What to Do When Car Windows Easily Fog Up?
2 Answers
Methods to deal with easily fogged-up car windows include: 1. Open both side windows; 2. Turn on the air conditioning's external circulation; 3. Adjust the air vents to defogging mode; 4. In winter, use the air conditioning's cooling and dehumidifying function to reduce air humidity; 5. In summer, use methods to reduce temperature differences for removal; 6. Wipe with a cloth dipped in dishwashing liquid or soapy water. Methods to prevent car windows from fogging up include: 1. Use anti-fog wipes for cleaning; 2. Apply anti-fog spray in advance. Car windows easily fog up due to the temperature difference between the inside and outside of the vehicle, where the temperature inside the cabin is higher than outside, causing moisture inside the cabin to condense on the inner windshield and form fog.
I've encountered window fogging many times myself. As a commuter who drives frequently, I find the most effective method is to immediately turn the fan to maximum speed, directing the airflow toward the windshield. Don't forget to turn on the AC with either cold air or the defogging mode to quickly remove the condensation. The root cause is simply high humidity inside the car or significant temperature differences between inside and outside, such as during rainy days or when breathing in winter. For short drives, I usually turn on the AC in advance to pre-condition the glass and avoid blurred vision when starting. Regular maintenance-wise, periodically cleaning the interior side of the glass is crucial, as grease buildup can worsen fogging. If the fogging becomes severe, temporarily stopping to open windows for ventilation is safer. Bottom line: never wait until it causes problems to address this issue.
