To prevent oxidation, the best way is to isolate the air, such as coating transparent grease or paint on the brass surface. For brass that has been oxidized, It can be polished with sand, or it can be reduced in a reducing atmosphere such as H2 or CO at a certain temperature. The brass maintenance method is as follows: 1. Do not store jewelry separately with other jewelry or hard objects, avoid grinding the surface. 2. Avoid prolonged contact with sweat, which will corrode the surface. 3. Please remove the product during bathing and laundry to avoid direct contact with acids and alkalis. 4. Use water, toothpaste, and soft brush to restore the surface brightness. 5. When storing, please use cotton cloth or tissue paper to remove the surface sweat and dirt before storing in a sealed bag https://img.alicdn.com/imgextra/i2/641317732/O1CN01nK6ZDa26zIvQlBxjY_!!641317732.jpg https://img.alicdn.com/imgextra/i2/641317732/O1CN01ZnVluX26zIvQlEJXk_!!641317732.jpg
