What happened to the black and silver bracelet?

The first reason is that silver bracelets come into contact with sulfur-containing things, such as soap for washing hands, detergent for washing dishes, and even some women's cosmetics. If the silver bracelet is exposed for a long time, it will slowly turn black, which is a normal chemical reaction.

The second reason is that in summer, some people sweat easily, and some people sweat with high sulfur content. Then the silver bracelet worn on the hand is exposed to sweat every day, and it will gradually turn black every summer. The main reason is that the silver in the bracelet turns black after reacting with the sulfur in sweat. The third reason may be related to the working environment, because some people work in chemical plants and wear silver bracelets exposed to the air. Because the air in chemical plants contains chemicals, the bracelets they wear will gradually turn black over time. Is there any way to brighten the blackened bracelet? When we find that the silver bracelet worn on our hands turns black, we can use two small methods to make the bracelet bright again. The first small method is to dip a little toothpaste on the surface of the silver bracelet with a soft toothbrush. This little method is very practical. The silver bracelet, which is basically black, will gradually brighten after being brushed with toothpaste for several times. The second small method is: you can buy professional silver cloth, which can be bought online. It is also very convenient to use, that is, put the cloth on the bracelet and wipe it from one side to the other. Never rub back and forth, because the back and forth friction will rub out the pattern of the bracelet, so the bracelet will change from black to bright after rubbing with silver paper. Daily maintenance of silver bracelets If we try to take off the bracelets when washing dishes, avoid contact with chemicals and keep them dry at ordinary times, then we should take off the silver bracelets and wipe them with soft cloth or professional silver cloth. It's cold, so you should take off your silver bracelet in the hot spring, because the water in the hot spring has high sulfur content.
