    What causes headlight lens to become foggy or bleached looking? And how do you restore the clearness?

    I suppose you are referring to the "new" plastic lenses now popular since, I suppose the late 80's? Sun, age, internal heat from the bulb, road grit sandblasting the lens as you drive.... I have heard there is some potion sold at various auto parts places to restore the clarity-have no idea if it is any good. I would think a trip to the local airfield might yield some results-they face the same dilemna on a larger scale. Makes a great case for glass headlamps.....Luck, Dan

    You can use some buffing or polishing compound to smooth the outside, but there is usually dmamge on the inside too. If it is too bad, you might try going to the junkyard to see if you can get some replacements.

    there are a couple ways to fix it. go in a autozone and look under the Permatex silicone display and on the bottom shelf there is one kit with a compound and polisher in it. Or go over to the paint section and look on the third shels and there is a buffing apparatus you put on a drill. Both of these work and are pretty cheap.

    Last time I priced a used junkyard healdlight assembly they wanted more than what I coulg get a new one for through Advance or Auto Zone. And some wanted me to buy the whole header for like 300 bucks and wouldnt part with just a headlamp assembly.

    Let me know what kinda car you got and I can give you a price within a couple minutes of reading it.

    Do a search in this forum as there was recently a long thread about this topic.
    Auto parts and auto body supply stores have compaounds and kits to help this problem as it's very common.

    I had a clear dash once that was completely fogged up and I couldn't read the speedometer. I removed the clear plastic lens and polished it using toothpase. This worked really well, did take some effort though. I never did have any other issues with the lens after that.

    I believe it was just regulear Crest

    I had this problem on a Ford Escort and finally with to a junkyard and had to buy the whole assembly, and as was stated above, the cost was more than new one at autozone. I am now havin this problem on Chev truck, will try the polish and buff idea. Will let yah know how it turns out. Thanks for the advice
