      Anybody remove headlights to restore lens?

      Since it's so easy to remove the whole assembly, I thought it would be easier to restore the lens out of the car than taping it off while installed and making a mess with the dust and wet sanding on a freshly detailed car. How would you stabilize the light while working on it? Mine aren't too bad but have to replace a bulb so while it's out I might as well clean it up.

      I sat on the ground and held them in between my thighs while I polished up mine it wasn't the most comfortable way, but it worked! If you can get the projectors out, wipe them down with some rubbing alcohol as well, mine were quite dirty!

      theres a few methods. you can use tooth paste and a microfiber cloth and a bunch of elbow grease or you can use a clay bar kit/ rubber clay bar pad over it with a light dish soap solution. either way leave it installed so you can focus your arm strength on scrubbing and you dont need to tape off anything with these methods as your not using super abrasive materials.

      That's an impressive amount of dirt for a sealed unit

      Use a 3M kit and would have to tape off.

      I need to do this but for the microcracks on the inside of the lense along with cleaning and removing anything built up on the outside. How hard is it to separate the cover from the body the first time?

      not hard at all. set your oven to 350 with the door down and place your headlight facing lens side in - do not set inside the oven only in front. let it sit for a few minutes to loosen the seal then start hacking away at it once it has softened. start to pry the lens from the housing slowly to avoid cracking.
      some people have left the old adhesive on and reused it, i used silicone sealant. while its open you can tinker with painting halos or blacking out the turn signal lens if thats your thing.

      i need to reopen mine and clean the inside as well.

      Use a 3M kit and would have to tape off.
      ok then wrap the housing in a towel and squeeze it between your thighs lens facing up. if you have weak thighs do some squats.

      I have bought a Headlight Restoration Kit off Amazon (2 polishing compounds and UV sealer) and spent about 30mins with drill and polishing wheel attachment. Result was decent, but would be better if I did a proper sanding (only did polishing), did that with headlamps removed.
      I only treated the pvc, the projectors were only dusted so didnt need to polish them.

      I removed the headlight assembly from the car. Clamped on a workbench, I could then us an orbital sander and dual action polisher to access all the edges of the lens. No risk to the paint or grit on the car.
