I have a friend that has been trying to remove the oxidation off of his bronze cymbals. He says they are seriously affecting the sound and all and he is anxious to remove them. He has tried scrubbing them with soap and water and soft rag, but the non-oxidized parts just get shiny and the oxidation remains.
I was thinking that perhaps some sort of acid, weak might help to remove it. Some other people I've talked to mentioned various cleaning supplies, countertop cleaners etc. Any suggestions?
