Toothpaste, elbow grease (or a drill with a polisher bit) and an hour spare

Did mine with this by chance and I couldn't believe how good the results were
I used it with the G3 detailing lubricant

The 3M kit is even better Harry. I've tried them both.

I would say I'm 75% happy with the Meguiars kit, it really did make a difference. I'll get the 3M one and give it a blast too. Won't do any harm.
There is a guy with an R230 that drops off his kids at school same time as me. His lights are misty too. I'll stop him one morning for a chat.

Headlights on my ML (W163) were cloudy - but I found new replacement ones for £70 each which did the job perfectly.

Cloudy headlights even more prevalent on the med coast of Spain - where there are specialist mobile repair franchises doing a fix. I am told that once polished back, the cloudiness returns fairly soon and needs polishing every couple of years - but I am not sure how true this is.

A bodyshop can also mop the lens back to neat new condition in a short time for a small outlay. If you're not DIY minded, that might be another option.

Once polished the lens need treating with clearcoat lacquer to stop the UV rays doing the same again.

I have just done the offside fog light on my S320 I needed to do it as I have replaced the nearside one with a new one ,and this made the offside look a bit tired,all the muck which was mostly grime and salt with toothpaste and hot water and elbow grease,it has come up well

Aha! That's what's going wrong.

Rubbing compound and electric orbital polisher-did my mums (Co)modus this very morning , then a coating of carnauba wax . Did other cars this way and lasted well.

500 grit wet & dry Then 1000 grit wet & dry Followed by 2000 grit wet & dry And quick polish with t/cut or compound Then finally a quick coat of wax....... Works every time 100% guaranteed results

I thought that was for glass headlights ?

Not sure? I've done it on a few previous cars of mine and can't remember what type of headlights they were, I definitely remember doing it to an xr3i, they would've been plastic

 

[mjc1]

will any of the cleaning products effect the lens?
