You can use a clean cloth to wipe off the fog on the windows; adjust the car window button to leave a small gap, reducing the temperature difference to prevent fogging; you can also use the car's air conditioning system to defog, or use a detergent mixture method to remove fog. Here are some additional tips: 1. Proper use of the air conditioning system: First, turn on the recirculation mode to prevent outside moisture from entering the car, then turn on the air conditioning to lower the humidity inside the car. Depending on the situation, activate the front or rear window defogging mode, set the fan speed to maximum, and the temperature to the lowest setting for quick defogging. 2. Specialized anti-fog products: Spray evenly on the windows and wipe clean before each use to form a transparent protective film that prevents fogging. One application can last about 10 to 15 days, depending on the product's effectiveness. Buying anti-fog spray is a convenient but not cost-effective solution, as its effects are short-lived. 3. Leave a small gap in the window: If the fog is not heavy, you can open a small gap on both sides of the windows to allow air circulation inside the car. This will gradually equalize the temperature inside and outside the car, causing the fog to dissipate. The advantage is that it achieves the same effect as using the air conditioning without increasing fuel consumption. However, during winter or rainy days, it is recommended to intermittently open and close the windows.
