If not worn, it can be stored in a sealed bag to avoid accelerated oxidation due to prolonged exposure to air. 2. When the silver jewelry is oxidized and slightly blackened, wipe it with a Silver cloth, wash it with water, and finally dry it with a clean and delicate cotton cloth. Because the Silver wiping cloth contains special ingredients, do not wash it with water, so as not to lose its Silver wiping effect. 3. If you don't have a Silver wiping cloth at hand, you can use a soft cloth with a little toothpaste to wipe it, then wash it with clean water and dry it. 4. If the oxidation is serious, you need to use Silver washing water to clean it. It is not recommended to use it frequently if it is not necessary.
