How to Defog a Car on Rainy Days?

[MacJudah]

Methods to defog a car on rainy days include: 1. Using air conditioning for defogging—turn on the AC and direct cold air toward the windshield to utilize the dehumidification function and remove fog; 2. Using detergent-based anti-fog solutions; 3. Applying anti-fog spray—spray it on the fogged windshield and wipe dry with a cloth for immediate clarity; 4. Installing rain deflectors—these use aerodynamic channels to reduce wind resistance and direct airflow toward the side mirrors, speeding up evaporation; 5. Using the external air circulation mode; 6. Activating the rear window defroster; 7. Slightly opening the window to allow air convection and reduce temperature differences.
