The Truth About Using Bug Spray to Clean Headlights: Why It’s a Risky Shortcut
If you've come across the popular internet hack suggesting you use bug spray to clean your car’s headlights, you might be tempted to try it. The idea is simple: spray it on, wipe it off, and your headlights will magically become clear again. But before you reach for that can of bug spray, it’s important to understand the real impact this method can have on your vehicle.
Bug sprays like Off contain DEET, a chemical designed to repel insects. While DEET is effective for its intended purpose, it’s also a harsh solvent that can damage certain materials, including the polycarbonate plastic used in most headlight lenses. When you apply bug spray to your headlights, DEET melts the top layer of the lens, removing some oxidation and temporarily improving clarity. However, this is where the problems begin.
The clarity you achieve with bug spray is misleadingly temporary. DEET not only removes oxidation but also strips away the UV protective coating that manufacturers apply to headlights. This coating is crucial for preventing your headlights from turning yellow or cloudy again. Without it, the plastic lens is exposed to UV rays, causing it to degrade much faster. As a result, your headlights will likely become cloudy again within days or weeks, and the damage may be even worse than before.
Moreover, the DEET can roughen the surface of the lens, making it more susceptible to scratches and further damage. What started as a quick fix can lead to more costly and time-consuming repairs down the road.
Instead of relying on risky shortcuts like bug spray, consider proper headlight restoration methods. A professional restoration will remove the oxidation, smooth the lens, and apply a new UV protective coating, ensuring your headlights stay clear for much longer.
In conclusion, while using bug spray might seem like an easy solution, it’s one that can ultimately cause more harm than good. To keep your headlights in top condition, skip the bug spray and opt for a professional restoration that protects and preserves your vehicle's lights.
