What causes headlights to be foggy?
So why do automotive headlights turn yellow and foggy? The polycarbonate lens of modern automotive headlights is exposed to the air which causes ‘cloudiness.’ It is called ‘oxidation‘. Lenses develop microscopic cracks when exposed to UV radiation. When water gets into these tiny cracks, it can cause the headlight to appear yellow and foggy.
There are several points that you should consider when checking whether your headlights became foggy or not. Inspect the lens for any cracks, and if you can see small ones, it means that moisture got inside and started the process of ‘clouding.’ But what are some other causes of this?
Apart from the polycarbonate material, there are other contributing factors that can make your headlight lenses appear foggy. One is using low-quality detergent or cleaners when you wash your car. These chemicals can be abrasive and actually end up causing fading and discoloration of the plastic.
Another possible cause is using too much pressure when you clean the headlights. This can also put tiny scratches on the lens which will allow moisture to enter more easily. Also, the problem may be in the rubber seals that are around the headlight lens. If these are not in good condition, they may allow moisture to enter the lens and cause it to fog up.
If your headlights are already foggy, there are a few things that you can do to try and clear them up. Here we will tell you how to do it in several methods.
How can I make my foggy headlights clear again?
If the headlights are only slightly foggy, you can try and restore them using an abrasive, like toothpaste, and lots of scrubbing. First, clean the headlights with Windex or soap and water. Then, using a soft cloth, rub a fingertip amount of toothpaste onto the wet headlight. (Toothpaste with baking soda works best.) Rub in a circular motion for two to three minutes. Rinse with water and dry.
If this doesn’t work, or if your headlights are really cloudy, you can try using a headlight restoration kit. These kits come with different grades of sandpaper and polishing compounds. You start by wet-sanding the headlight lens with the coarsest sandpaper until the haze is gone and then progress to finer and finer grits until the lens is clear. Finally, you polish the lens to restore shine.
You can also buy a headlight restoration product that comes in a spray bottle. You just spray it on and wipe it off. Some of these products actually contain abrasives, so be sure to read the label before you buy. If your headlights are severely oxidized, you may need to replace them. This is a job that is best left to a professional.
You should also be sure to protect your headlights from fogging up in the future. You can do this by regularly cleaning them with soap and water and then applying a sealant designed for plastic headlight lenses. These products form a barrier on the lens that repels water and protects against UV damage.
Will WD 40 clean foggy headlights?
Can WD-40 be used to clean foggy headlights? In case you have an upcoming car test, and you are wondering if you can quickly defog your headlights for approval, the answer is yes! It can be used as a car headlight cleaner.
To use it, firstly, wash your car headlights with soap and water to remove any grime or dirt. Then, spray WD-40 directly onto the headlight lens. Wipe it off with a clean cloth in a circular motion. Wash the headlight again with soap and water and dry it off. Your headlights should now be clear. If you do not have WD-40 at home, you can also use toothpaste to clean your foggy headlights!
WD-40 is good for your foggy headlights because it lubricates and protects the headlight lens from further damage. It also removes any residue left behind by other cleaners. Its components help to prevent future fogging.
Does WD-40 restore plastic?
It is not only useful for cleaning but also for restoring plastic. WD-40 can help to restore the color of faded plastic. It can also make plastic less brittle and more resistant to cracking.
To use it, firstly, wash the area with soap and water to remove any dirt or grime. Then, spray WD-40 directly onto the faded area. Wipe it off with a clean cloth in a circular motion. You should see the color start to fade back in!
The truth is that even if you don`t have foggy headlights, you should still WD-40 them. It will protect your headlights from future damage and keep them looking new!
How do you fix foggy plastic?
Your headlights are usually one of the first places that will show signs of wear and tear. Over time, the plastic lens can become dull, yellowed, or even foggy. If your headlights are looking worse for the wear, you’re probably wondering how to fix them.
There are a few different ways that you can clean and restore your headlights, but the best way to keep them looking like new is to regularly clean and protect them with a headlight restoration kit. If your headlights are only slightly foggy, you may be able to clean them with a headlight restoration kit. These kits come with everything you need to clean and protect your headlights, including a polishing compound, protective sealant, and instructions.
If your headlights are severely foggy or yellowed, you may try this method. Soak the plastic item in a small bucket filled with vinegar for five minutes. If the cloudiness continues, sprinkle the item liberally with a layer of baking soda and immerse it in the vinegar bath. This should dissolve the film that clings to the plastic and creates that cloud.
If the cloudiness still persists, try polishing it out with a little bit of car wax. This should buff out any remaining film and leave the plastic shining. Finally, rinse the item in clean water to remove any vinegar residue.
So, try these methods, you won`t be disappointed!
What home remedy cleans foggy headlights?
Mix the baking soda and vinegar in a small dish and then apply it in circular and side-to-side motions until your headlight is clean. You can also use baking soda and a damp cloth to clean hazy headlights. You should mix 1 tablespoon (15 mL) of baking soda with 1 cup (240 mL) of warm water. Rub the cloth over the headlight until it’s clean.
Both these home remedy methods work because such components as soda and vinegar are powerful cleaning agents. When you mix them together, it creates a chemical reaction that can help to clean your headlight. The vinegar and baking soda will also remove any grime or residue that might be on your headlight.
Will vinegar clean cloudy headlights?
Vinegar is a great tool to quickly remove dirt and discoloration from foggy or discolored headlights. You may be able to remove surface dirt and grime by washing or spraying the headlight with vinegar. If the headlights have become hazy, foggy, or yellowed, you should use a mixture made of baking soda and vinegar.
This will remove the oxidation from the surface of the headlight and make it look clear again. To clean your headlights with vinegar:
- Start by mixing one part vinegar with one part water in a bowl or container.
- Next, take a clean cloth and dip it into the vinegar solution.

Foggy headlights on any car can be a nuisance. Not only do they make it more difficult to see at night, but they can also affect your car’s resale value. Fortunately, there are a few ways to clean and de-fog your headlights.

Does white vinegar harm plastic?
The plastic and glass surfaces on most small kitchen appliances, such as blenders, coffee makers, and toasters, are safe to clean with vinegar, but you want to avoid any rubber parts or metal that vinegar can corrode. For these surfaces, use an all-purpose cleaner.
Many drivers believe that if they use vinegar on their headlights, it will damage the plastic. However, this is not true! Vinegar will actually remove the haze that builds up on the headlight, making them shine brighter.
How do you clean cloudy polycarbonate?
As we have already mentioned, polycarbonate is a tough, durable material. It is also pretty easy to clean. It is used in a variety of applications, including car headlights. Car headlights are especially susceptible to getting cloudy and dirty. This is because they are constantly exposed to the elements, including road debris, dust, and weather.
Clean polycarbonate gently using warm water with a few drops of liquid detergent and a microfibre cloth. Put plenty of water in your bucket so that you can rinse the cloth frequently. This prevents any dirt and grit from scratching the polycarbonate.
For more difficult stains, you can use vinegar or alcohol. Be sure to test these on a small, inconspicuous area first. Apply the cleaner with a soft cloth, and rub in a circular motion until the stain is gone. Rinse well with water and dry with a microfibre cloth.
