How to clean silver jewelry
Silver, the chemical name Ag, is a relatively active metal. The sulfur and oxides in air and other natural media have a certain corrosive effect on silver, because the oxidized silver oxide and silver sulfide are black. Therefore, after the silver jewelry is placed or worn for a period of time, some tiny black spots (silver oxide) or black film (silver sulfide film) will appear, and the time is long. With the spread of black spots and black films, silver jewelry It slowly changes color, and even becomes black. This is the reason why the silver jewelry we see is black, so it is a normal natural phenomenon that the silver jewelry turns black. There is nothing strange about it.

The specific methods are mainly: 1. Scrub with toothpaste and toothbrush. 2. Apply lipstick to the cloth and wipe the silverware, then rinse with water. 3. Apply the correction fluid to the silver jewelry, and use a cloth to wipe the silver before the correction fluid is dry. It is absolutely effective. The chemical whitening method is relatively simple. The principle is to destroy the oxide film on the surface of the silver jewelry by the reduction reaction in the chemical. Compared with the physical method, the chemical method is relatively simple, and the silver jewelry is not left on the silver jewelry. Traces are more suitable for our use in everyday life.
