Possible Causes of Cloudy Headlights

Before we explore how you can use WD 40 to clean headlights, you must first know the factors causing the headlight to have that yellow hue and the build-up of grime. In the early 1980s when the car manufacturers still used glass for headlights, the issue of yellowed hazy headlights did not occur. But the manufacturers decided to change it to polycarbonate glass or plastic fiber in replacement to the glass that can be broken easily.

Polycarbonate glass goes through oxidation when exposed to ultraviolet rays (UV rays), causing it to lose its clarity over prolonged exposure to UV rays. In the case of headlights, cars are exposed to the sun and extreme temperatures most of the time which causes the headlights to oxidize and turn yellow. Air pollution and acid rain can also contribute to the problem.

Signs of dirt and wearing should not be surprising on headlights. These are located in the front, first to face all those dirt, bugs, and other road debris you encounter while on the road. Having oxidized headlights is not only an unpleasant view of a car but, in addition, it can also cause a threat to the safety of the one driving the vehicle and the safety of other drivers on the road. Instead of casting a tight beam when in use in front of the car as a headlight is supposedly designed, foggy and oxidized headlights can scatter light that can affect the other driver’s visibility. To prevent this from happening, listed below is the quick and step-by-step guide to using WD 40 to clean headlights.


Steps on Using WD 40 to Clean Headlights:

  1. Before starting, you need to make sure that the area to be cleaned is free from any surface dirt (waxy deposits that stick on the surface) that might scratch the headlight. Remove the dirt on the surface and muck on the headlights by rinsing with water and using a water hose is a good option. You can also wipe them with a damp cloth but do it carefully. The last thing you need is to add more scratches to the lens.

4. After making sure that the surrounding area of the headlight is now covered, apply a liberal layer (or at least two sprays) of WD 40 to clean headlights. Let it stay in contact for 5 to 10 minutes. The product is designed to get under any built-up dirt. In this way, it will save you the extra effort of aggressive rubbing. Using other cleaning products requires substantial time in rubbing. This will make the next step easier.
