To clean headlight haze, mix baking soda with water, apply the paste, scrub, and rinse thoroughly. Clear headlights improve visibility and enhance the overall appearance of your vehicle.
Over time, headlights can develop a cloudy, yellowish haze due to exposure to UV rays, dirt, and other environmental factors. This buildup can reduce the effectiveness of your headlights and compromise road safety. Luckily, restoring clarity to your headlights is a simple process that can be done at home with basic supplies.
By following the steps outlined below, you can easily clean headlight haze and ensure optimal performance from your vehicle’s headlights.

Why Do Headlights Become Hazy?
Headlight haze is primarily caused by the oxidation of the polycarbonate plastic that is commonly used in modern headlight covers. Unlike the older glass covers, polycarbonate is prone to degradation due to prolonged exposure to the sun’s ultraviolet (UV) rays. Over time, the outer layer of the plastic becomes cloudy and yellowed, which results in the foggy appearance of headlights.
Other contributing factors to headlight haze include:
- Road grime and debris: Dirt, dust, and small particles kicked up from the road can scratch the surface of your headlights, dulling their shine.
- Harsh weather conditions: Exposure to rain, snow, and fluctuating temperatures can exacerbate the cloudiness of headlights.
- Chemicals: Car wax, cleaning agents, or environmental pollutants can stick to the headlight lens, contributing to the hazing effect.
How to Clean Headlight Haze
There are several effective methods to clean headlight haze. Below are the most commonly used approaches, ranging from simple DIY solutions to specialized restoration kits.
Method 1: DIY Toothpaste Cleaning
Toothpaste contains mild abrasives that can help remove the oxidation layer on your headlights, making it a quick and inexpensive fix.
Materials Needed:
- Regular toothpaste (whitening variants work best)
- Soft cloth or microfiber towel
- Water
- Masking tape (optional)
Steps:
- Prepare the area: If you want to avoid getting toothpaste on your car’s paint, tape around the headlight to protect the surrounding areas.
- Apply toothpaste: Squeeze a small amount of toothpaste onto a clean cloth.
- Rub the headlights: Gently rub the toothpaste in a circular motion across the headlight lens. The abrasiveness of the toothpaste will help to clear away the haze. Continue rubbing for 2-3 minutes.
- Rinse with water: Use clean water to rinse the headlight thoroughly, removing all toothpaste residue.
- Buff the surface: Use a microfiber cloth to dry and buff the headlight to a clear finish.
Results: This method can improve the clarity of headlights significantly, but it’s generally a short-term solution. The haze may return after a few weeks or months.
Method 2: Baking Soda and Vinegar Solution
Baking soda, with its gentle abrasive properties, can also help remove headlight oxidation, while vinegar acts as a mild cleaning agent.
Materials Needed:
- 2 tablespoons of baking soda
- 1 tablespoon of vinegar
- Soft cloth
- Water
- Masking tape (optional)
Steps:
- Mix the solution: Combine baking soda and vinegar in a small container, mixing until a paste forms.
- Apply the paste: Spread the paste on the headlight, using a clean cloth or sponge.
- Scrub the headlight: Scrub the surface using small circular motions to lift off the oxidation.
- Rinse with water: Thoroughly rinse off the paste with clean water.
- Dry the surface: Wipe the headlights dry with a soft cloth.
Results: Like toothpaste, this is a temporary fix, but it’s a good alternative using common household items.
Method 3: Headlight Restoration Kits
For a more professional finish, you can use a headlight restoration kit, which typically includes a polishing compound, sanding discs, and a UV protectant. These kits are designed to remove the hazy layer more thoroughly and offer longer-lasting results than DIY methods.
Materials Needed:
- Headlight restoration kit (available at most automotive stores)
- Water
- Masking tape
Steps:
- Prep the area: Clean the headlights with soap and water, and tape around the headlight to protect the paint.
- Sand the headlight: Most kits come with multiple sanding discs of varying grit. Start with the coarsest grit and sand the surface of the headlight, using a spray bottle to keep the surface wet. Sand in a horizontal direction, then move to finer grit sandpaper, sanding in a vertical direction.
- Polish the headlight: Once sanding is complete, apply the polishing compound to a cloth and rub it onto the headlight lens. Buff in circular motions until the haze is gone.
- Apply UV protectant: After polishing, apply the UV protectant provided in the kit. This is an essential step, as it prevents the headlights from quickly becoming hazy again due to UV exposure.
- Buff and dry: Use a microfiber cloth to buff the surface until clear.
Results: Restoration kits provide longer-lasting results and are highly effective at restoring even heavily hazed headlights. The UV sealant adds protection, prolonging the clarity of the lenses.
Method 4: Sandpaper and Clear Coat
For those looking for a more permanent solution, wet sanding followed by applying a clear coat can restore clarity to your headlights and protect them from future UV damage.
Materials Needed:
- Sandpaper (600, 1000, 2000, and 3000 grit)
- Spray bottle with water
- Automotive clear coat
- Masking tape
- Microfiber cloth
Steps:
- Prepare the surface: Clean the headlights and tape off the surrounding paint.
- Wet sanding: Start with the 600 grit sandpaper, spraying the headlight with water while sanding in a horizontal direction. Move to higher grit sandpapers, repeating the process, but changing the sanding direction with each progression (horizontal, then vertical).
- Apply clear coat: After sanding and cleaning, spray the headlight with an automotive clear coat to protect the lens from UV damage.
- Buff and dry: Allow the clear coat to dry completely and then buff the headlight with a microfiber cloth.
Results: This method is one of the most durable and provides professional-level results. However, it requires more time and attention to detail than the DIY methods.
Preventing Future Headlight Haze
Once you’ve restored your headlights, it’s essential to maintain them to prevent future hazing. Here are a few tips to keep your headlights clear:
- Regular Cleaning: Wash your headlights with soap and water regularly to prevent dirt and grime from building up.
- UV Protection: Apply a UV protectant specifically made for headlights after cleaning or use a restoration kit that includes UV protection.
- Parking in the Shade: When possible, park your vehicle in a garage or shaded area to reduce exposure to direct sunlight, which accelerates oxidation.
- Headlight Covers: Installing headlight covers or using protective films can help reduce the wear and tear on your lenses.
Frequently Asked Questions
Here are some FAQs about cleaning headlight haze –
1. How often should I clean my headlights?
It’s advisable to clean your headlights every few months or whenever you notice them becoming cloudy. Regular cleaning prevents debris buildup and oxidation.
2. Can I use household items like toothpaste to clean headlight haze?
Yes, toothpaste is a common DIY method for removing light haze from headlights. However, it’s a temporary fix, and the haze may return after a few weeks or months.
3. What’s the best way to prevent headlight haze from coming back?
Applying a UV protectant after cleaning is the best way to prevent headlight haze from returning. Regularly cleaning your headlights and parking in shaded areas can also help.
4. Is it safe to use sandpaper on my headlights?
