How to Remove Fog Inside Car Headlights?

[Hank]

To remove fog inside car headlights, turn on the headlights and high beams. After about 20 minutes, the fog inside the headlights will gradually disappear. It's important to avoid using high-temperature baking methods, as headlight materials are typically made of plastic. Excessive heat can cause the headlight surface to soften or deform. Generally, moisture inside the headlights will evaporate quickly under normal usage or sunlight exposure. If water frequently accumulates inside the headlights, it may indicate a cracked dust cover, allowing water to enter and form fog inside the lens. In such cases, it's advisable to have the headlight assembly inspected at a repair shop.
