How to Solve Fogging on the Outside of Car Windows on Rainy Days?
1 Answers
Fogging on the rear window after rain can be addressed using the following methods: 1. Air Conditioning Cooling for Defogging: The main causes of window fogging are low temperature and high humidity. Using the air conditioning cooling function can remove fog from the front windshield. However, if the humidity inside the car is too high, the effect may not be very noticeable. In such cases, slightly opening the windows can quickly reduce interior humidity. 2. Window Ventilation for Defogging: Opening the windows allows cold and hot air to circulate. If the fogging is not severe, slightly opening the side windows can create air convection inside the car, gradually equalizing the interior temperature with the outside temperature and dispersing the fog. The advantage is that it achieves the same effect as using the air conditioning without increasing fuel consumption. During extreme cold or rainy conditions, intermittently opening and closing the windows is recommended. This method is not suitable for severe fogging. 3. Anti-Fog Spray: Applying glass anti-fog spray forms a transparent hydrophobic ion film on the glass surface, preventing water droplets and fog from condensing. 4. Anti-Fog Cloth: When fogging occurs, wiping the windows with an anti-fog cloth can prevent further fogging, achieving the same effect as anti-fog spray. 5. Detergent-Based Anti-Fog Solutions: Mixing dish soap with water in a ratio of approximately 1:10 and applying it to the inside of the front and rear windshields with a cotton swab or soft cloth can prevent fogging. Alternatively, mixing household shampoo or body wash with water in a similar ratio and spraying it on the windows before driving can also prevent fogging.
