The Unexpected Question: Can Bug Spray Help Clean Headlights?

The idea of using bug spray for cleaning headlights might seem strange, but it stems from the properties of the spray itself. Bug spray often contains solvents and chemicals designed to dissolve substances like insect residue. These same properties could potentially break down the grime, oxidation, and yellowing that accumulates on headlight lenses. This article will provide an in-depth exploration of this topic, examining the different types of bug spray, how they work, and if they’re a viable option for cleaning your car’s headlights.

Understanding Headlight Materials

Most modern headlights are made from a type of plastic called polycarbonate. Polycarbonate is chosen for its durability and resistance to impact.
