Things You'll Need

  • Rubber Gloves

  • Stir Stick

  • Rag

  • White Vinegar

  • Ammonia

  • Spray Bottle

  • Small Bucket

  • Rubber Putty Knife

Step 1

Chip off loose paint with a rubber putty knife. Do not use a plastic or metal putty knife, because these might scratch the plexiglass. Plexiglass surfaces are very slick, and paint has trouble sticking to slick surfaces. Acrylic paint chips off relatively easily.

Step 2

Put on rubber gloves.

Step 3

Combine equal amounts of ammonia and white vinegar in a small bucket. If you are unable to get all the paint off the plexiglass using the rubber putty knife, the ammonia-vinegar mixture can loosen the rest. Chemical paint removers are not recommended, because they can warp plexiglass.
