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

This is the simplest method: just turn on the front window defogging mode, set the fan speed to maximum, turn on the A/C switch, and then adjust the temperature to the lowest setting. This method is suitable for very few situations. Opening the window can increase air convection and reduce the temperature difference between the inside and outside of the car. When using it, simply spray it evenly on the glass surface and then wipe it clean with a dry towel.

I often encounter the problem of fogging on the outside of the glass while driving, especially during autumn and winter or on rainy days. This happens because the temperature outside the car is too low, and there is moisture inside the car, causing water droplets to condense on the windshield. The quickest way to deal with this issue is to turn on the windshield wipers to quickly wipe away the fog and moisture. Then, adjust the air conditioning settings to defrost mode or turn on the cold air mode, directing it toward the glass area to reduce humidity inside the car and prevent fog buildup. If the problem persists, it's advisable to safely pull over and wipe the glass with a clean cloth or apply an anti-fog spray for prevention. I also make sure to regularly check the air conditioning system to ensure the drainage pipes are not clogged, preventing the issue from worsening. In short, maintaining clear visibility while driving is crucial for safety.

Having driven for decades, I've encountered fogging on the outside of the windshield quite often, especially when the weather turns cooler. In practice, I immediately use the wipers to clear visible fog and adjust the air conditioning to the external circulation plus cold air mode to effectively expel interior moisture. If the fog persists, I find a safe spot to pull over and wipe the glass surface. For prevention, I've developed the habit of regular air conditioning maintenance, such as replacing filters and servicing the compressor, to avoid reduced cooling efficiency leading to increased humidity. These simple steps significantly enhance driving safety and make the journey smoother and more reassuring.

As a new driver, I recently discovered how to deal with fogging on the outside of the windshield. In such cases, I first use the wipers to clear surface water droplets; then, I adjust the air conditioning to blow cold air onto the windshield, which usually works within about a minute. Additionally, keeping a bottle of anti-fog spray in the car is helpful—a quick spray can prevent condensation. If the issue occurs frequently, it's best to check if the air conditioning is leaking. A simple fix can prevent the fog from affecting your driving mood.
