cupronickel:- increased air humidity;
- violation of product storage rules;
- failure to follow instructions for caring for cutlery.
Cleaning with soda
The simplest and most common method for removing minor stains. Dissolve 50 grams of baking soda in one liter of warm water. First we wash the products with detergent, then rinse in the prepared solution. If the stains are not removed, rub the contaminated areas with baking soda powder. Rinse cleaned instruments under running water. cold water and wipe thoroughly with a dry cloth.
Cleaning with alcohol
If the serving items are slightly darkened, it is enough to wipe them with an alcohol solution using a soft cloth.
Second option: Cutlery can be immersed in pure alcohol, ammonia or vodka for a few minutes. We take it out, rinse thoroughly and wipe dry.
Cleaning with vinegar
Dissolve one teaspoon of strong vinegar in water - 200 grams. We wipe cupronickel products with a napkin soaked in the solution. Vinegar is widely used to remove stains from any surface. We finish the cleaning procedure by rinsing and wiping the devices with a dry towel.
Cleaning with chalk
Let's prepare the product by dissolving 50 grams of laundry soap in a small amount of liquid. Add 50 grams of chalk and one liter of water to the soap mass. Mix thoroughly. Using the resulting solution, we polish the capricious products and wipe them dry.
A similar polishing agent is obtained by combining 0.5 cups of water with chalk and ammonia in a ratio of 30:60 (in grams).
Cleaning with eggshells
This method will remove complex and old stains. Prepare a decoction by combining the shells of two eggs with a liter of water. Boil the container with the ingredients. Dip the serving utensils into the hot broth for about a quarter of an hour. By analogy, rinse with a stream of running water and wipe.
Peeling potato broth
Bring the broth left over from boiling the potatoes to a boil. Let's put the cupronickel items in it for 20 minutes. Then rinse and dry.

Cleaning time depends on the degree of darkening. As soon as the products shine, they are taken out and rinsed.
Cleaning with foil
The method is considered the most effective. We place a shiny sheet at the bottom of the aluminum container. We lay out the devices. Fill with soda solution and bring to a boil. As a result of a chemical reaction, the foil takes the contaminants onto itself. After cleaning, nickel silver regains its original appearance, and silver leaf becomes dark.
This method is used to eliminate serious stains. If, at the end of the procedure, blackness and streaks remain, the process can be repeated.
Cleaning with foil cannot be used for cupronickel products with gold and silver frame. The coating will be severely damaged. The products cannot be returned to their original appearance.

Cupronickel is an alloy of zinc, nickel, copper and silver. Widely used for making tableware, decorations, artistic products, and in the production of medical instruments. Products made from cupronickel are found in almost every home. Cupronickel silver cutlery is the most commonly found in household use; it looks very similar to items made from noble silver, but is distinguished by its larger size. mechanical strength And affordable price. Like silver, cupronickel silverware can tarnish and darken over time. We will tell you in this article how to store cupronickel and wash already darkened appliances at home.
How to clean cupronickel spoons
To begin with, let's figure out why nickel silver products darken. Copper, present in cupronickel (for the most part), is easily oxidized, and even the nickel included in the composition (to a lesser extent) is not able to prevent this process. That is why, due to long or improper storage, cupronickel dishes begin to become covered with dark spots and streaks. To avoid such a nuisance, wash spoons and forks well to remove food debris, and then wipe each item dry. Even the smallest drop that has dried on the device naturally, will subsequently leave behind a dark stain. In a nutshell, you need to remove the oxide film from the surface of cupronickel products. On the smooth surface of the devices, it will be easy to remove the film at home, but if there are relief patterns on the product, this will be much more difficult.

You can put them aside for storage only when you are sure that the dishes are completely dry.
Some housewives prefer to clean dishes in decoction of eggshells or garlic peels. To do this, take the crushed shells of two eggs (or garlic peels), add water, and bring to a boil. Then the products are dipped into boiling water with the shells, and the products are boiled for several minutes. After this, rinse them under running water and wipe dry.
When the darkening is insignificant, you can get rid of them with a suede cloth with dry chalk powder, tooth powder, toothpaste or wet, shallow salt, but be careful, as grains of salt or chalk can scratch the surface of the product.
You can also restore the shine to spoons and forks by boiling them in a soda solution. Take it, put a sheet of foil on the bottom, pour a handful of baking soda into the pan, and lower the cutlery into it. Boil the dishes for several minutes, then rinse well under warm, running water, and wipe each item dry. With this method, even relief patterns on products are cleaned. You can replace water and soda with potato decoction, which is poured onto the foil with spoons.
Also, it copes well with darkening on nickel silver dishes. ammonia. Dilute a small amount of the product in warm water, then wash the devices with a cloth soaked in the solution and rinse them under running water. For minor darkening, you can use medical alcohol or vodka.
One relatively recent cleaning method involves soaking cutlery in fizzy drinks. Coca-Cola, Fanta, or better yet, colorless Sprite will restore purity and shine to your products. To do this, just soak spoons and forks for 10 minutes in the drink and rinse in warm water.
Do not forget to wipe the products dry after each cleaning, then dry them additionally, and only after that they can be put aside for storage. Every drop or moisture remaining on the devices will appear as a dark spot.

A little interesting information about alloy cleaning
There are many ways to restore the original color to cupronickel spoons. Conventionally, they can be classified into two groups: chemical and mechanical. The first is based on the reduction of the alloy from the oxide through chemical reactions. The second is the usual mechanical removal of oxide from the surface of the metal with cleaning agents.
Both methods are good, but have some disadvantages. Chemical method It is impossible to clean nickel silver spoons with gilding or blackening. The result may be unexpected, from tarnishing to complete disappearance of the decorative effect.
Mechanical involves the use of abrasive substances. These particles cannot be felt to the touch and cannot be seen with the naked eye. But they leave nickel silver on the surface small scratches, which are immediately invisible, but after a while turn into a dull coating. And he already remains forever. The only way to get rid of this plaque is through hours of polishing. The activity is meditative, but long and tedious.
