I am trying to get rid of the yellowish buildup on my headlight which made is making my light unclear. I saw several wet sanding applications that claim to remove the residue, but does it actually work, and which one is the best?

 

yes, it really works... as far as the best: its just sandpaper

 

i tried it on mine it seemed to help but then it came back an they look like **** again, i am just gonna buy some new head lights

 

I have the same thing on one of my headlights. It's like a scuffed up look. Hard to describe. I think that's the same thing he has. So naturaly, I want to get this off of mine.

What grit of sandpaper is reccomended?

 

You have to polish them after sanding, with a plastics polish, preferably from meiguiars or 3m

 

gritty toothpaste is supposed to work as well. i haven't tried it myself though

 

wet sand from about 800 to 2000, or thats what i did, it may not take that much. start higher if it works.i mean if 1500 will get it out, thats lesssanding for you. then 3m rubbing compound a few times. buff it, then a layer of regular car wax. good as new.

 

Whatever you do
DO NOT SAND IN CIRCLES!!
You will make your headlights worse!

 

i had this problem hardcore on my car....what i did was bought a kit from autozone that somewhat worked but not too well....i then bought some sandpaper as said in another post and some scratch x from meguiers and i dunno if i was doing it wrong or what happened but that didnt do anything...then i bought a kit in walmart it was in a bag that was shiny and it was the same set up as the first kit but it worked great....my headlights looked brand new...now when i clean my car i use the scratch x on my lights and they look great...

 

Did this on my lights. Got a kit from Advance Auto Parts with 1k, 1500, 2k, and 2500 grit. And yes, don't sand in circles. It had instructions on what to do, and it had a polish.

It's around 5 or 6 months later and they are starting to fade again, but it's definitely worth just 20 bucks to delay spending big money on anything else.
