Used trumpet has some kind of rusting under the keys

++++++

I think its rust or some type of reaction from acid? its moldy looking . Its not a lot. Is there anything I can do or purchase(I'm a poor college student who doesnt have rich parents) to change that appearance?

Try hot 5% citric acid solution,before treatment degrese it with acetone [linked by editor to product info at Rockler]. After treatment rinse it well and dry with paper towels. Good luck!

Moldy looking... green color? I presume your trumpet is brass, this is probably just a little corrosion. Use the search engine on this sight and you can find countless letters on how to clean up brass - they basically breakdown to using some lacquer remover followed by Brasso [linked by editor to product info at Amazon] followed by re-applying the lacquer (although the last step can be skipped).

Good luck!
