The easiest way is to gently clean the surface with toothpaste and some water. Or use a small jewelry brush to clean up the fine seams of the silver ornaments, and then gently wipe the surface with a silver cloth, and the original aesthetic feeling of the ornaments can be restored immediately.

1, wipe the silver cloth:

Wipe the surface with a silver cloth. If the oxidation is serious, it must be wiped off by force. Then clean the black oxide on the surface with detergent and dry it with paper towels.

2. Silver washing water:

Because silver washing water will corrode the surface of silver ornaments, it can only be used in the case of serious oxidation of silver ornaments, and cannot be used repeatedly. Immerse the silver ornaments in silver washing water for 5 seconds, and then wash the surface with detergent. Don't let the silver washing water remain on the surface, dry it with a paper towel.

Extended data silver will turn black:

First, because everyone's endocrine and physical condition are different, some people's sweat contains more acid, some people have less, and some people's body fluids have high sulfur content. These are all substances that cause the surface of silver ornaments to turn black, so everyone will have different results when wearing silver ornaments, and some people will be as bright as new after wearing them for half a year.

Second, sulfur, nitric acid and oxides in air and other substances (such as eggs and cosmetics) have a certain corrosive effect on silver. Silver jewelry is worn for a long time, and the combination of sulfur and silver will form a black silver sulfide film on the surface of silver jewelry. At first, it will show some tiny spots, and then spread into pieces, forming what people usually call silver scales, turning black and affecting the surface luster of silver jewelry. People usually mistake it for fading.
