Yesterday I was about to toss all the Plexi scraps I have because the paper
backing is stuck on so tight it can't be peeled off. I decided to try
laquer thinner, assuming it was going to melt the plexiglass since they were
headed for the trash anyway.

I moistened a paper towel with it, place it on the paper backing and a few
minutes later it had softened the backing enough so that I could peel it
free (with a bit of work - the scraps are probably 25 years old).

Have you tried a heat gun?


wouldn't it be tricky to not melt the plexi too?

i know acetone will fog plexi, and ammonia products can lead to
microfractures.
