How to clean blackened silver jewelry.

Silver is an unstable element that can easily react chemically with sulfur, resulting in blackening.

Moreover, human sweat also contains a large amount of sulfur, which will work when it comes into contact with silver jewelry. It could also be due to an oxidation reaction with air. It will cause the silver jewelry to turn black, which is a normal phenomenon.

If the blackening is not too severe, you can go to the market and buy silver paper to wipe it briefly, or dip a toothbrush in a little toothpaste to wipe it, or wash it by hand, rubbing soap or dish soap.

Of course, remember to dry it with a cotton cloth after washing. If the blackening is severe and it is difficult to clean it yourself, you can also go to a silver store to find a professional to help.

1. When cleaning the glossy silver jewelry, squeeze a small amount of toothpaste into your hand, add a little water to knead the rich foam, gently rub the jewelry, wipe it with a soft cloth until it is bright, then rinse it with water, and wipe it dry with a cloth. The left side is not rubbed with toothpaste, and it is black. The right side is the one that has been wiped with toothpaste, and it is as bright as new.

2. When cleaning old or textured jewelry, squeeze a small amount of toothpaste into your hand, add a little water to knead a rich foam, and gently brush the jewelry with a soft small brush, then rinse it with water and dry it with a cloth.

3. When cleaning the silver chain, you can find a small plastic bag, put the silver jewelry in, then squeeze a small amount of toothpaste into your hands, add a little water to knead the rich foam, pour the foaming toothpaste water into the bag, rub it repeatedly, and then rinse it with water and dry it with a cloth.

If the silver jewelry is not worn for a long time, the surface of some silver jewelry will appear patina, this is because it contains a small amount of copper, be sure to wipe it clean with a silver polishing cloth, so as not to leave sweat stains on the jewelry to cause corrosion, and then put it into the sealed bag or packaging box we attached, so as to isolate the air to avoid oxidation of silver jewelry to turn yellow and black.
