    Recommendations on removing scratches on headlight lenses

    I'm curious what people are using to polish the plastic headlight lenses... Mine are getting pretty scratched (no clear bra), and I've decided to do something about it. I'm soliciting advice from those who've actually removed scratches from the plastic lenses (front or back).

    My first idea was to use my old standby plastic polish Meguiar's #17. About the only thing I've used it for is removing scratches and hazing from CDs. I tried it on one of the lenses, a bit timidly I admit, without much luck. I don't want to make it worse by fogging the plastic.

    Again, I'm looking for a polish to remove scratches, not just a cleaner...

    Any advice?

    You can do one of the ssr polishes or optimum polishes. As long as the lenses you're trying to clean up are plastic/polycarbonate, and not glass, they'll usually clean up pretty well. You can do so on an Yellow (better for headlights and not tails, as taillights are usually softer) or orange pad (or white if you prefer a lighter cut at first). I've done some lenses with the cordless drill bit attachment. Put the 4" pad on the attachment, then apply a small amount of product to the pad and work it in to the lense.
    If you have a dual action/random orbital machine (or other), you can use that just as effectively.
    Heres some links to check out.
    Attachment and pads:

    polishes:

    You can top it off w/ a sealant to help w/ UV protection too. I'd go optiseal. Its very versatile... use it on lenses, wheels, paint... truly great product.

    zymöl makes a good plastic cleaner. For me, it works better than the Meguiar's stuff. (Meguiar's is good. I use it. I just think the zymöl stuff is better.) I use it on the windscreens of my motorcycles to get rid of scratches.

    Novus polish is incredible and will restore the heaviest of scratches back to a glass finish. See this link:

    Novus Plastic Polish and Plastic Scratch Remover

    It is produced in the US so should be easy for you to get.

    Yep, I forgot about Novus. I've got some in my shop. It's very good.

    Plexus Spray is very good for cleaning off bugs, etc. It won't do anything for scratches because it is non-abrasive.

    You might want to try "Kit Scratch Remover" from your local auto supply store. It's for painted surfaces but I've used it to remove scratches from non-crystal watch faces. Very mild & easy to use by hand.

    Another thought...There are pros who do this sort of clean up. It was a big problem on older VW's where the headlight covers turned yellow with age. I think the cleaning can only be done one time...than it's new covers. Ask your dealer or a body shop.

    I've ordered some Novus 1 & 2 and will report back with the results when I have them.

    Thanks for the suggestions!
