Have hard plastic sheet w/ protective paper both sides. How can the adhesive, holding the paper, be removed?

Plastic type is acrylic. Paper comes off leaving adhesive behind.


Have tried: (1) soap and water, (2) Product called OoopsHave hard plastic sheet w/ protective paper both sides. How can the adhesive, holding the paper, be removed?
Honestly, I don't know, however, I wanted to give you a warning. I tried to clean up some acrylic with Goof Off one time and it ended up cracking it, so be careful what you experiment with.Have hard plastic sheet w/ protective paper both sides. How can the adhesive, holding the paper, be removed?
If this is a new sheet of plastic, then the paper%26amp; adhesive will come off together -------- HOWEVER if not new or if it has gotten wet then start over with a new sheet, I've never been able to sucessfully remove the mess. If you bought it as new and this has happened then take it back to the supplier.
Honestly, the adhesive film should just peel up with the paper. Can you gouge the film in an inconspicuous spot to try and get under it to peel it up? Sometimes, depending on how the acrylic is cut, it can be really hard to grab the film.
