Greg This is your opportunity to do some research, courtesy of the school district.??Leave everything alone, take some pictures and?make?notes, and when the springs and centers start to misbehave, you'll have a terrific article for the Journal, complete with factual information.

I'm assuming the icing is the standard vegetable shortening and sugar. I found the dry, crusty remains of some sort of baked good with said icing in a school console piano. I'm wondering if all greasy parts need to be washed with naptha, or if the vanilla "lube" with sprinkles is harmless? The surface solids have already been removed. All that remains is some soaked-in grease on about 10 damper flanges and levers. I'm just wondering if the springs will start breaking off and action centers will start freezing up. Maybe I'll leave it as a long-term test specimen. Greg Graham -------------- next part -------------- An HTML attachment was scrubbed...
