Cloudy Yellowed Headlights

Does anyone know how to clean the lens on headlights that have yellowed? I think they are plastic, someone told me brake cleaner?
Thanks

Get some MaGuires PlastX at a auto store. I used this and a rag and cleaned my headlights right up. Sometimes, the lights are to far gone and need to be replaced.

What year and model vehicle?
The different makers used different materials over the years
The process can be different depending

I've been using a product that Wally World carries called CCP 5 minute headlight lens restorer. Consists of several chemically-impregnated pads that chuck into a drill. You damper slightly and buff away. Works extrmely well on taking out scratches and cloudiness. Not sure how it will do on yellowing.

Is that for the newer 'clear' headlights TG?

Or the late '80s early '90s Lexan headlights-those get real yellow
I use a wet-sand and metal polish combo on those

Seems to work on both, but I haven't tried it on anything that was badly yellowed, only cloudy/hazy.

Restoring Lexan Headlights

"1993 mercury villager"

Hmm...I'm pretty sure those are the lexan type that get really yellow

The best, safest way, is to start with the least amount of abrasives
Perhaps the other suggestion here may work

If they don't, or you know for sure they are really bad, you may need to get medieval on them

Restoring Lexan Headlights:
First wet sand with 600 grit sandpaper
About 10 mins. each one
Then wet sand with some 1200 or 1500 grit
10 mins. each
Then polish with Autosol (I've heard mothers metal polish and others work well too, but I've only used Autosol)
Rub it in, let it dry, then buff it off with a buffing wheel

If it's on the car you can get a buffing wheel to go on a drill
Also be sure to tape off the paint-you don't want to sand that
Off the car- a buffer and plastic compound works wonders

I have used this process many times with great results, but mostly on slightly older models where the lexan turned almost biege/brown (think '93 and earlier)

Pic link enclosed

I am including pictures of the front headlights for you to see maybe that will give a better idea of the yellowing and condensation in the lamps.
Thanks for all your imputs and replies.

Thanks For The Pics, That Really Helps

Yup
Those are them
You might try just the polish suggestions
It might work

I'd say from the pics, they will probably need the wet sanding though
And the condensation concerns me

It's going to be a bit of a project, and there are tools (a cordless drill, a buffing attachment) and materials (the good polishes aren't cheap) required
...and a steady hand as to not ruin the glass or car finish

You might want to price out replacement headlights (glass-not the lamps/bulbs)
As I don't think they will be rare or expensive (as far as those things go)
It may be worth it for new ones

IMO there's no need to go to the dealer on these, if you can find them at a local parts place at a reasonable price

=========================

I would have thought the same thing until I needed to replace a light on the wifes 2000 Grand Prix.

the dealership was quite a bit cheaper than Advance Auto Parts.

BTW; not all dealerships charge the same price for the parts. I have seen large differences between different dealership parts departments.

a few phone calls could save you quite a bit of change.

Sounds about right
Dealer list is $200....maybe you could get them for 150

Those are pretty common and are made by the after market
The more uncommon parts aren't, and A/Z, Adv, NAPA, et al. simply buy the dealer parts, mark them up, and sell those

Nap's Wife's Grand Prix must have been a one-year wonder (style only used for one or two years), or only used for the Grand Prix alone (most lights and such are found on many models)

Good point though, one should always check

Thanks

Thankyou to everyone for your posts, I will do some calling to see what kind of deal I can get from local auto parts suppliers, I may even check the auto wreckers to see if they have any. Will post back with the cost.
Thanks again......
