Best DIY Way to Clean Headlights

Clean your headlights with dish soap and water, then air-dry and apply masking tape along the edges of each light. Add a dab of gritty toothpaste to a damp microfiber cloth or toothbrush, using pressure to scrub the headlights in circular motions. Rinse and dry the lenses, then apply car wax with a microfiber cloth.

Cleaning Headlights with Toothpaste

  1. Use a microfiber cloth dipped in warm, soapy water to clean any dirt or surface residue from your headlights. [1]
    • Try to avoid getting the soapy water on your car’s paint—the dish soap may strip off the protective wax. [2]
    • Toothpaste is one of the most effective household methods for cleaning headlights. However, it might not be as effective or long-lasting as using a headlight restorer or restoration kit.
  2. Use masking tape or painter’s tape to cover the painted finish around each headlight. This can help prevent the toothpaste from scuffing or scraping the paint from your car as you’re polishing your headlights. [3]

  3. For best results, choose a gritty toothpaste (not a gel) with baking soda—these abrasive ingredients can remove oxidation. [4] Add about 1 teaspoon (1 g) of toothpaste to a damp microfiber cloth or soft toothbrush and wipe the headlights in a circular motion. [5]
    • While toothpaste is generally safe for headlights, test it on a small area before covering the entire lens to make sure it won’t cause any unusual reactions. [6]
    • If you don’t have a gritty toothpaste, mix it with about 1 teaspoon (6 g) of baking soda before applying it to your headlights.
    • Use pressure as you work the toothpaste into the headlight lens. Apply more toothpaste as needed to remove the yellowing from each headlight. [7]
  4. Dip another clean microfiber cloth in warm water and wipe the toothpaste off of each headlight. [8] Dry with another microfiber cloth or allow the headlights to air-dry, then apply the wax as directed. Car wax can help prevent future yellowing or damage from UV rays. [9]
    • Most waxes require you to apply it to a microfiber cloth, then create a thin layer on the surface of the car by working in a circular motion. [10]
      • Let the wax dry, then buff it off with a dry microfiber cloth or car buffer.

Cleaning Headlights with Vinegar and Baking Soda

  1. Dip a microfiber cloth in warm water and dish soap. Wash away all the dirt and grime from each headlight. [11]
  2. Protect the painted surface of your car from the abrasive baking soda and vinegar by sticking tape in a border around each headlight. [12]
  3. Baking soda and vinegar are both pantry staples that are environmentally friendly and can be effective for cleaning headlights . In a small bowl or bucket combine 2 parts of distilled white vinegar with 1 part baking soda. Mix until well combined. [13]
    • For example, combine 2 cups (0.47 L) of vinegar with 1 cup (272 g) of baking soda.
  4. Rub each headlight vigorously in circular motions to remove as much of the cloudy yellowed residue as possible. [14]
    • To get the most out of the baking soda vinegar solution, try to scrub while the mixture is still fizzing. [15]
    • You may have to rewet the cloth several times with the baking soda vinegar solution as you scrub.
  5. Rinse and refill your small bucket or bowl with warm water. Dip a clean microfiber cloth in the water and wipe away all the baking soda and vinegar residue from the headlights. [16]

Cleaning Headlights with a Headlight Restorer

  1. Use a microfiber cloth dipped in warm water and dish soap to clear away any dirt or grime off each headlight lens. Dry the area with a clean microfiber towel, then use painter’s tape or masking tape to outline each light.
    • Alternatively, spray the area with glass cleaner and clean with a microfiber cloth.
  2. To clean your headlights , auto detailing expert Chad Zani recommends applying Chemical Guys headlight restorer to a microfiber cloth or a “ cordless drill and a microfiber pad .” This headlight restorer typically costs around $20.
    • The micro-abrasives in this product can peel back the layers of clouded plastic and the wax sealant creates a clear coat that blocks harmful UV rays. [17]
    • Alternatively, apply a regular car polish compound to your headlights using a microfiber cloth.
  3. Wipe off the residue with a clean microfiber towel and inspect the area for any yellowing you may have missed. Repeat this process on both headlights until they’re both clear and shiny. [18]

Cleaning Headlights with a Restoration Kit

PDF download Download Article
  1. Dip a microfiber cloth in a solution of warm water and a drop or two of dish soap. Gently scrub the surface of the lens to remove any dirt or grime from the surface.
    • For best results, choose a dry day when the weather is warm and move your car so the headlights are not in direct sunlight. [19]
    • Make sure not to get the dish soap-saturated water on the car’s paint. If you’d like a safer alternative to dish soap that you can use on paint, try regular car wash soap .
  2. Masking tape or painter's tape can help you avoid scratching up the paint while you’re sanding down the headlight lenses. [20]
    • Optionally, wipe down the headlights using a clean microfiber cloth and a bit of rubbing alcohol to make sure they’re extra clean.
  3. Most restoration kits come with a surface activator that breaks down the original UV coating and removes any oils. [21] Most kits direct you to leave the surface activator to sit for at least 30 seconds and then rinse it off with water. [22]
    • Check your kit’s instructions to see how long to leave the activator on before washing it off.
    • Most headlight restoration kits cost between $10 to $25. [23]
  4. Dip or spray the lowest-grit sandpaper with water. Sand the surface of the headlight in a circular motion until it’s smooth across the whole lens. Rinse with water and repeat with the next highest-grit sandpaper. Rinse with water again and use a clean microfiber cloth to dry the area. [24]
    • Optionally, sand in one direction with the lowest-grit paper. Rinse the area with water and use the next-highest-grit paper to sand in the opposite direction. [25]
    • The higher the number on the sandpaper, the finer the grit. Slowly increasing the grit removes the old coating and leaves the lenses with a smooth finish. [26]
  5. Apply half of the included buffing or clarifying compound to a clean microfiber cloth and buff it onto one of the headlight lenses. Work the compound into the lens in a circular motion for about 5 minutes, then rinse with water and dry with a microfiber towel. Repeat this step for the second headlight. [27]
    • If your kit doesn’t come with a clarifying compound, buy a car polishing compound and apply it as directed.
    • Depending on the amount of compound in your kit, you may want to use up to 3 coats of buffing compound until your headlights look completely clear and shiny.
  6. Use a clean microfiber cloth to apply a thick, even layer of UV coating to the headlight. Work in circular motions, making sure to cover the entire surface. Repeat for the second lens. Allow the coating to fully cure for 4 to 6 hours before driving. [28]
    • Make sure your car is parked in an area where it can’t be exposed to water or high humidity that can disrupt the curing process.
    • This method is the most effective (but the most expensive) for cleaning your headlights. Most restoration kits last for about 5 years before your headlights need another treatment. [29]
    • After the coating has completely cured, remove the masking or painter’s tape and you’re all good to go!

Keeping Your Headlights Clean

  1. Auto detailing expert Chad Zani says that “the reason [that a] headlight looks yellow is that the plastic has been broken down” by the sun’s UV rays. To prevent future yellowing or UV damage, try to park your car in a garage or in shade. You can also place a car cover over your vehicle to protect it.
  2. Cleaning your headlights with a household glass cleaner after every drive can help keep them clear, clean, and bright. [30]
    • If you notice that your car’s headlights are getting yellow, foggy, or hazy, then it’s time to use one of the methods above to restore their shine. [31]
    • If your lenses are clear but the lights inside seem dimmer than they used to be, it may be time to get new bulbs.
  3. If the hard coat on your headlights starts to flake or peel off or if you see cracks deep into the lens, have your headlights looked at by a professional. They may be able to repair any peeling or replace the assembly if it’s cracked.
    • A new headlight assembly can cost between $350 to $2,000 depending on the make, model, and year of your car.
  4. Most headlights are plastic and can be cleaned with the methods listed above. Glass headlights on older models are more complicated and are best examined by professional body technicians. If your glass headlights are wearing out, take them in and have them checked.

    Household remedies can help temporarily, but they won't fix the problem. For instance, if you rub petroleum jelly on your headlights, they will look better for as long as the petroleum jelly hangs around. Similarly, any kind of oil-based product, like olive oil, will make a dull headlamp look better, but only momentarily.

      About This Article

      Article Summary X

      If your headlights are looking hazy or fogged over, you can clean them using a few simple supplies to get them looking new again. First, wash your headlights with soapy water and let them dry. Then, apply painter’s tape around the perimeter of each headlight so you don’t accidentally damage the surrounding paint. For a quick fix, apply toothpaste to a damp cloth and buff the toothpaste into each headlight for about 5 minutes. Toothpaste is mildly abrasive, and it can help remove any buildup on your headlights. Rinse off each headlight with water and let them air dry. You can also try using baking soda and vinegar. Mix 2 parts white vinegar with 1 part baking soda, and rub the mixture into each headlight with a cloth for a few minutes. Rinse your headlights with water and repeat if needed. For really hazy headlights, try wet sanding them. First, wet the headlights and some 1000-grit sandpaper with water. Then, sand each headlight using horizontal strokes for 5 to 10 minutes, keeping the sandpaper wet at all times. Repeat with 2000-grit and then 3000-grit sandpaper, changing the direction you sand in each time. Finally, polish and wax your headlights to really make them shine. If you want to learn how to protect your headlights with plastic adhesion, keep reading the article!
