frozen slide and piston felt

I borrowed a 4 valve piston tuba from my sons high school for several week. The first thing I did was give it a good bath. I was able to get everything moving except for the 2nd valve slide. It is frozen. I tried tapping lightly as well as using a hair dryer for direct heat, but it will not budge.

Any ideas?

The valves are also somewhat noisy because the felt has been so compressed. Is there a special felt used for pistons? or could I get a good quatity craft felt?
