How to Defog Car Windows on Rainy Days?
2 Answers
To defog car windows on rainy days, you can follow these methods: 1. If there is only a slight fog, simply use a highly absorbent towel to gently wipe the windows. If the fog reappears after wiping, you can lower the window slightly to open a small gap, reducing the temperature difference between the inside and outside of the car, and the fog will gradually disappear. 2. You can also use the air conditioning to defog the windows. After turning on the air conditioning, use the recirculation mode and adjust the air vents to blow toward the windows. 3. If the rear window fogs up, you can press the defogging switch to warm the glass using the heating elements (red lines) on the rear window.
Removing fog from car windows on rainy days is actually quite simple, and I have a solution. I remember one rainy day when I was driving, the entire windshield was fogged up, making visibility dangerously blurry. I immediately turned on the air conditioning in cooling mode, set the fan speed to the highest, directed the airflow straight at the windshield, and also turned on the external circulation to let dry air in. This dehumidifying effect worked quickly, and the fog disappeared in no time. In winter, you can use warm air, but it works a bit slower. The rear window has a heating wire button—just press it to generate heat and remove fog. For prevention, you can spray some anti-fog solution or wipe the windows with soapy water. Fogging mainly occurs because moisture inside the car condenses on the cold glass, so balancing the temperature is key. I also make it a habit to check the air conditioning filter before driving to ensure smooth ventilation and reduce recurrence.
