There is a second problem, though. The stripper may
appear safe when you
use it, but may cause chemical changes in the plastic that make it go
very brittle, or something like that. I've seen a similar effect with
mineral oils on certain plastics. Seems OK for a bit, then it all starts
to fall apart.

Tony is correct, I have a plastic bus pass, it is color printed of
face with name under it printed on it and two blank areas for monthly
stickers to paste on.
Well, one day I tried more harsher chemicals (actone and oils) to get
the gummy ickies off. Actone attacked the prints, and eventually
card started to warp and crack. So I have to handle it gingerly till
after vacation then I'll replace it.
Alochol, ammonia, normal all the way strong soaps is least harsh to
most plastics. I just washed a plastic window (smoker's stained) for
a cd player in warm water and hand soap, came out like new, no new
scratches too! Much easier too.
