Foggy headlights

[Canary2323]

It's not for my trailblazer buy actually for my other car lexus is300 the wife took it over since I got the tb. Drove the other day and could barley see out headlights ams noticed they were all fogged up. Tried a number of products, none seemed to work. Last one I tried was plastx by mothers, any have any good products or suggestions how to get them clear.? Thanks

If chemicals and polishes don't work, go with some sandpaper and muscle through the oxidation. Once you get down to the lens itself, use finer grits to smooth out your scratches, and then you'll get to where you wanna be.

The question lies in this: Is the fog on the inside or out?

Inside:
Take out the bulbs and stick a hair dryer blowing into the open sockets to get the moisture out. No more fog inside. Should take about 45 minutes to an hour so don't run too high heat.

Outside:
Rubbing compound has always worked for me. Get the lens wet, put some compound on a paper towel, and work it in. Get a wet paper towel after some 5-10 minutes of elbow grease and compound, and wipe it all off. Should be better after that.

Good luck!

What are suggestions on sandpaper grit? Doesn't look like it's on the inside but it's directly in front of hids.

I used this kit:

Buy 3M Headlight Lens Restoration System, 4 Per Case 39008 at Advance Auto Parts

It comes with 800, and 1000 grit sand paper disks and a 1200 grit foam pad. It didn't quite cut through as well as I had hoped, I wanted to use something more rough, so maybe go with something lower. It all depends on how bad yours are, mine were pretty crusty. They didn't come out perfect, but they were good enough. (they are the ones seen in the Clear Corners article)

Look on youtube for toothpaste headlight cleaner.

Those lights look good, and I need some of those clear corner lights.
Tried the toothpaste seemed like it worked Ok but now there foggy again.

Thanks, some parts have fogged up a lil bit again. Gonna try to resand them at some point. Hope to get them nice and clear again.

After polishing spray clear coat on them to help protect against further UV and oxidation

So it looks like the foggyness is on the inside, so not sure how to handle it now. I read your not supposed break the seals on the light s?

when you sand/polish them, I would look into the 3m protective film for them
considering how much $ I'm putting into my retrofit (I'm sure the few others that are doing the same will agree lol) I'm taking NO chances, and gonna protect my babies as much as possible
easy to install, works wonders, and completely reversible, renewable

Depending on how bad the oxidation/fogging is and the condition of the headlights, I would start by wet sanding with 1000 grit, followed by 1500, then 2000. After sanding you can go with a light buffing compound and then finish up with a polish.
