So I heard about this trick yesterday, and had to try it on my daughter's car
Tools required for headlight restoration:
#1 - soft cloth or paper towel (I used paper towel)
#2 - can of Deep Woods Off insect repellent
#3 - Windex
Steps to restore hazed headlight:
#1 - spray some bug spray on a paper towel, enough to saturate it a bit
#2 - wipe it *briskly* on the headlight, rubbing it in pretty good
#3 - *quickly* wipe clean, don't let the bug spray stay on the headlight for a long time, or it can melt the plastic!
#4 - spray it with Windex and wipe down with a clean paper towel to remove residual bug spray
Don't know how long the results last, but it took less than a minute per headlight, and you can see the difference it made! It actually took off the layer of haze, the paper towel was brown.
