What You'll Learn
Use a restoration kit
If you're looking for a straightforward way to clean your car's foggy headlights, consider using a headlight restoration kit. These kits are designed specifically for cleaning headlight lenses that have become fogged up due to UV exposure. You can find them at most auto supply stores. Here's a step-by-step guide on how to use a restoration kit to clean your plastic headlight covers:
Prepare the Headlights
Before applying any cleaner, ensure the headlights are free of dirt, bugs, and grime. Start by spritzing the headlights with a mild cleanser or plain water, and gently wipe them down with a soft cloth or sponge. Make sure to remove all contaminants from the surface. This step is crucial as it ensures that you're working with a clean surface and prevents scratching the paint job.
Apply the Cleanser
Now, it's time to apply the product from your restoration kit. You can also use toothpaste or baking soda for this step. Distribute a generous amount of the cleanser fairly thickly over the headlight lenses. If you're using baking soda, mix it with a small amount of water first to create a thick paste. Allow the cleanser to sit for a few minutes, giving it time to work on the foggy surface.
Work the Cleanser
Using a soft-bristle brush or a clean rag, gently work the cleanser into the headlight lens using circular motions. Be careful not to apply too much pressure, as the cleanser is abrasive and can gouge into the plastic surface. You should start seeing the yellowness or fogginess disappear as you work.
Buff and Polish
Once you've covered the entire surface, use a clean rag or towel to buff away any residual cleanser. Pay extra attention to any stubborn, dried-on bits. Spritz these areas with clean water and then polish them until dry.
Maintain Regularly
To prevent the headlights from becoming foggy again, regular maintenance is key. Wash the headlights often with a mild detergent and a soft-bristle brush or sponge, and always dry them thoroughly afterward. You can also use products like Honda Spray Cleaner and Polish, which has a UV protectant and makes bug splatter easier to wipe off.
By following these steps and using a headlight restoration kit, you can effectively clean and restore your plastic headlight covers, improving visibility and enhancing the aesthetic appeal of your vehicle.

Clean with toothpaste
Cleaning your car's plastic headlights with toothpaste is a straightforward process. It is a good option if you need to clean foggy headlights immediately, although it is not a permanent fix. Toothpaste polishes your car's headlights back to their original shine, but the effects will only last a few months.
To clean your headlights with toothpaste, start by taping off the area around your headlights with automotive masking tape or painter's tape. This will protect your car's paint from the toothpaste, which can be abrasive.
Next, spritz your headlights with a mild cleanser and gently wipe away any dirt, debris, or gunk that has accumulated on the surface. After cleansing, wipe down the surface with a dry towel or rag until it is completely dry.
Now, apply a generous amount of toothpaste to your headlights. You can apply the toothpaste while the headlights are still wet to produce a bubbly lather similar to soap. Using circular motions, gently work your way around the surface of the headlight with a brush or cloth. You should see the yellowness or fogginess start to disappear.
If your headlights are still a little yellow and foggy after rinsing off the toothpaste, simply repeat the cleaning process 1 to 2 more times. Once you are happy with the results, dry your headlights with a microfiber towel and apply a coat of car wax. This will protect your headlights from dirt, scratches, and UV rays, helping to keep them from yellowing as quickly.
Finally, apply a UV-resistant sealant to shield your headlights from the sun. This will help protect your headlights from oxidizing UV rays and keep them shining brightly.

Polish with baking soda
If you are looking for a way to clean your plastic headlight covers, there are several methods you can try. One common method is to use a headlight restoration kit or a headlight lens restoration product, which can be found at most auto supply stores. These kits are designed specifically for cleaning headlight lenses that have become foggy due to UV exposure.
However, if you are looking for a more DIY approach, you can try using baking soda. Here is a step-by-step guide on how to polish your plastic headlight covers with baking soda:
First, ensure that you are working with a clean surface. Spritz your headlights with a mild cleanser and gently wipe away any dirt, debris, or gunk that may have accumulated on the surface. You can use a brush to gently work your way around the surface of the headlight in circular motions. Be careful not to use too much force, as the cleanser is abrasive and you don't want to scratch the plastic.
Next, wipe down the surface with a dry towel or rag until it is completely dry. Then, take your baking soda and distribute it fairly thickly over the headlight lens. You can do this by sprinkling the baking soda directly onto the lens or by mixing it with a small amount of water to form a paste.
Using a clean, soft cloth, gently buff the baking soda into the lens in circular motions. The baking soda will act as a mild abrasive, helping to remove the yellowing or fogging that has built up on the lens. Continue buffing until you see an improvement in the clarity of the lens.
Finally, use a clean, damp cloth to remove any residual baking soda and polish the lens until it is dry. You should immediately notice increased visibility and brighter, clearer headlights!
This method is a cost-effective and straightforward way to improve the appearance and effectiveness of your headlights. However, it is important to note that this is a temporary solution, as the UV coating on the headlights will eventually break down again due to exposure to sunlight. To maintain clear headlights, you may need to repeat this process every few months or consider investing in a headlight restoration kit or protective sealant.

Sand and use micromesh
Sanding and using micromesh is a popular method for cleaning plastic headlight covers. This method involves gently sanding the headlight cover with escalating grits of micromesh and then polishing it.
To begin the process, it is recommended to soak the sheets of sandpaper in water before starting with the grit that suits your situation. When sanding, always sand in one direction. The higher the number of the sandpaper grit, the finer it is. For example, if the headlight is just dull or yellowed, start with 1500 grit and work your way up to 2500 grit.
When wet sanding, a cross-hatching technique is recommended to help remove scratches. Make diagonal passes and alternate directions, starting with the heaviest-grade sandpaper. As you progress to finer-grade sandpaper, the headlight lens should gain more clarity. Using circular motions can also be effective in gaining clarity, but it is difficult to achieve without a machine polisher.
After the sanding process, the lens may still be hazy, but it should feel smooth. At this point, you can use a dual-action polisher with a paste or liquid compound to further improve clarity. A wool pad will provide more cut than a foam pad, but be careful not to generate too much heat.
Wet sanding is a messy and time-consuming process, requiring approximately 30 to 45 minutes per headlight. However, it is an effective method for restoring severely damaged headlight lenses and can be a cheaper alternative to professional cleaning services.

Protect from UV damage
To protect your car's plastic headlight covers from UV damage, there are a few options you can consider:
Park in the Shade or Use a Garage
If possible, park your car in a shaded area or in a garage to minimize direct exposure to sunlight and UV rays. This simple solution can significantly reduce the UV damage to your headlights over time.
Headlight Protection Film
Applying a headlight protection film, also known as Paint Protection Film (PPF), is a popular and effective method to protect against UV damage. PPF is composed of polymers that are resistant to UV light, as well as other forms of damage such as scratches and pitting. It can be applied to any new or used vehicle, and it creates a hydrophobic surface while improving clarity. This is a more advanced and permanent solution compared to regular waxing.
UV-Resistant Coatings and Sealants
You can also apply UV-resistant coatings or sealants specifically designed for headlights. These products can be sprayed or coated onto the headlights, providing an extra layer of protection against UV rays. Some options include Meguiar's Keep Clear Headlight Coating, which promises UV protection for an entire year, or UV-resistant 2K clears.
Headlight Covers
If you're looking for a temporary solution while your car is parked for extended periods, you can use headlight covers or even drape any material over the headlights that can block UV rays. This could be a car cover that protects the entire vehicle, or you could specifically cover the headlights with aluminum foil when the car is not in use.
Regular Cleaning and Maintenance
Finally, regular cleaning and maintenance of your headlights can help extend their lifespan and minimize UV damage. Keep your headlights clean by removing any built-up residue and protecting them with polish and ceramic coatings.
