Foggy Headlights? This WD-40 Trick Works—But There’s a Catch

Headlights help you drive at night and in low-visibility conditions. Driving with dirty, foggy, or yellow headlights can drastically limit your visibility. If your car has cloudy headlights, you’re not alone. In fact, it’s a very common issue in vehicles, especially in older models. A variety of factors, including oxidation, condensation, road debris, and sunlight exposure, can cause this cloudiness to occur.

Using WD-40 is a quick and easy way to restore the shine to your headlight lenses, however, it’s only a temporary solution.
