How to Deal with Fogging on the Exterior of the Car's Windshield?

[LaLane]

There are three main methods to deal with fogging on the exterior of the car's windshield. Below is a detailed introduction to these three methods: 1. Air Conditioning Defogging: Simply turn on the front window defogging mode, set the fan speed to maximum, and turn on the A/C switch. This is the simplest method. 2. Air Convection: By increasing air convection, the temperature difference between the inside and outside of the car is reduced, thereby weakening the conditions for fog formation. This method has a limited scope of application. 3. Defogging Agent: Just spray the defogging agent evenly on the glass surface. Its principle is to use surfactants to change the surface tension of water molecules, causing fog droplets to coalesce into larger water droplets that do not obstruct vision. This is a preventive method.
