Isopropyl alcohol is widely used to clean tape heads, floppy disk heads and
the like. I've used it in the past to clean vinyl LPs, an idea I got from a
hi-fi magazine. It's excellent at dissolving greasy dirt, but it's always
seemed pretty inert in contact with plastics. I've never tried it on a
mouthpiece, though.
