What to Do When There's Fog Inside the Car Windows?

[McLayla]

Solutions for fog inside the car windows: 1. Open windows for air circulation. When the fog is not too heavy, you can open a crack in the windows on both sides to allow outside air to circulate, reducing the temperature difference and making the fog disappear; 2. Press the front windshield defogging button on the central control panel and adjust the air vents to face the front windshield; 3. After the fog disappears, you can turn off the AC button, reduce the fan speed slightly, and switch to warm air blowing at the glass; 4. Spray defogging agent evenly onto a soft cloth and wipe the front windshield, or spray it directly onto the glass.

I used to experience foggy windows quite often while driving, especially on rainy days or during winter when there's a significant temperature difference between the inside and outside. I usually turn on the air conditioning's defogging mode immediately—the fan icon function works really well. Setting it to blow cold air towards the windshield quickly clears the fog. If it's cold outside, try using the heater along with the defogging mode, and the fog will dissipate after a few minutes. Make sure to direct the vents toward the glass and select the external air circulation mode to let dry air in. Wiping the glass is also effective, but use a dry cloth to gently clean the inside—avoid making it wet, as that could worsen the problem. Cracking the window slightly to improve airflow can help prevent fogging. When parking, leave a small gap in the window to let moisture escape, and avoid leaving damp items like umbrellas or wet clothes inside to minimize the issue. Foggy windows while driving can be dangerous, so always pull over to handle it safely.

As a driver, safety comes first when the car windows fog up. Avoid making hasty adjustments while driving. I usually activate the defogging system or manually adjust the air conditioning vents towards the windows. Cold air removes fog quickly, while warm air is suitable for low temperatures. Check the interior humidity control to ensure proper ventilation. Gently wiping the inside of the windows with a clean cloth can help, but avoid using a wet cloth as it may worsen the fogging. For prevention, reduce sources of moisture inside the car, such as wet umbrellas or damp carpets, by using the heater to dry them out and bringing in fresh air through circulation. On rainy days, it's especially important to turn on the air conditioning in advance to maintain dryness. Rear windows are also prone to fogging, so handle them with extra care. Long-term maintenance includes cleaning the filters to ensure the defogging function works properly.

Foggy windows always obstruct my view, so I immediately turn on the air conditioning defogging mode or manually adjust the air vents. Cold air defogs the fastest, but hot air is also effective—it clears up after a while. Wipe the inside of the glass with a dry cloth to avoid water droplets. Reduce moisture sources like wet umbrellas or spilled drink bottles, and opening the windows for ventilation helps. Remember to control the humidity inside the car and replace the cabin air filter regularly.
