What to Do When There's Fog Inside the Car with the Air Conditioning On?
2 Answers
Turn on the "external circulation" mode of the air conditioning. External circulation draws outside air into the car, preventing fog from forming. Turn on the "defogging" mode of the air conditioning. At this time, the air conditioning airflow will blow toward the windows, drying the fog. After spraying defogging agent on the glass, a protective film will form on the glass, preventing moisture from condensing on the glass and forming a fog layer. Mix dishwashing liquid and water in a 1:10 ratio and apply it to the inside of the glass with a soft cloth. You can slightly open the windows; after the air circulates, the fog will disappear.
I've always been an enthusiastic driver and noticed that fogging inside the car when the AC is on is quite common, mainly because it's cold outside and warm inside, causing moisture in the air to condense on the windows. Handling it is simple: just press the defog button immediately—most cars have this feature, usually involving turning on the AC and adjusting the vents to blow at the windshield. If there's no such button, turn on the A/C and switch to external air circulation, increasing the fan speed. Regularly cleaning the interior of the windows is important, as dirt can worsen fogging. Remember to warm up the car for a few minutes; the fogging will reduce as the temperature difference decreases. Be extra cautious on rainy days—I always keep a cloth handy for quick wipes. Regular maintenance of the AC system is also crucial, as a dirty filter can affect dehumidification. In short, this issue isn't hard to solve; timely action ensures driving safety.
