    What do you chaps find the best way to cure the cloudy headlight problem? I have tried all sorts, but it just seems to come back again! The fixes I have used are all very labour intensive too, loads of time spend rubbing and polishing, generally for not that much of an improvement!!

    The 3M kit does work, but I am wary of using that regularly, and it is safer taking the light out to do it rather than risk the paintwork.

    I haven't resorted (yet!) to trying Arm and Hammer toothpaste, any demon recommendations other than that??

    Thanks Bishbosh, very interesting reading! What you did, although the end result was worth it, did sound like great deal of effort was required to finally achieve it. It sounds a little like the 3M cleaning and polishing method, only better!! Having used 3M, I did find it quite effective, and it did improve my lights significantly.Not as good as your end result however!

    At the end of the day, either the light manufacturers need to design the lights, so that the lenses can be replaced - without the need to replace the whole headlamp, or else they ought to come up with a decent easy to use polish that actually works.

    To be fair my headlight lenses were pock marked and really needed a good refurbish. If it's just a bit of cloudiness then just a buff with a rotary polisher might suffice.

    I suspect that the cloudiness could be the plastic breaking down in the presence of UV rays. Especially if polishing the lenses has removed the UV coating.
