Before we go through the steps we need these:

  • Water spray
  • Microfiber Towel
  • Compound
  • Car Polish
  • Metal Polish
  • Wet & Dry Sandpaper with Different Grip Sizes
  • Foam Backing Pad
  • Headlight Polishing Kit (Wool Pad, Foam Pad & Sand Paper)
  • Drill and Backing Plate

Steps 1: 

Use a microfiber towel to remove dirt surrounding the headlight after spraying some water on it.

Steps 2: 

Remove the top layer of foggy or yellow plastic from the lens. You need some compound, metal polish, car polish, and sandpaper in different sizes. All of these items contain have aluminum oxide.

  • In order to prevent damaging the paint on the surrounding body panels while sanding, you mask up the surrounding panels with some masking tape.
  • Spray some water on the lens and start rubbing with 600 grit sandpaper. For best result, rub first horizontally, keep rubbing with light to medium pressure and spray water as you need. Now you can see the foggy or yellow in plastic is gone but now there’s an identical white haze on the lens these are rubbing scratches.
  • Now at the 1500 grit and start rubbing again, this time instead of going vertical, so you can remove the horizontal scratches. now you can see a little bit of haze.
  • To remove the horizontal haze, use 3000 grit sandpaper and rub well horizontally and vertically to remove all the scratches.

Steps 3: 

In this step, you need a microfiber towel to use compound but you can use a hand, wool pad or you can use drill then you need a headlight polishing kit (drill is much quicker). Remove the masking tape and get some compound on the pad and start buffing, keep maintaining a consistent Spade with a uniform pressure with horizontal overlapping passes and then switch to vertical passes, get some polish to bring back the factory shine. now the clarity is back just like in a brand new headlight.

Steps 4:

  • Using UV hard-code or UV heat lamp
  • Headlight coating
  • Clear coat
  • Headlight Covers

Steps 5: My Recommended Option is!

  • Headlight Protecting Films: The best thing is this doesn’t get folded under the lens, like coating and yellowing, so when this goes bad remove it and install a new one. This is the only way to restore headlights permanently.
