Home Remedies To Defog Your Headlights


Are you looking for some DIY home remedies to defog your car headlights? If you follow these tips, you will restore your headlights quickly without blowing a hole in your pocket. So let’s get straight into it! 


Deet is an insect repellent or a bug spray. It is pretty good for cleaning headlights. However, bear in mind that it is not good to use DEET frequently. Ensure to wipe it off instantaneously as the strong chemical composition of DEET can melt the plastic coating of your headlights.

Cleaning Process

This method is a bit more tricky than the other two methods. However, if you want to try this occasionally, then there’s no harm in it. Be careful while cleaning, and ensure that you have left no traces of DEET on the headlights. You can do so by cleaning it using vinegar or soap. 

Note:- Do not use DEET regularly for cleaning purposes. 

    • Begin with a relatively clean surface. 
    • Take cleaning wipes or a dry microfiber towel, spray a little insect repellent on it to dampen it. Do not spray directly on the headlight. 
    • Wipe off the lenses to remove the mist and fog.
    • Use the vinegar and soap mixture to make sure you remove all of the DEET from the headlights. 
    • Now clean the lenses using a dry towel for the final touch.

2. White Distilled Vinegar And Baking Soda

The easiest and quickest cleaning method is using white distilled vinegar along with baking soda. This method will take care of cloudiness, yellowness on the plastic surface, and hazing. 

Cleaning Process


    • Begin with a relatively clean surface.
    • Grab plain white distilled vinegar and pour ½ cup or 1 cup full of vinegar into a bowl, add two spoonfuls of baking soda, mix thoroughly to prepare a homemade cleaning solution. 
    • Take a clean microfiber towel, dip it into the solution, and wipe off the dirt on the lenses in a circular motion.
    • Use car shampoo to ensure it is extra clean and wash it off with water
    • Wipe off using a dry towel

Focus on the areas that are more yellow or cloudy. Repeat the process if you want to see sparkling clean, haze-free lenses. It is a very pocket-friendly home remedy, but it won’t turn your lenses as good as new, given the acute oxidation. 

3. Toothpaste

It is the most straightforward and handy method. You can’t use DEET frequently since it’s a chemical; you don’t want to get your hands into making a solution involving stinky vinegar? So, what’s left now? Toothpaste! Yes, you heard that right. So grab one small size toothpaste and a towel or a car wipe, spare towel, car shampoo or soapy water, and plain water.

Cleaning Process

    • Squeeze out a pea-sized ball of toothpaste on the wet towel; now rub the towel on the lenses in a circular motion. 
    • You can add more toothpaste if you need it and 
    • Rub the hazy surface gently to scrap out accumulated dirt and cloudiness with gentle hands. 
    • Now wash off the surface with car shampoo or soapy water.
    • Rinse it using plain water. Here, you could use a small spray bottle or a garden hose also. 
    • Lastly, wipe it off using a dry towel. 
    • Repeat the process for better results and apply a UV coat. 

Note:- Haziness, cloudiness, dirt, all of it will return if you do not seal the plastic surface of the headlight with a UV protection coat.   


You may have possibly suffered or experienced the issues that arise with foggy and cloudy headlights. Slowly and gradually, the polycarbonate surface of the headlight turns yellowish and hazy, given the ultraviolet rays and flying debris. These deposits on the lenses damage them and reduce the visibility on the road, especially at night or in stormy weather conditions. All of the above are quick fix hacks, and you do not need to run around in search of cleaning mediums as most of these are already available at your home.
