Answer # 1:
Here are a couple of ideas:
1. Spray a small amount of stripper (try both ammoniated and non-ammoniated) on an area the size of a quarter, let it dwell for 10 minutes (keep it moist) and then use water pressure or dry vapor to remove it. If this doesn't work try a spray of technical ammonia. All of these may damage the surface so test in a very small area first to see how the plastic responds to each product and process. Do your tests in an out of the way location and keep the test area to the size of a cotton swab and nobody will notice. If you find something that works, try a larger area.
2. Winsol Labs make a puck mark remove for hockey rinks, you might see if they will send you a sample. Visit: www.winsol.com
Let us know how it goes and best of luck.

Answer # 2:
Plexiglas® is an acrylic and is therefore sensitive to ammonia, which is a common ingredient in floor stripper. Some household cleaners also contain ammonia and will damage the panels. Since you already have stripper solution dried onto the panels, you may already have damage. First, try a mild solution of dish detergent and warm water to see if the spatter will come off. If that fails, try a solution of a non-ammoniated stripper to remove the buildup and see if any harm has been done. Use it on a small section as a trial.
Avoid scrapers that may scratch the surface.
A product called Novus is recommended by the plastics people for cleaning and polishing Plexiglas®. Check the Internet for a source.
