tried to find the threads talkin' about cleaning up those UV dmaged plastic headlight lenses. There are a coupla proprietary kits likeTurtle Wax etc. Had a demo of a US made waterless car wash in a pressure pack containing Canuba wax on the RHS and JIF lemon scented and soft sponge on the LHS. Both came up looking tops and rego passable in minutes and no effort :D

think Gumption may be bit too abrasive, but just more work to restore to new if so - takes back to ancient practice of plastics classroom - Brasso and 1000 grit wet and dry

Most auto shops sell a cleaner/polish that fixes cloudy headlights now,around $20 I think.

Try this stuff.. IMO its the best but I'm sure there is plenty out there. My H6 Outback headlights still look like I did them yesterday.

It's just polishing, you could most likely get a similar result from the high grit papers first, then some polishing compound safe for plastics. I sometimes polish rough machined steel press tool dies at work to an almost mirror finish with just stones and paper ;)

The kit comes with all the stuff and there is a stage 1 (course) sandpaper, then a stage 2 (fine) sandpaper and then some polish but the big key is the plastic protectant that is applied and the end, this is what keeps it turn back to shite and until this is applied (even after polishing) the still look like crap. I'm really impressed by this stuff and it takes a lot to impress me ;)

Thought I'd add the JIF method to save the $pend

Corr, customer fronts up at mates shop with some Japanese manufacturer dealer quotes, part of one is to replace the headlight assy due to lens not able to be cleaned - so fork out almost six big notes.

No jif (lemon or otherwise) under the sink so old fashioned Brasso up first for about three goes, then another three rubs of "appointed to her majesty" glass polish - and mate looks like a newie :D

And then you would need to put an protector on the top to prevent from yellowing, I think its UV protector something... anyone?

The cheapest & most effective product I've used is acetone, bloody brilliant. You need to be quick & not let it sit for very long as it can melt plastics. also follow the safety instructions re' long term exposure, decontamination & no naked flames or sparks- Goes boom realy well. PS do not use it to clean a telephone!

I have used proprietry cleaners, took hours but a good job, then got smart and used Mothers aluminium polish. Cleaned both lenses in about 5 minutes and the job is just as good as the $20 touch. I just did the wifes 2001 Mazda. It was real bad so gave it two polishes. They now look like new.
