2. Wipe with cotton dipped in white vinegar, and black silver sulfide will dissolve in ester acid or soak in overnight tea. Silver ornaments will shine again.

3. You can also use toothpaste (try to choose a green and transparent rice grain shape with fine particles to avoid scratching the surface of the silver jewelry), directly wipe the toothpaste on the silver jewelry, and then add a little water to rub out the foam. If there is a seam, brush it with a toothbrush to prevent foam from entering the seam.

After washing the silver bracelet, avoid contact with water vapor and chemicals, avoid swimming with it, and especially don't take it into the sea.

The silver bracelet is wiped with cotton cloth after it is taken off every day, and put into a jewelry box or bag for sealed preservation when it is not worn.
