Clear plastic can scratch easily when cleaning it. This guide is about cleaning plexiglass.
What is the product that cleans plexiglass shower doors?
Sounds strange but I use WD-40. I wash the doors and dry with an old rag. Then spray with WD 40 and they shine like new. Hope it works for you as well.
I have a desk lamp that has plexiglass. What is the best cleaning method to get the sparkle back to brighten the light?

Find a hobby store. You can buy plastic rubbing compound or scratch remover. It works like sandpaper for plastic. I used it to restore the shine to my car headlights.
