Should You Use Cold or Hot Air to Defog the Windshield in Winter?
1 Answers
Start the air conditioning, set the temperature to the heating mode, and switch the air conditioning to the defogging mode. Use the hot air produced by the heating system to dry the fog inside the car. Introduction to Air Conditioning Defogging: If your car has automatic air conditioning, defogging is very easy. Simply turn on the automatic air conditioning and set the mode switch to the defogging mode. For manual air conditioning, first adjust the airflow direction switch to the defogging mode. Remember one crucial point: when defogging, always switch the air conditioning to the external circulation mode to allow fresh outside air to enter the cabin. Setting the compressor and fan speed to the highest level can speed up the defogging process. If the side windows are not defogging quickly enough, it's best to close the two central air vents to direct the airflow from the side vents more effectively, which can help disperse the fog faster. You can also slightly open the windows to accelerate defogging. Using Specialized Defogging Products: In addition to using hot air for defogging, you can also use specialized defogging products. For example, certain defogging sprays can be evenly applied to the windows before use, forming a protective film on the glass that prevents fog from forming.
