How to restore a poly windshield

I have a hazy windshield on my rzr and would like to know what to do to get it clear again anyone have a method that works?

Learning lessons from years ago, I only use Plexus Plastic Cleaner Protectant and Polish.  You use be able to get it at dealers.  If you used an alcohol based cleaner, it might have ruined your windsheild.  I use it just before rides when the windshield is clean.  I use two soft cloth rags on it.  One to get the polish/cleaner most of the way off, the other to final getting it off. Mud and dust will not stick to your windshield once it is on.

Thanks Les

I ordered a flip up windshield from SuperATV ( hard coated inside and out) . I intend to carefully maintain it using Gimpy”s plexus method.

Clean with soap and water when washing. Let dry, then coat it with Plexus.
