How to Remove Fog from Car Windows on Rainy Days?

[Rosalie]

Methods to remove fog from car windows on rainy days are as follows: 1. Open windows for air convection: If the fog inside the car is not heavy, you can open the windows slightly on both sides to allow air convection between the inside and outside of the car. This reduces the temperature difference and gradually dissipates the fog. The principle of this method is the same as using the air conditioner's cold air, but it does not increase fuel consumption. 2. Air conditioning system: For most car owners, using the air conditioning system to defog is the most common method. Almost all cars on the market have air vents under the front windshield. Simply adjust the air conditioning to the appropriate setting to use the air flow to remove fog. Both cold and warm air have their pros and cons. If you need to hit the road quickly, cold air can serve as an emergency solution, but warm air is generally recommended for most situations. 3. Anti-fog spray: Spray the anti-fog agent onto the inner surface of the car window and wipe it clean. This not only removes dirt from the glass but also forms a protective film to prevent moisture from condensing on the glass and forming a fog layer. One application can prevent fog for about ten days.
