It is best not to use a product that contains bleach. It contains more aggressive substances that can adversely affect the surface of the product.

Baking soda

Soda is a well-known cleaner for various coatings. With its help you can remove not only pollution, but also oxidation. It can only be used for processing low-grade coins, as it is an abrasive substance and can scratch the surface.

Make gum out of sodium bicarbonate and a small amount of water. Use your fingers to rub the composition into the product until it starts to shine.

Acetic acid, ammonia

Green spots and blackened spots can be scrubbed using a mixture of baking soda and ammonia. Add a few drops of alcohol to the soda powder to form a mushy mass. Then put on the coin and rub until the bloom disappears.

With rubbing alcohol you can clear silver coins of both low and high samples. This is a very common method of purifying precious metal.

A tablespoon of the acid must be diluted in 100 ml of water until completely dissolved. After this thing is made of silver down there for 2-3 seconds. Then you need to wipe the cover with a clean cloth. You can use juice of natural lemon instead of powder, this substance is less aggressive.

With the salt

We need to take a piece of foil and put a mixture of salt and water on it. Salt is better to take finely ground. Make a mushy composition of these ingredients and place them on the foil. Then a silver item is put in there, which needs to be cleaned and covered with gruel completely.

The edges of the foil need to cover the composition and leave it for several hours. Try to act carefully so that the metal is not scratched during these movements. After cleaning, rinse the product with warm water.
