How to get rid of yellow glaze on headlights?
 

My brother has a 06 cayenne.! Everything looks superbly fine, but I have noticed some cloudy appearance on the headlights. I think it is caused by oxidization and road grime build-up. Can someone tell me a good product to use on headlights to prevent clouding of the lenses without risking damage to the protective ultra violet layer. I have read that regular cleanings with a car wax will prevent. Please recommend a good products that you have found to work for you. Hope to check out JC Whitney this weekend to pick some good product to perform this task.

Any recommendation?

I have also experienced that situation, maybe its condensation, or maybe the type of your headlights has polycarbonate lenses. There's an expensive way to get rid of that junky ones. So, try removing this fog and spell out damaged lenses with minimum cost and effort by using Diamondite, Wolfgang, and Plexus. Hope it can least for your cost and effort so that replacement headlights can be avoided.
