In winter when it snows, the front windshield inside the car becomes unclear. Does it need to be cleaned?

In winter when it snows, the front windshield inside the car becomes unclear because the low external temperature creates a temperature difference on the windshield, leading to fogging. Below are the specific reasons for the unclear windshield and solutions to address it: Specific reasons for the unclear windshield: When the outside temperature is low and the inside temperature is high, the temperature of the car windows also decreases. The moisture inside the car condenses into fog when it meets the cold windows. Additionally, on snowy days, the air is more humid. Opening and closing the car doors, as well as bringing in water from shoes, increases the moisture inside the car, making it more prone to fogging. Solutions for the unclear windshield: If the car has automatic air conditioning, simply turn on the auto mode button. For manual air conditioning, turn on the external circulation and adjust the air vent position knob to direct airflow toward the windshield.
