<html> <body> What I do (adapting an idea from Steve Brady) is to take a real beeswax candle, and make a short mark on each key, then smear it around until it "disappears" into an even trace layer all over the key, using my fingers and a shop towel. You can try varying amounts of wax, and have the pianist try them out. I don't bother with any "product" for cleaning. I just wet the corner of a shop towel, squeeze it into the rest so it's barely damp, and clean off only the visible dirt. Using minimal water seems to help keep the keys from being slick afterwards.  I've found that pianists are most bothered by slick sharps, which they can slide off of. I like the beeswax because it is easy to keep in the kit, has a pleasant odor, is completely nontoxic, and could be removed if need be. It gives just enough stickiness, without any visible changes.

And they were dirty too. I cleaned them with “Keybrite”, and now they’re even more “slick”. Any quick solutions? (Light sanding? Hairspray?)   Thanks,   Jim Busby BYU   p.s. I couldn’t find anything for ivory on the archives. </blockquote></body> </html>
