Cleaning foggy headlights is essential for maintaining optimal visibility and safety while driving. Over time, headlights can become cloudy due to oxidation, dirt, and UV exposure. Fortunately, you can restore them to their original clarity with some simple methods and tools.

Why Do Headlights Get Foggy?

Headlights often become foggy due to oxidation. The polycarbonate plastic used in most headlights is durable but prone to UV damage, leading to a cloudy appearance. Other factors include:

• Dirt and grime: Road debris and pollutants can accumulate on the lens.
• Water vapor: Moisture can seep into the headlight housing, causing fogging from within.
