Silver is chemically active, so it will react with sulfur dioxide in the air to produce black silver sulfide. When the surface of silver ornaments is oxidized to black, the following maintenance methods can be adopted to restore the beautiful luster of silver ornaments.

1. You can add baking soda powder to clean water and then clean it.

2. Wipe it with silver cloth and silver paste [it should be available in general jewelry stores].

3. Wipe the ornaments with a soft cloth dipped in some toothpaste, then wash them with clear water and wipe them with cotton cloth. (Toothpaste works well. )

4. Soak the silver in water, then wash it with clear water, wipe it with cotton cloth and keep it dry. However, it is suggested that silver washing water should be used as little as possible, because silver washing water is a chemical product. Using the corrosiveness of silver washing water to clean silver ornaments will cause harm to silver ornaments for a long time.

Finally, remind everyone that it is best to avoid contact with seawater and hot springs. If you don't wear it, you can put it in a container that is isolated from the air, such as a velvet bag or a jewelry box, which will make your silver jewelry as new!
