Help removing paper from plexiglass

[Jester1167]

We use an old core too. Its a pain to get old plex started but once you do it's a breeze.

I'll have to try the paint thinner trick on the really bad stuff.

We use an old core to remove all masking off plex, aluminum whatever. The mineral spirits works great. Here is a tip, do not store your substrates with masking on them any place the sun can shine directly on them. That makes removal super hard if the sun baked it on.
