Not exactly a bass question but close enough. My brother has acquired a fiddle that someone decided to color with blue food coloring--we're talking a lovely shade of robin's egg blue. It may have penetrated pretty deeply into the wood itself. The thing sounds pretty good but looks hideous. Since I am sort of a journeyman woodworker, he has talked to me about returning it to its natural state. Unfortunately I have absolutely no idea about this. Anybody ever removed food coloring from an instrument? If so, how? If not, what do you think?
