I've been drumming for almost 2 years now, and I've never had this problem, and I hope I never do, but I probably will. But anyway, I've seen remedies for this sort of thing being mentioned on various forums, etc. but will all obviously affect the way your cymbal sounds, meaning that it's just better to buy a whole new cymbal. (Unless of course you want your cymbals to sound crap, but I doubt anyone does) =p
