How to Deal with Fogging on the Outside of Car Windows on Rainy Days?

[WilliamLynn]

You can slightly open the car window to quickly reduce the humidity inside the car. You can open a small gap on both side windows to allow air convection inside the car. This will gradually bring the interior temperature closer to the outside temperature, and the fog will dissipate. Using a glass anti-fog agent can form a transparent hydrophobic ion film on the glass surface, preventing water droplets and fog from condensing. When fogging occurs, wiping with an anti-fog cloth can prevent further fogging. Mix dishwashing liquid. The ratio of dishwashing liquid to water should be about 1:10. Then, use absorbent cotton to apply it to the inside of the front and rear windshields.
