How to clean silverware when it turns black?

Silver jewelry turns black because it reacts with some substances in the air, so ordinary washing can't remove the black on the surface of silver jewelry.

There are two main ways to clean black silver jewelry: physical and chemical.

The principle of physical whitening method is to use small particles in the medium to remove the oxide film on the surface of silver jewelry by friction, which is equivalent to peeling a layer of silver jewelry.

The specific methods mainly include:

1, brush with toothpaste and toothbrush.

2. Apply lipstick on the cloth, then wipe the silver ornaments, and finally rinse them with water.

3. It is absolutely effective to apply the correction fluid to the silver jewelry and wipe the silver jewelry with a cloth before the correction fluid dries.

The method of chemical whitening is relatively simple, and its principle is to destroy the oxide film on the surface of silver jewelry through chemical reduction reaction. Compared with physical methods, chemical methods are relatively simple, and will not leave scratches on silver ornaments, which is more suitable for our daily life.

Specifically, there are the following methods:

1. Soak in Coca-Cola containing carbonic acid 12 hours.

2. Wash and cook with vinegar, which contains acetic acid.

3. Soak overnight tea, which contains oxalic acid.

4. Wipe with a silver cloth, which has chemical components to remove silver oxide.

5. Soak in silver washing water for one or two minutes, and then rinse with plenty of water. You can find silver washing water, a professional collection store, in Taobao's online shopping mall.
