How to Defog a Car?

[Avery]

Methods for defogging and defrosting a car windshield are as follows: (1) Roll down the windows to allow air convection: Partially roll down the windows to let cold air from outside blow into the car, creating convection between hot and cold air. This reduces the temperature difference inside and outside the car, helping to eliminate frost and fog. If the weather is extremely cold, you can intermittently open and close the windows. (2) Use the air conditioning defogging system. The general steps are: 1. Adjust the "airflow mode" to "defog"; this mode mainly controls warm air to flow toward the windshield, the front windows near the rearview mirrors for both the driver and passenger. 2. Turn the "temperature control" knob to the red zone; this ensures the system outputs warm air. 3. Adjust the fan speed knob. To defog quickly, turn it to the maximum. Without airflow, the previous adjustments will not work. (3) Use a defogging agent.
