theres this really bad brown dirt on a tom i just bought that matched a set im selling cause it cost me 10 dollars and im sure it will help get more money for the set if i have a extra tom with it cause im sure its worth much more than 10 dollars but the dirt that mostly comes off but when it gets to the bottom of its just a bunch of little bumps that no matter how hard i scrub it just doesn't come off. can anyone help and tell me what stuff thats normal household stuff that could get it off? this stuff is some really bad dirt and at the parts im talking about mostly coming off its literally big clumps that were just sitting on the chrome i don't even know how someone could let this happen but what are ya gonna do. and the bumps under the dirt look silver but i can't really tell if the dirt really messed the chrome up that bad it caused it to bubble up or something which i hope isn't the case. i posted a pic of a clump of dirt that i left so you guys could see but there were even bigger clumps.
