How to Use Car Heater in Winter Without Fogging Up Windows?
1 Answers
Methods to prevent car windows from fogging up when using the heater in winter: 1. When turning on the heater, activate the car's external air circulation to allow outside air to enter the vehicle. This facilitates air exchange between the interior and exterior, reducing the temperature difference inside and outside the car, thereby preventing window fogging. 2. Apply anti-fog spray. This method involves spraying the anti-fog solution onto the glass and then wiping it clean, which helps in removing fog and dirt. Reasons for window fogging when using the heater: Due to the temperature difference between the inside and outside of the car, the warmer interior causes moisture to condense on the inner surface of the windshield, forming fog.
