What are the methods to defog car windows?

[MacJoy]

Methods to defog car windows are: 1. When the fog is light, open the car windows. When the temperature inside and outside the car becomes similar, the fog will dissipate; 2. Turn on the car's air conditioning in cooling mode; 3. Turn on the heating system before driving; 4. Activate the car's defogging function; 5. Apply a mixture of dish soap and water or soapy water as an anti-fog agent on the windows, or place a dehumidifying box for wardrobes inside the car. Fog forms due to the temperature difference between the inside and outside of the car. Since the temperature inside the car is relatively higher, when the warm air inside meets the cold car windows, the moisture in the air condenses, covering the windows with a layer of mist. This significantly obstructs the driver's view, making the road ahead appear blurry. Effective defogging methods are essential for safe and efficient driving.
