Headlights???
Get an SOS Pad, windex, a rag and a water hose. Put toothpaste on the SOS Pad, and spray the headlight with windex. Scrub the headlight hard with the SOS pad in small circular motions. Put some elbow grease into it. Then let it sit for about 5 to 10 minutes and spray more windex, then scrub some more. Rinse off with the hose. I did this and no more yellow plastic, they're just as clear as can be.
Uhhhhh.....No.........sorry, but an sos pad is too course. Very fine steel wool, 1200 followed by 2000 grit sand paper. Sos pads have no quality control for fine gauge wool and can damage plastic. Might have worked once, but is not a good idea. Sorry.
