I have read about cleaning them with brake fluid. Have not tried it but I will try it first when need to. Good Luck.
The cloudy headlight is caused by oxidation and uv rays from the sun and a few other factors. Pam is not going to remove any oxidation. The best way is by abrasives that remove the oxidation and then polish. Oxidation of the lens is similar to oxidation of metal only that is called rust and Pam is not going to remove rust. It has to be abraded.
My husband sprayed Pam on ours, then rubbed then with a soft clean cloth, and it cleared them up.
There are several types of kits you can buy from an automotive store. I prefer the 3M kit. In this months issue of Consumer Reports, available at book stores, grocery stores and other locations, they rate several of the kits. A couple of the kits are not worth buying according to Consumer Reports.
