Here is a quick little process I did to get the yellow haze off of my headlights and fog lights.
(Notice there is a lot of plastic shavings in there from drilling out the holes for the parking lights)
(I need to take these back out and use the PB Blaster to loosen those rusted screws)
(So I can bake 'em, take 'em apart, and clean all of that plastic out of there)
