How to fix foggy headlights at home

Are your car headlights not as bright as they used to be, or perhaps you’re worried about the condensation on them? Well, we have the solution for you as we teach you how to clean your foggy headlights. It’s important to note, you could wash your car every week, use the best products on the market to wipe it down after it pours, and even park it and store it in a garage at every possible opportunity, but chances are that the headlights would still become foggy and blurry after a period of time. As the fog builds up, it can drastically impair the effectiveness of your car’s actual bulbs, which therefore makes it harder to see, especially at night. Therefore, foggy headlights should be addressed as quickly as possible.

Thanks to WD-40®, this guide will take you through the necessary steps to help you clean foggy headlights and get them working clearly again. Cleaning the gunk off your headlights is simple and an incredibly easy DIY job that you can complete with things you probably have at home with everyday household items. Of course, there are specialist all-in-one kits you can purchase over the counter that can get the job done, but all this task really requires is some proper elbow grease.

  • WD-40 Multi-Use Product

  • Clean cloth

If you want a quick fix for how to clean oxidized headlights, then the WD-40 product is a great option. However, it might not prove to be a suitable long-lasting solution for headlight restoration.

Prep your car for headlight defogging by protectively tapping off the area around your front lights. Mix a bucket of water with car shampoo (or liquid dish soap) and use our premium wash mitt to clean and ready the surface for the WD-40 lubricant. 

Shake the can of WD-40 and spray the product onto the headlight lens, avoiding hitting unprotected car areas. Then, carefully but thoroughly wash off the lubricant with another clean wash mitt or rag with the bucket solution. Once all the oil has been removed, try it off with the CleanTools Absorber® and remove the tape (without spreading any lubricant left on top of it).

Use WD-40 sparingly: relying on this oil product too often could blur or burn out the bulb of your headlights, so be sure you wash it off completely every time it’s used.

In addition to purchasing an at-home headlight restoration kit or booking a professional cleaning, CleanTools has listed several DIY processes you can take to maintain the high visibility of your headlights for maximum safety on the road. 

Based on the descriptions in the above section, we’ve compiled a list of the products you’ll need to get this job done right, depending on your choice of cleaning method:

  • Toothpaste (containing abrasives)

  • Vinegar and baking soda

  • WD-40 spray

  • Bucket

  • Water

  • Tape

  • Plastic Sheeting

CleanTools has two products that pair together perfectly for all your car wash needs. Our Premium Wash Mitt, made from a wool, polyester, and nylon blend, can hold more water longer to keep your hand on your car and instead of in your bucket. We recommend you keep a separate mitt for different surfaces of your car so you can avoid transferring abrasive particles from one area to another.


Our high-quality, dependable, and gentle mitt can be followed up by The Absorber®. This incredible drying product is made of Poly Vinyl Alcohol (PVA). It has the unmatched ability to dry your car in noticeably fewer wipes!
