Re: CLEANING Headlight Plastics
For years I've used ArmorAll because it makes it easier to remove squashed bugs. Lately I've started to use a high quality car wax instead. In either case, headlights are very clear/clean. I do the same for my roadster (and the headlights look brand new) as for my 2003 A6 with 164k miles (and the headlights are still clear with no haze).
