How to effectively remove oxidation from headlights

Keeping your car's headlights clean is important to make sure you can see well while driving and to keep your car looking good. Over time, headlights can get dim or look cloudy, which makes them not work as well. It doesn't just make your car look less nice, but it can also be unsafe for you and other drivers.

Car headlights can turn yellow or foggy over time due to various reasons. Let's address and fix that issue. Here's why it happens and how to clear up the fog. First, the covering of headlights is often made from a plastic material, like polycarbonate.

If this material isn't sealed properly, debris from driving through dust, rocks, pebbles, and dirt can scratch up the headlights, leading to tiny chips and cracks. These small gaps let dirt accumulate, causing the headlights to turn yellow over time. This not only damages the protective sealant but also hinders the headlights from shining brightly.

Why Do Headlights Become Foggy?

When you first get a new car, everything, including the headlights, looks shiny and new. However, after a few months, you might notice a change as the gleaming headlights become foggy. This transformation is often attributed to several factors:

Many modern cars have headlights made of polycarbonate plastic. Unlike glass, this material can develop microscopic cracks when exposed to sunlight, leading to a yellowing effect that eventually gives headlights a cloudy or foggy appearance.
While polycarbonate headlights usually come with a protective coating, prolonged exposure to harsh weather conditions can cause this coating to peel off. This, in turn, makes the headlights susceptible to the elements and contributes to their foggy look.
Condensation that gets trapped in your car's lightbox is another common reason for headlights losing their clarity. The water vapor inside can create a foggy effect over time.
Regular road use can result in the accumulation of a thin layer of dirt and chemicals on your car's headlights. This layer can contribute to the development of yellowing or fogging.
Overlooking regular cleaning and maintenance of your headlights can also contribute to their foggy appearance. Dirt and grime build-up over time, diminishing the effectiveness of the protective coating.

Preventing and Fixing Foggy Headlights

To maintain clear and bright headlights, it's essential to address these issues. Regular cleaning, using appropriate cleaning agents, and applying protective coatings can help prevent oxidation and the accumulation of dirt and chemicals. Additionally, storing your car in a covered area when possible and addressing any water leaks can minimize water vapor related fogging.

Using Toothpaste

Toothpaste proves to be a cost effective solution for restoring headlights due to its formula containing small amounts of abrasive substances. It helps in cutting through stubborn grime, road particulates, and the effects of oxidation, leaving your headlights clearer and brighter.

Here's a step-by-step guide for using toothpaste for headlight restoration:

Begin by preparing for the headlight cleaning process. Protect your car's paint job by taping around the edges of the headlights. If you prefer to use less tape, you can also use plastic sheets taped around the headlights, as the adhesive on the tape can potentially damage the car paint if left on for an extended period.
Use a sensitive cloth or sponge, to apply on a small amount of toothpaste. Make sure the toothpaste does not contain any abrasive additives like silica, as these can cause scratches.
Scrub the headlight surface with the toothpaste, using circular motions. Rinse the cloth or sponge regularly to remove dirt and reapply toothpaste as needed. Continue this process until you notice the grit coming off, and your headlights start to clear up.
After thorough scrubbing, rinse the headlights with water to remove any remaining toothpaste residue. Assess the clarity of the headlights to ensure that they have cleared up to your satisfaction.
For an extra shine, you can follow up the toothpaste treatment with a headlight polishing kit. It will further enhance the clarity and longevity of the restoration.

Using Vinegar and Baking Soda

Vinegar, combined with baking soda, creates a potent cleaning solution capable of effectively removing stubborn headlight oxidation and dirt buildup. Follow these steps for a simple and powerful headlight restoration:

Start by preparing for the headlight cleaning process. To protect your car's paint, tape protective sheeting around the edges of the headlights.
In a small bucket, mix equal parts of baking soda and vinegar. As you combine them, you'll notice an instant chemical reaction. It enhances the cleaning power of the solution.
Scoop some of the vinegar and baking soda mixture onto a soft cloth or sponge. Ensure the mixture is well distributed on the cleaning tool.
Gently wipe the headlights with the vinegar and baking soda soaked cloth or sponge. The chemical reaction helps break down oxidation and dirt, making it easier to remove. If needed, reapply the mixture to stubborn areas and continue wiping.
After wiping, rinse the headlights carefully with water to remove any residue from the cleaning solution. Assess the clarity of the headlights to ensure that the oxidation and dirt buildup have been effectively removed.
For an extra shine and protective layer, you can follow up the vinegar and baking soda treatment with a headlight polishing kit. It enhances the overall appearance and longevity of the restoration.
Consider applying a UV-resistant sealant or coating after cleaning to protect the headlights from future oxidation and environmental damage.

Applying Headlight Restorer

Take your chosen cleanser, whether it's the product from your headlight restoration kit, toothpaste, or a baking soda paste. Distribute a generous amount evenly over your headlight lenses. If you're using baking soda, make sure to mix it with a small amount of water first to create a thick paste. Allow the cleanser to sit on the lens for a few minutes, letting it dry slightly.
After allowing the cleanser to set for a bit, take a soft brush and gently work in circular motions around the surface of the headlight. As you brush, you should notice the yellowing or fogging gradually disappearing from the lens.
Once you've completed the brushing process, wipe off any remaining cleanser residue from the headlight. Use a clean, damp cloth to ensure that no abrasive particles are left behind.
Take a step back and assess the clarity of the headlight lens. You should observe a significant improvement, with the yellowish or foggy appearance reduced or eliminated.
For an extra level of clarity and shine, you can follow up the cleansing process with a headlight polishing kit. It can further enhance the overall restoration results and provide a protective layer.

Keeping your car's headlights clean is really important. It helps your car look well and makes sure you can see well when driving.
