Sometimes you just notice that your headlight is looking a bit dull. You can bring back the shine by giving them a good clean! Dull headlights can be a safety hazard, not to mention they can also get you pulled over. But don't worry, there is a way to clean them and restore their shine!
Why do headlights become foggy and dim?
There are a few reasons why your headlights may become foggy and dim. One reason is because of the build-up of dirt, grease, and grime. Another reason is due to exposure to UV rays from the sun, which can cause the material to degrade and yellow over time. That is all because headlights are not made with the best materials.
The basic reason why your headlights become dim is because of the material used to make them. Polycarbonate is a type of hard plastic that is commonly used in headlight lenses. It is durable and can withstand a lot of abuse, but it is also very prone to yellowing and fading over time. This is why you often see older cars with much clearer headlights than newer ones.
Finally, some additional reasons for your headlights becoming foggy with age is because of the condensation that can form inside the headlight lens. This is especially common in cold weather climates where the temperature difference between the inside and outside of the car can cause condensation to form.
How to clean foggy headlights?
If your headlights are starting to look a bit dull, then you'll want to give them a good cleaning. To clean headlights, toothpaste and baking soda paste can be used. The fog is abrasive enough to remove without scratching or damaging the headlights, thanks to both items. Rain-X, for example, may polish away minor scratches on the car's finish. This will also help to protect the headlight from future damage.
To make the cleaning paste, mix together one tablespoon of toothpaste with two tablespoons of baking soda. Apply the paste to the headlight and use a soft cloth to rub it in. Rinse the headlight off with water and dry it with a clean cloth.
If your headlights are extremely foggy, you may need to repeat this process a few times. You can also try using a stronger cleaning solution, such as vinegar or rubbing alcohol. Be sure to test any cleaner on a small area of the headlight first to ensure that it does not damage or discolor the plastic.
Does toothpaste really clean foggy headlights?
You might be able to clear a grimy headlight with toothpaste, but in some cases, you'll need to sand it down and use a professional polishing compound. Moreover, in case your headlights are severely foggy and dim, then it is recommended that you replace them.
When toothpaste is used to clean headlights, it is important to use a non-abrasive variety. Colgate's Cavity Protection and Tom's of Maine Anticavity Fluoride Toothpaste are two examples of non-abrasive kinds of toothpaste. Abrasive toothpaste, such as those with baking soda, can damage the headlight lens. Toothpaste can help to remove minor scratches from the headlight lens. However, if the scratches are deep, then they will need to be sanded down before being polished.
What toothpaste works best to clean headlights?
You'll get the best results from Colgate with peroxide or baking soda because whitening kinds of toothpaste have more grit than non-whitening pastes. Go for paste rather than gel, as it's thicker. If you do go for a gel, look for one that has micro beads in it - these act as a scrubbing agent. Colgate is a good brand to try, as they have both a whitening paste and a gel with microbeads.
Does WD-40 clean foggy headlights?
If you have an upcoming car test and are wondering if you can quickly defog your headlights for approval, the answer is yes! It can be used as a car headlight cleaner. With WD-40, you can clean your car headlights in just a few minutes.

Once the headlight is coated, take your rag and wipe off the WD-40. You'll notice that the fogging will start to come off with it. Keep wiping until the headlight is clean. If there are any stubborn areas, you can spray more WD-40 and scrub with the rag until it's gone.
After you're finished cleaning the headlight, use a dry rag to wipe off any excess WD-40. You don't want to leave any residue on the headlight, as it can cause further fogging. Once you're done, your headlights should be clear and ready for the car test!
