If it is bronze, bronze and other copper alloys, there will be lead and other harmful metal substances. The brass jewelry will rust for a long time, without the previous luster. If you want to recover the previous appearance, you must go through two steps. The first step is to use acidic liquid to wash off the green rust on the surface of the jewelry, and then use the passivation of the jewelry to cover a layer of passivation film on the surface of the jewelry to prevent the jewelry from oxidizing and rust. Generally cleaning can be cleaned directly at home, but the passivation treatment needs to be made in a specialty of jewelry. The passivation film for copper products is very simple, and the cost is not high. After these two steps, the jewelry can be renewed as before.nDear ~ Answer can give you help if you help you, thank you for your support ~ Finally, I wish you a happy New Year!
