My car's plastic headlight lens have become so dull due to the effects of oxidation that they became translucent. I could no longer see the headlight bulbs or its reflectors. So, I went to my nearby auto parts store and purchased a Headlight Restoration Kit to repair the problem. After following the kit manufacturer's directions three times, I was not satisfied with the final results of my efforts. I made up my mind to accept the expense to replace both headlights. Weeks later, I got the idea to try that stuff I had on hand, Bring It On. It can't hurt, right. After all, I intend to replace the lamps anyhow. After applying Bring It On Cleaner just one time, as directed, Bring It On Cleaner removed that unwanted oxidation from the plastic lens. The headlight lens then became transparent. I could then see the bulb and it's reflector. Of course, I was so happy that I immediately started work on the other headlight and I was just as pleased of the final results that I accomplished using Bring It On Cleaner. Now I don't have to buy a new set of headlights. Thank you, for a product that really works well.
