Headlight Lens Cleaning

I just tried the "Deet" method using Off which is 25% Deet. It worked like a charm. I sprayed part of a folded up paper shop towel, wiped the lens, resprayed on another part of the towel and wiped again, then did the same thing for a third time. I washed it, then used a foam pad in a drill to buff with PlasticX. I washed it a second time, and then waxed it with Meguiars. More time and work might have made it look new, but I'm more than happy with the results.
