Over time, your vehicle's headlights can become cloudy, yellowed, or hazy due to oxidation, UV exposure, and road debris. Not only does this make your car look older, but it also reduces nighttime visibility, which can be a serious safety issue. While professional restoration or replacement is always an option, many car owners successfully restore their headlights using a few simple DIY methods.
Why Do Headlights Get Cloudy?
Most modern headlights are made from polycarbonate plastic, which is durable but susceptible to oxidation. Over time, exposure to sunlight and the elements causes the clear outer layer to degrade, leading to that dull, foggy appearance.
DIY Methods to Restore Headlights
Here are some of the most effective at-home solutions to restore clarity to your headlights:
Method 1: Toothpaste and Baking Soda
Toothpaste contains mild abrasives that help remove oxidation, and baking soda enhances the cleaning power.
What You’ll Need:
Non-gel white toothpaste (with baking soda if possible)
Baking soda (optional)
Microfiber cloth or soft rag
Water and a spray bottle
Masking tape (to protect surrounding paint)
Steps:
Clean the headlights with soap and water, then dry them completely.
Apply masking tape around the headlights to prevent accidental scratches on the paint.
Apply a generous amount of toothpaste (or a paste made from baking soda and water) to the headlight.
Use a microfiber cloth to rub the toothpaste in circular motions for about 5 minutes.
Spray water on the headlight and wipe away the paste with a clean cloth.
Repeat if necessary, then apply a UV sealant or car wax to protect against future oxidation.
Method 2: Sandpaper and Clear Coat
For headlights with heavier oxidation, wet sanding can be more effective.
What You’ll Need:
Sandpaper (800, 1,500, and 2,000 grit)
Spray bottle with water
Microfiber cloths
Rubbing compound
UV-resistant clear coat
Steps:
Wash and dry the headlights thoroughly.
Tape off the surrounding area to prevent damage.
Spray water on the headlight and start sanding with 800-grit sandpaper in horizontal strokes.
Move to 1,500-grit, sanding in the opposite direction (vertical strokes).
Finish with 2,000-grit in circular motions for a smooth surface.
Wipe the headlights clean and apply a rubbing compound with a microfiber cloth.
Once dry, apply a UV-resistant clear coat to prevent future oxidation.
Method 3: DIY Headlight Restoration Kits
If you want a simpler approach, headlight restoration kits from auto parts stores come with everything you need, including polishing compounds and UV sealants. These kits typically follow a sanding and polishing process similar to the one described above.
How to Keep Headlights Clear Longer
After restoring your headlights, protect them with these tips:
Apply a UV protectant or wax every few months.
Park in shaded areas or use a car cover.
Consider headlight protection film to prevent future oxidation.
