[pianotech] permanent marker

[John Formsma]

I remember the thread also. Seems like permanent marker on plastic might
not be too hopeful...but you can try:

Flitz polish
Goof-off
Rubbing compounds of various abrasives
Sandpapers of various abrasives

Worst case scenario, just recover the keys (or have it done). Plenty of
folks advertise for this in the Journal. Might end up being cheaper to
recover rather than spend hours trying to sand, rub, polish 52 times. I'd
take two of the worst keys, hit them with 600 or 800 grit sandpaper, and
see how much comes off. Continue until you get to your desired sheen. See
how long that takes, multiply by 26, and you'll know roughly what you're
into.

Ron Nossaman leaves his white keys at 600 grit sheen, which feels good.
Surprisingly. (Correct me if I'm wrong about the grit, Ron.)

Or, get some white sharps and make all the whites black, like a
harpsichord. ;-)
