We have a '96 Mustang GT, and the headlights now have a thick cloudy appearance, not the clear transparent appearance I prefer. My uncle told me a while back that companies produce cleaners to remove the filmy appearance of headlights, but I can't remember any specific cleaners he mentioned. I was wondering if anyone knew of a headlight cleaner that works, and which would be the best, or best value headlight cleaner. Do they all work pretty much with the same outcome, or are some better than others?
