Obviously start on an obscure part to learn how, but there are plastic polishes for PlexiGlass, acrylic, acetate, butyl acetate and similar plastics. Follow the instructions, and do NOT allow it to get gooey or dry - will scratch easier - needs to stay moist while polishing, and NEVER use straight strokes - use random circular pattern.

DuPont plastic polish is more aggressive - i would use it for light scratches orpretty well hazed up areas, lightly scratched or basically just fogged surfaces I have found Novus plastic polish to work better.

On an aquarium, be sure to back up the glass with your other hand while working, to prevent cracking or loosening up the sealant at the edges/corners/base. You do not need to,or want, to push hard oryou will cause scratches - a light polishing motion like you would use to clean a window or mirror is what you want, and periodically clean it off to inspect and remove excess grit. Several passes will give a much nicer finish than one intensive session.

NOTE - be sure your acrylic does not have a tinted surface - that cannot be successfully polished, only cleaned with a mild soap like Dawn.
