How To Clear Foggy Headlights

Kits That Make Your Headlights Sparkle


Fogged headlight lenses not only make your car look tired but also restrict the amount of light illuminating the road ahead of you. Headlight restoration kits are cheap and can produce dramatic results.

Money Saved: About $40

Time Required: 30 minutes to 1 hour

Tools Required:

  • Latex glove
  • Electrician's tape
  • Buffing wheel (optional)
  • Sponge

Materials Required:

  • Headlight restoring kit
  • Newspapers
  • Water

Expenses

In the photo above are two different headlight restoring kits, the Turtle Wax Headlight Lens Restorer (typically sold for about $10) and Sylvania's Headlight Restoration Kit, selling for about $20. There are many other kits available at different prices, including some that include a buffing wheel to eliminate the manual labor.

Expenses

Most headlight restoration kits include an abrasive compound and sandpaper (in grades of varying roughness) to remove the outer layer of yellowed, oxidized plastic and clear the lens. Some include a buffing wheel that can be attached to a power drill. One YouTube video even shows headlights being cleaned with toothpaste (which is slightly abrasive) and a clean cloth towel.

One difference between the two kits — and probably the reason for the price difference — is that the Sylvania kit includes a glove, tape and a liquid "UV Block Clear Coat" to protect the lens from refogging once it has been cleaned. I have one gripe with the Sylvania kit, because the clarifying compound comes in a little packet that can't easily be stored. This means this kit will probably be a one-shot deal. The Turtle Wax kit doesn't have the extra goodies, but the pads can be reused and the bottles contain a larger amount of the clarifying compounds.

Expenses

To be clear (so to speak), what we're actually tackling in this project is the plastic lens covering the headlight bulbs, as shown on this 2001 Acura TL. This plastic lens protects the headlight from dirt and debris blown around on the road. Over time, these lenses become scratched, pitted and clouded by exposure to the sun. Replacing the lenses is expensive, so many car owners opt just to clean them.

The following steps are an overview of the ones I took with these two kits. Whichever kit you use, make sure you follow the included directions carefully. Use the products in the correct order and keep in mind that the headlights won't look clear until you are finished and the residue is washed off.

Expenses

I use the electrician's black tape from the Sylvania kit to protect the paint around the headlights from the abrasive compound and to ensure I don't accidently scratch the paint with sandpaper. The electrician's tape is particularly good for this task because it pulls off easily when you are finished without leaving any sticky goo on your car's paint. You might also consider using extra protection and tape some newspaper onto the car to protect the finish. Once you start getting into the project and the how-to zeal takes hold, the compounds tend to fly onto painted surfaces.7

Expenses

I have used the Turtle Wax kit on the left headlight and the Sylvania on the right. I applied the Turtle Wax products in two stages, rubbing on the lens-clarifying compound first to see if that did the job.

Expenses

If the clarifying compound doesn't get results, you spray on the lubricant and use the abrasive pads. I use both chemicals for this test.

Expenses

With about 10 minutes of work, here's what the left headlight looked like. Not bad.

Expenses

The Sylvania kit called for washing the headlight lens with a surface activator. Then I applied the clarifying compound from the packet to the different levels of sandpaper for sanding and polishing the lens. Finally, I applied the UV Block Clear Coat.

Expenses

Here's what the headlights look like after applying the products from the different kits and sanding each one for about 15 minutes.

Expenses

I then tried the Sylvania kit on another car with more seriously fogged headlights.

Expenses

I spent more time reading the directions this time and the results were better.

Clearing your headlights is easy, inexpensive and the results are satisfying. Once you do it and see how it sharpens up the look of your car, you'll find yourself recommending it to all your friends with older cars. Even better, there might be a little more from your headlights when you're driving at night.

    Call me cheap but I didn't want to spend $15 on a kit for what I figured would be a 1 shot deal plus not knowing if it would be effective. I used some Turtlewax polishing compound ( scratch remover ) I've had on hand for years & it did the trick very quickly.

    Forget the kits, forget the sandpaper (Really?), forget all that time... Go to the store and buy a can of silicone spray lubricant, spray a rag very thoroughly, I mean soak it, and then wipe headlight lens in circular NON STOP motions to remove the grunge in about 30 seconds. Leaves you with nice clear lenses, and cost nothing in time and money. WORKS LIKE A DREAM!!!!!!

    What about a deoxidizer? saw something on facebook about that?

  • The car used in the before and after here - aren't even the same cars. Very dishonest post here. Look CLOSELY at the center grill of the before pic - it's SILVER - but it isn't in the "after" pic. Heck look at the license plate - it ends with a 4 but the "after" pic has a piece of the license plate displaying and whatever the number is - it ISN'T a 4 - take a close look again at the pics - this entire post is a lie.

    No matter what you do nothing lasts real long and eventually you'll have to do it again. That being said the cheapest thing to use is shampoo. Laugh if you want but give it a try and you'll be surprised at the results.

    I've used gel toothpaste with okay results. Not long lasting but okay.
