Ricko Posted March 25, 2018 Report Share Posted March 25, 2018 Hi, has anybody managed to restore fogged headlights? Cheers Quote Link to comment Share on other sites More sharing options...
matgriff Posted March 25, 2018 Report Share Posted March 25, 2018 Hi, if you mean the plastic lenses have gone milky, then just buy the autoglym headlight restoring kit, works great, bit messy but brings them up like new. Quote Link to comment Share on other sites More sharing options...

johnnytheboy Posted March 25, 2018 Report Share Posted March 25, 2018 Try polishing them, it brings them up ok, or you can sand them down and spray them with a special clear coat if this doesn’t work! Quote Link to comment Share on other sites More sharing options...
Wb123 Posted March 25, 2018 Report Share Posted March 25, 2018 I used to have a set that filled up with condensation, had to take the bulbs out and hairdryer them before each mot. Quote Link to comment Share on other sites More sharing options...
bruno22rf Posted March 26, 2018 Report Share Posted March 26, 2018 Most car detailers do it for around £25/lens - mine looked like new when finished and were virtually opaque when he started although it took nearly an hour to finish the job.

Rewulf Posted March 26, 2018 Report Share Posted March 26, 2018 I do this quite often. A rotary polishing machine and a fairly aggressive polishing compound like fareclas g3 or g6, DO NOT USE ONE WITH AMMONIA ! ie TCUT. A steady slow speed, dont get it hot enough to melt your headlight, will definitely yield improvements. If they are really bad, a light nib with 12-1500 grit paper first. You will probably find they go back opaque after a few months anyway, so an investment in the polisher ect, isnt that bad an idea. Plus you can use it on the car body.

Proper glass headlights are not affected. Not all plastic ones are strangely, but high UV levels seem to play a part. I have a friend in Oz who has a business cleaning them up, as its so common in the hotter areas. Quote Link to comment Share on other sites More sharing options...
Vince Green Posted March 26, 2018 Report Share Posted March 26, 2018 (edited) Mercs do it a lot, the halogen bulbs cook the plastic, some 3000 w+d plus compound works a treat. Silicon tyre/rubber spray improves appearance short term Edited March 26, 2018 by Vince Green Quote Link to comment Share on other sites More sharing options...

Dunkield Posted March 27, 2018 Report Share Posted March 27, 2018 I have done Micra ones and they came out well. You can either buy a kit or just use the finest w&d you can find and then finish with polish. Interesting to read comments about T Cut because I am fairly sure that is what I used.

The ammonia can burn the plastic ,staining it, if you leave it on too long. Quote Link to comment Share on other sites More sharing options...

Are they not still hazy underneath ? Ive never tried that to be honest, I would have thought the heat, stone chips ect would decay the lacquer pretty quick, what brand are you using ?

If the lights are ancient ot really yellow it can be harder but the keys wet flatting the dead plastic off. Quote Link to comment Share on other sites More sharing options...
