[CAUT] Yamaha sharps

[Fred Sturm]

	Yesterday I had an unfortunate experience cleaning keytops. Yamaha  
C-2 about 20 years old. The sharps (wooden) had a good bit of buildup  
of the gray goo, so I was fairly liberal with the Cory KeyBrite. Got  
done, looked back to admire my work, and found it had raised a very  
thin clear finish on the sharps - blistered so as to look somewhat  
white.
	Has anyone been down this road and found a good fix? I'm thinking I  
have to remove this light, glossy, clear finish, and don't want to  
disturb what's underneath. I'm assuming that this is probably not real  
ebony, and that even if it is, it has a black spray coating of some  
sort. I thought of just buffing with 0000 wool, and emulated that with  
a square of ScotchBrite I had handy. Doesn't seem like a good way to  
go. So I am thinking I'll either experiment with solvents (possibly  
spray a solvent in hopes of re-amalgamating - foolish hope) or sand  
carefully. But perhaps someone has come up with a better plan.
