I have a amati wooden B flat clarinet. I play it everyday and it plays just fine. But on the bell, at the bottom rim and top rim is covered in tarnish. I asked my band director what I should do about it. And he said that only thing he knew that could get rid of it was lighter fluid, but he didn't think that would be such a smart move on a wooden clarinet. (The rim isn't wood though.) Does anyone know what I can do to get rid of the tarnish?
