An amazing product recently caught my attention.  It's called "Simply
Wipe" and is formulated, according to the label, to remove spray mount,
tape residue, rubber cement, decoupage glues and varnish.

I've used these paper towelettes to remove gummy residue from labels
on glass and plastic containers, and it works like a charm.  It should
work equally well on celluloid piano keys.  It's made in Israel for

We bought ours at Big Lots, but craft stores like Hobby Lobby should
carry it as well.
