So you want to clean your car's headlights? Well, you’ve come to the right place as your headlight lenses may have gone yellowy over time, become fogged or filthy, or might have found new purpose as a terrarium for indigenous worms and insects. They're such an eyesore, and boy do they affect a car's overall look.

Luckily, The Drive’s top-notch How-To department is here to help get those lagging lights luminous once again. Driving with crappy headlight lenses isn’t just unsafe for you, tootling along in the inky blackness of night. It's also quite unsafe for others on the road. Restoring your headlights to fresh-from-the-factory clear is also one of the easiest ways to make your aging ride look like new. 

The bottom line is your lenses need a good polishing, and here's how to do it.

Safety First

Working on your car can be messy, especially when you’re cleaning surfaces you’ve never bothered to clean before—hello, bug-splattered headlight lenses—so here’s exactly what you’ll need to ensure you don’t die, get maimed, or lose a finger and that you keep your jeans, shirt, and skin spotless—hopefully.

  • Mechanic gloves to protect your hands.
  • Long-sleeve shirt to protect your arms.
  • A mask or ventilator to filter chemical fumes and odors.
  • Safety glasses

How To Clean Headlights

Let’s do this! 

Cleaning and Masking Your Headlights
  1. Wash the headlight lenses, those plastic assemblies that protect the bulbs, with soap and water. Pay particular attention to any surface imperfections, bug carcasses, and any detritus that’s embedded itself into the surface.
  2. Dry lenses thoroughly.
  3. Tape the areas around the lenses to protect your car’s paint while sanding and polishing. 
Sanding Your Headlights
  1. Using the spray bottle, dampen a sheet of 1000-grit sandpaper.
  2. Spray the entire lens with water to thoroughly dampen it.
  3. Rub the dampened sandpaper over the lens evenly, occasionally spraying the lens with additional water to keep wet (dry-sanding the lens can cause damage).
  4. Continue for 5-10 minutes.
  5. Wipe down the lens with a microfiber towel and re-spray with water. 
  6. Dampen a sheet of 2000-grit sandpaper and repeat the sanding process, occasionally spraying the lens with water. 
  7. Continue for five minutes.
  8. Wipe down the lens with a microfiber towel.
  9. Repeat the wetting-and-sanding process with 3000-grit sandpaper. 
  10. Continue for five minutes.
  11. Clean and dry the lens completely.
  12. Repeat the entire process with the second headlight lens.
Polishing and Waxing
  1. Squeeze a little polish onto a clean microfiber towel or buffer pad.
  2. In a circular motion, rub the polish into the lens, as directed. 
  3. You’ll know when you’re done when the lens is clear.
  4. Wax the lens in the same way you’d wax the rest of the car.

You’re done!

Expert Advice 

The Drive asked RJ de Vera, Global Customer Engagement Leader at Meguiar's, for tips on the best methods and products to use while cleaning your car's headlights. 

  • If you have headlights with light oxidation or yellowing and you want to work by hand, a basic kit is all you'll need. Can I suggest Meguiar’s® Basic Headlight Restoration Kit? With this kit, it’s recommended to mask off around the headlights and soak the included pads in water for a minute. Then, you lightly sand with each of the four different pads working from coarser to finer. This is repeated multiple times on each headlight until they are clear again.
  • If your headlights have heavy oxidation, and you have a corded drill (YAY, POWER), can I have you consider Meguiar’s® Heavy Duty Headlight Restoration Kit? With this kit, you clean the lights thoroughly and then mask off around each light. Lightly sand with the two different grades of fine sandpaper and water. Work the first disc horizontally and the second vertically, making sure they have a uniform frosted appearance before following with the included cleaner and polish. Here you apply the polish to the included wool buff pad using a standard corded drill to polish the plastic back up to clarity. Work for 1-2 minutes wiping off the residue before it dries, then repeat this process if needed until the lenses look like new again. Clean with a good glass cleaner and apply a medium coat of the included headlight coating overlapping your passes by 50 percent. Allow to cure and apply a second coat for a thorough seal. You're all done.
