How to Deal with Foggy Windshield in Summer?
2 Answers
In summer, if the windshield fogs up, you can turn on the front window defogging mode, then adjust the fan speed to the maximum, turn on the AC switch, and set the temperature to the lowest. The fog on the glass will disappear shortly. Alternatively, wiping the inside of the windshield with a cloth dipped in dish soap or a special anti-fog agent can also effectively prevent the glass from fogging up. Fogging on the outside of the windshield: This situation often occurs before a summer rainstorm when the air is hot and humid. Even if the temperature is not very high, it can still be very uncomfortable due to the high humidity, which prevents sweat from evaporating and absorbing heat, leading to poor human comfort. Driving with the air conditioning on in such weather can easily cause the windshield to fog up. This happens because the cool air from the car's AC lowers the temperature of the windshield, causing the water vapor in the outside air to condense upon contact with the cold windshield.
Windshield fogging in summer is a common issue caused by temperature differences. Having driven for over a decade, when encountering this situation, I first turn on the air conditioning to cool, adjust the airflow to blow towards the windshield, and use the external circulation mode to allow air flow for dehumidification. Opening the windows slightly can speed up ventilation, and the fog can clear in just a few minutes. Prevention is crucial. Every time I wash my car, I use glass cleaner to wipe the windows, keeping the surface smooth and less prone to condensation. I also keep an anti-fog spray in the car for emergencies. Safety is important too—don’t drive stubbornly in heavy fog; find a safe place to stop and handle it. Regularly check the humidity control inside the car, as excessive moisture can easily cause recurrence. These small habits have saved me a lot of trouble.
