How to Deal with Foggy Windows in an Audi?

[VanFinley]

Here are the solutions for foggy windows in an Audi: 1. Proper use of the air conditioning system: After parking the car, turn on the air conditioner, adjust the temperature control button to the warm air direction, and then press the defrost button to use the warm air from the air conditioner to dry the fog on the windshield. When defogging, you can switch the air conditioner to external circulation to allow fresh air from outside to enter the cabin. Setting the compressor and fan speed to 25°C or higher can speed up the defogging process. 2. Use specialized anti-fog products: Before each use, spray evenly on the windows and wipe clean, forming a transparent protective film on the glass to prevent fog formation. One application can last for about ten days to half a month, depending on the product's effectiveness. Summary: Buying anti-fog agents is a convenient but short-term solution with limited cost-effectiveness. 3. Open windows for air convection: If the fog is not heavy, you can open a small gap in the side windows to allow air convection inside the car. This will gradually equalize the temperature inside and outside the car, causing the fog to dissipate. The advantage is that it achieves the effect of using the air conditioner without increasing fuel consumption. However, during severe cold or rain, it is recommended to intermittently open and close the windows. 4. Use dish soap with a dry cloth: Mix dish soap with water (ratio of 1:6), apply evenly to the interior glass with a sponge, and wipe dry with a car towel after it dries, leaving no watermarks.
