Understanding Foggy Windows

Before diving into the solutions, it’s crucial to understand what causes foggy windows. Fog is essentially formed when moisture in the air condenses on a cooler surface, like your car windows. This happens especially in humid conditions or when there is a significant temperature difference between the inside and outside of your vehicle.

Foggy windows are caused by tiny water droplets that cling to the glass, obstructing your view. The key to preventing fog is either to remove the moisture from the air or to create a barrier between the glass and the moist air. Let’s explore both methods. So how to stop car windows from fogging up?

Two Methods to Prevent Foggy Windows

The two methods can work together. The first one is a standard air conditioning and ventilation method used by everyone.
