Foggy or cloudy headlights are one of the most common problems found in car headlights. Hazy car headlights look unattractive and can lead to accidents as they hinder visibility while driving. Therefore, it’s essential to learn how to clean headlights with vinegar or other household cleaning agents.
A tempered form of polycarbonate plastic covers car headlights which, in spite of being remarkably stable, is naturally porous. A protective film covers the plastic, but due to extended exposure to UV rays and built-up grime, the film starts to degrade, and the polycarbonate becomes oxidized, leading to cloudiness.
While there are many commercial products you can use to take care of oxidized headlights, home remedies are often safer, cheaper, and just as effective as their more expensive counterparts. Let’s examine a few DIY solutions.
How to Clean Headlights with Vinegar
The first thing to do to clean your headlights is to wash them with dish soap, soapy water or DIY pressure washer soap and rinse to remove grime. You can also restore headlights using white vinegar.
Built-up dust and other surface grime can make driving at night difficult and very dangerous. Here are a few simple yet effective home remedies for cleaning headlights.
DIY Formula for a Headlight Cleaner
- White Vinegar
- Water
- Spray bottle
- Microfiber cloth
- Clean dusting cloth
First, wipe off the dry dust with the dusting cloth. Combine three parts water with one part white vinegar in a bowl. Pour the solution into a spray bottle and spray it onto the headlight cover.
Ensure the vinegar glass cleaner covers the headlight thoroughly and let it soak for five minutes to loosen the dirt. Wipe away the solution using a clean microfiber cloth in broad circular motions. If the yellowing on the plastic headlights doesn’t come off, remove it using a baking powder and vinegar mixture.
Cleaning Car Headlights with Vinegar Wax
Instead of going to a car wash to use a car wash soap alternative, use homemade ingredients like vinegar to make a car wax for cleaning headlights. It reduces any future fogginess from developing on the headlight cover.
Homemade Car Headlights Cleaner
- White vinegar
- 4 tablespoons of carnauba wax
- ½ cup of cider vinegar
- 1 cup linseed oil
- 2 tablespoons of beeswax
- Clean, soft cloth
- Bowl
Mix the linseed oil, carnauba wax, cider vinegar, and beeswax in a bowl and heat the wax to make a homogenous mixture. L the mixture to cool for 30 minutes. Apply it to the headlights in circular motions with a clean cloth. Leave the mixture for five minutes then wipe it with a clean, soft towel.
Headlight Cleaning with Baking Soda and Vinegar
Household cleaners are usually the easiest and best ways for cleaning oxidized headlights. One of the many uses for baking powder is headlight cleaning. Just make a simple vinegar and baking soda cleaner, either alone or in combination, to clean foggy headlights.
Try out this headlight cleaning with baking soda method. Note that this solution only provides temporary results.
Homemade Car Headlight Cleaner
- 2 parts white vinegar
- Clean cloth or paper towel
- Spray bottle
- 1 part baking soda
Mix the baking soda with the white vinegar in a measuring bowl to create foam. Dip a clean cloth into the mixture and rub it onto the headlight in small, circular motions to spread the mix. Fill a spray bottle with water and rinse off the solution with water.
Wipe the water away with a microfiber cloth or paper towel until the baking soda is completely gone. If the yellowing persists, repeat the process.
Cleaning Oxidized Headlights with Vinegar and Toothpaste
This technique is perfect for yellow plastic headlights. In our little homemade vinegar cleaner recipe, start by mixing six tablespoons of vinegar with two tablespoons of toothpaste in a bowl to form a thick paste.
With a toothbrush, apply the paste onto the car headlights. After the application, sprinkle water onto the headlights and wipe it with a clean cloth to restore headlights to their original sparkling nature.
Cleaning Foggy Headlights with Bug Spray
Apart from using toothpaste to clean oxidized headlights, bug spray is another alternative. The DEET in bug spray often removes fogginess. However, this is a temporary removal method to restore headlights as it only lasts for about a month.
The DEET in the spray functions because it melts the film on the polycarbonate plastic, and ultimately the outer layers of the plastic. It’s a quick and easy method to improve plastics’ appearance until the cloudiness returns.
Apply the bug spray onto the headlights with a clean towel. Don’t spray it directly! Rinse the residue from the clean headlight lenses with a paper towel dipped in warm water.
Using Wet Sanding Method to Clean Headlights
The wet sanding method is the most preferred permanent remedy for cleaning car headlights. Though the technique produces spectacular results, it’s time and labor-intensive according to New York’s Department of Health (..).
Wet Sanding Ingredients
- Paper towels
- A trash bag or plastic sheeting
- A bottle of isopropyl rubbing alcohol
- Three pieces of sandpaper
- 2000-3000 grit sandpaper
- A tin of carnauba paste wax
- A spray bottle of warm water
- Clear coat
- Painters’ tape
Start by covering the edges of the headlight with painters’ tape. Drench the headlight lenses with water and wet the sandpaper and move the sandpaper lightly over the lenses in a circular motion. Repeat the process with 2000-3000 grit sandpaper until it exhibits a hazy appearance.
Apply the rubbing alcohol onto a paper towel and wipe the lens to get rid of any natural oils. Cover any exposed paint area with plastic sheeting. Cut out the plastic sheeting around the headlight and tape around the headlights.
Spray the clear coat and allow it to dry for 24 hours before applying the second and third coat. Finally, apply a coat of carnauba wax to the headlight lenses allowing it to get near-dry before buffing it.
Using Headlight Restoration Kits
Apart from using various home cleaning solutions, headlight restoration kits can also remove fogginess. First, read reviews about customer experiences to help you decide if it’s the ideal method for you. Read the instructions for each product and compare it to using harsh techniques.
