Question

I bought a trumpet two years ago and it is already rusting from inside, what should i do to stop it?

Answer 1

It's probably not rust - just gunk.  If you don't clean it periodically the condensation from your breath (that's what a spit valve's for) will start to produce green gunk.

Take it apart and wash it out.  If that doesn't work - toss the peice of junk and get a new one.

Answer 2

Trumpets are made of brass and not subject to rust.  Check with the manufacturer for cleaning instructions.
