I clean mine once a year cuz that yellow ish keeps coming back. I use rain-x polish, plastic polish and cotton cloth. Gotta rub it really hard like on a friday night. I did few sets by sanding and it worked, just takes patience.

 

Im gonna try what the link said. Il post results, my lights have a lot of haze

 

I've used the 3M kits on a few of my cars and have always been pleased with the results. First few times I used the drill version and most recently I used a new manual version (no tools needed). My headlights looked like new every time. I even used it to clean this horrible spray tint the previous owner put on the tails of my is300. The kit is only like $20-25 at advance (and probably any auto parts store).

 

Wet sand, buff, and polish.

 

I used the turtle wax kit. Comes with a rubbing compound, 4 grades of sandpaper, a sanding lubricant and a uv Coating wipe. There was enough stuff to do both headlights and both tail lights. There's only 2 wipes but wipe a headlight then flip the wipe over and give the Tail Light quick wipe too.

 

Cleaning lights is always the easy part. If they aren't sealed though you are destined to repeat the process over and over again. There are guys out there that can do a 3M finish over them once polished or there are products like ReNuLite that can be sprayed on and provide a final seal. I've used that product. It's UV activated and actually cures on the light to provide a protective barrier. I'm sure there are others out there.

 

Whether you need to do wet sanding or just use a buffing compound all depends on how bad the headlights are clouded. I was able to use just a buffing compound and a buffing pad on my drill.

I took my headlights out of the car and it made it a lot easier because I didn't have to worry about hitting the body with the polisher.

Then what is probably the most important part, coating the polished headlamps. Using a UV resistant/stabilized product is important. Otherwise the coating itself will turn yellow. And having the headlight out of the car allowed me to use a spray coating without any worries.

 

if they're real bad you'll need to wet sand.
if they're on their way to real bad you should be able to get away with a high speed polish using a good quality plastic polish or tape it off and use brasso (use with caution).
i've had good results with mag wheel polish as well.

i usually polish/seal mine every 2-3 months and seal every few weeks to keep them clear. its an uphill battle as they age.

wetsanding requires patience though so take your time either way.
i actually just did mine last night as they were yellowing as i've not sealed them in 3 months. came out fantastic, as usual. I like and use the blue magic headlight polish religiously on mine and customer's cars.
good luck.

 

Great suggestions. But there has only been one thing that I've found to work long term. If the headlights are yellowed, 3M kit is fine. If has a deep and significant yellow damage, then you will need to go one or two steps more course on the sandpaper to start. Then work you work way through the 3M kit.

In either case, the only way to prevent it from re-yellowing is to let the lights dry. Wipe them thoroughly clean. Then put two good coats of clear on them. After 2-4 days of drying, then apply UV polish - either what come with the 3M kit or my preference of Plast-x. Re-apply Plast-x every 3-4 months or best judgement given how much lights are subjected to direct sunlight.

I used a 3M kit roughly every 4-6 months until I re-clear coated them. That was now a year ago and no signs of needing to redo.

It's $16 bucks at courtesynissan so i bought four on my last visit . Compared to $28 at the local parts store it was a no brainer.
you'll just need the uv coating
