The Best Way to Clean Headlights

In addition to having a clean headlight lens, this method will also keep your headlights shining.

  2. Then, we need to apply WD-40 to the entire headlight and wait for at least 10 mins to allow the chemical to break down the grime.
  3. Finish the process by wiping the headlights with a soft cloth in circular motions.
  4. Repeat the same process for a much polish result.

Tip 2: Make Headlights Clear with Baking Soda and Vinegar/Lemon


Baking soda with vinegar can be an effective DIY headlight cleaner. The combination will be a fix to your headlights’ problem without damaging your car’s paint.

  1. Make sure to remove dirt in the outer layers of the car’s headlights by using a clean rag and some dish soap.
  2. Then, mix baking soda and vinegar to make a cleaning paste.
  3. Then, cover the headlights with the cleaner and let it sit for 5 – 10 minutes.
  4. Make sure to wash off the remaining baking soda-vinegar mixture with water and a clean cloth.
  5.  For better results, apply elbow grease if you have any.

What if you don’t have a supply of vinegar at home? In this case, baking soda may also be partnered with lemon to make a good foggy headlight cleaner to get the same results.

For this mixture, it is preferable that for every lemon, 30 grams of baking soda will be used. Put the mixture in a container and apply using a microfiber or polishing cloth.

Tip 3: Fixing vehicle foggy headlights with toothpaste


Remember when you wanted to fix your foggy headlight but forgot to buy a restoration kit at the store? Don’t worry. A tube of good white toothpaste is all you need to solve your problem.

Toothpaste contains chemicals that act as abrasives and is very useful in scratch marks and grime on vehicle surfaces.

  1. Simply put an adequate amount of toothpaste into the car lights and let it sit for about 5-10 mins.
  2. It is important to gently wipe the surface in circular motions to properly incorporate the toothpaste and increase the effectiveness of this method.
  3. Using a clean cloth, you will need to remove the toothpaste residue afterward.

All these tasks can be repeated depending on the amount of fog in the vehicle’s light.
