Jewelry forged with this pure silver is stronger and less prone to wear and deformation. The real 999 sterling silver is as soft as pure gold and is made of alloy sterling silver. How to maintain sterling silver jewelry? The biggest reason for the oxidation of silverware is oxygen in the air, so blocking the air is the best maintenance method. For example, put the silverware in a sealed plastic bag and then put it in a pearl box to block the contact between air and silverware. When the silverware is oxidized, you can use silver washing water or a piece of silver cloth to wipe it, but the silver washing water is more lethal, so please try to wipe it with a silver cloth unless you have to. If it is bright with silver water, it should be picked up immediately and rubbed gently to clean the chemicals on the surface. In addition, soak in 90% alcohol 12 hours, wipe clean and dry; Or squeeze toothpaste on a dry cloth and wipe it directly, and the effect is also very good.
