I used a product called Flitz. They have a diffrent polish or cleaning compound for diffrent types of materials. My headlights were hazed over really bad when I got the car. Its going to get new light assy,s soon but car needs painted. Iam not changing them until then. Flitz has a polish for plastic that took 90% of the haze off my lens. Not 100% but helped alot. Hope this helps.
