I like to use, Isopropal alchol, on Poly finishes. It's what they use at the factory in Vienna. Works very good. Sometimes when I find a "goober" that doen't repond...gues what..the indudtrial cleaner, warm water. I think some "goobers" are oil based, which cleans well with Isopropal, but if sugar "goobers" water really does the trick. (small amount of soap, and don't get careles with "any" fuilds around a piano. and make sure you know absolutly what type of finish yu are dealing with, or part(s) as the case may be. Once I tied to clean a sounding board, (all the strings out of course) and I had this one spot that nothing in my arsinal would dissolve. I think it was a Pepsi, but I didn't taste it ..could have been coke!....anyway..warm water took it off like Mr. Clean....Just gotta test a few things see what works...and doesn't damage. Gregory
