As we all know, wearing silver jewelry is not only good for your health, but also can increase your personal charm. But for silver jewelry, it is easy to turn black, which affects the beauty. So how should we deal with the blackening of silver bracelets? Now let's follow the editor of Star Harvest to learn some processing methods and techniques!

1. The black on the silver bracelet can be quickly erased with silver wiping cloth and silver washing liquid. However, this method is not recommended for common use, because these things are corrosive after all, which will cause silver bracelets to become more black after use.

2. Wipe hard with cotton cloth or linen cloth to make it black, which is a little difficult. Of course, apply some white vinegar on the bracelet, and then wipe it with a piece of cotton cloth to remove the black color. But it must be noted that it is better not to scrub with hydrochloric acid or nitric acid.

3. If the silver bracelet turns black soon after polishing, check whether there are toxic substances or acidic and strong oxidizing substances in the working or living environment.

4. Toothpaste is the best helper to deal with the blackening of silver bracelets. The toothpaste is rich in fine calcium carbonate particles, which can wipe away the oxide on the surface of the silver bracelet. So use a toothbrush dipped in toothpaste to rub it patiently for a while, and then rinse it with pure water. Of course, it's better not to rinse it with tap water. After all, tap water contains residual chlorine, which is also the thing that causes silver ornaments to turn black.

5. Wipe the silver bracelet with grain lime or white carbon ash, which can not only make it bright but also not easy to turn black in the future. Of course, it is not to scrub with water, but to dry scrub.

6. Calcium carbonate powder can be used to remove the black color on silver bracelets. Of course, after being wiped with calcium carbonate powder, it should be wiped with a clean dry cloth.

7. After the silver bracelet is polished, care must be taken to avoid contact with various strong acids and alkalis, oxidizing substances and sulfides. So when you wash, you'd better take off the silver bracelet.
