Hi
Just wondering what's the best way to clean the plastic headlight cases please? Mine have become quite foggy and I'm sure it's affecting my vision at night.
I have got lights that flicker when they come on and go really bright (I'm so not technically minded and don't know the name of these type of lights lol).
Thanks in advance
The best way will depend on what you have available to you. If you have an abrasive polish like Brasso, T-cut, paint rubbing compound(G3, G10 etc) or similar in the house, then use that. It will take a bit of effort, and possibly a couple of goes, but will do the job. Toothpaste is a
very fine abrasive paste, so will work but is a lot of effort. Otherwise one of the headlight restoration kits would be the way to go. These are an expensive way to buy a commonly available abrasive in a pretty package. If your lights are really bad, then they(and your arm muscles!) will benefit from using some fine wet&dry paper first. You'll be looking for a couple of sheets of at least 1000grit used very wet to avoid badly scratching the lens. If you have experience of flatting and polishing paint then using coarser abrasives or powertools is worth considering.
Mine were very rough and opaque; a couple of applications of Farecla G3 rubbing compound(coarse paste used for refreshing tired paint) brought them back to clear in about 10minutes and with minimal effort. I used coarse G3 simply because I had it in stock, I would have bought G10. Using powertools on plastic requires real care to be taken to avoid melting the surface; doing it by hand is much less risky. And at least a headlight isn't a big area.
