How to Deal with Foggy Windows?
2 Answers
Solutions for foggy windows: 1. Turn on the front window defogging mode, set the fan speed to maximum, press the AC button, and adjust the temperature to the lowest setting; 2. Some car models have electric heating functions for the rear windshield and side mirrors—simply press the switch, and it will take about a minute to clear; 3. Opening the windows can increase air circulation, reduce the temperature difference inside and outside the car, and weaken the conditions for fog formation; 4. Take preventive measures in advance by evenly spraying anti-fog solution on the glass surface and wiping it clean with a dry towel; 5. Mix dish soap and water in a 1:6 ratio, pour it into a bottle, and spray and wipe the windows before driving; 6. Warm up the engine, wait for the water temperature to rise before turning on the heater, set the fan speed to maximum, and activate the front window defogging mode.
Having driven for many years, I find dealing with fogged-up windows quite simple—it's mainly caused by moisture inside the car condensing on the cold glass. The primary method is to turn on the A/C and direct cold air toward the windshield—cold air absorbs moisture quickly, clearing the fog in seconds. If you dislike the cold, warm the air first before switching. Most cars come with a defog button that automatically adjusts the airflow direction for convenience. Opening windows for ventilation also works, especially when the outside air is dry, but be mindful of driving safety to avoid distractions. For prevention, I regularly clean interior window grease to reduce fogging risks; applying anti-fog treatments is another good solution. When fogging occurs, don’t panic—slow down, pull over, and handle it safely without wiping haphazardly to avoid obstructing your view. Before parking, slightly open windows to release moisture and prevent long-term buildup. These tips, learned from daily driving, are quick, effective, and ensure a smooth, safe ride.
