What are the methods to deal with fogging on car windows?

The methods to deal with fogging on car windows are: 1. Turn on the car's air conditioning system for cooling, directing cold air onto the fogged front windshield; 2. Mix detergent with water and apply it to the outside of the car window using degreasing cotton or a clean, soft cloth; 3. Open the sunroof or window to allow indoor air to circulate; 4. Install a window heating defogging function. The reasons for car window fogging are: 1. The temperature of the car window is below the dew point temperature; 2. There is a significant temperature difference between the inside and outside of the car. The functions of car windows are: 1. To shield from wind and rain, and to reduce noise; 2. To lower wind resistance and guide airflow; 3. To protect the safety of the passengers in the car.
Having driven for over a decade, I've noticed that window fogging often occurs during high humidity or significant temperature differences, such as on rainy days or in winter, when the temperature disparity between the inside and outside of the car causes moisture to condense on the windows. The most effective method I've found is to immediately turn on the air conditioning defogging function—the button that directs air to the windshield—which usually clears it up in just a few minutes. If there's no air conditioning, quickly opening the windows slightly to allow cross-ventilation can also disperse the fog rapidly. I always keep a bottle of anti-fog spray on hand, applying it to clean windows to form a protective film that prevents fogging. Another good trick is not to close the car door immediately after parking; instead, wait for the interior air to dry before locking up. In cold weather, using warm air for defogging works a bit better, but be careful not to direct the heat straight at your skin to avoid dryness. Above all, safety is paramount—never drive with obscured vision. I've tested all these methods, and they're very reliable.
