To prevent oxidation, the best way is to isolate the air. For example, the surface of the brass is coated with transparent grease or paint. 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. Brass maintenance methods are as follows: 1. Store the jewelry separately and mix it with other accessories or hard objects to avoid grinding the surface. 2. Avoid contact with sweat for a long time, thus corroding the surface. 3. Please remove the product during bathing or washing to avoid direct contact with acid and alkali substances. 4. Use clean water, toothpaste, soft brush to restore the surface brightness (grinding, scratching will not be able to recover). 5. When collecting, please use cotton cloth or facial tissue to remove surface sweat and dirt and then store it in sealed bag. https://img.alicdn.com/imgextra/i3/641317732/O1CN01MVQcWV26zIvIBPZSE_!!641317732.jpg https://img.alicdn.com/imgextra/i1/641317732/O1CN01wH9xR726zIvMLk85U_!!641317732.jpg
