Help...Foam Stuck to Brass

Any good ideas for removing foam stuck to brass? Goo Be Gone & paint thinner not doing a thing! Is it safe to use a Dremmel and a wire brush? Anyone found any other good ideas?

What type of foam is stuck to the brass? If it is polystyrene, lacquer thinner (not paint thinner) or toluene should work.

The foam is the type that came in the boxes a ALCO brass model would come in.
