Do not use denatured alcohal to soak off paper from Plexiglas. I've had it
craze very badly from exposure to alchol. I had a Plexiglass cylinder that
some one filled with ethonal, and in a short time it fractured all over
and
fell apart.

Rubbing alcohol is methanol. Big difference from ethanol. That said, I
have no idea if methanol will harm plexi.
