What are the solutions for foggy car windows?

Solutions for foggy car windows include: 1. Use defogging spray to remove fog by evenly spraying it on the glass surface and wiping it clean with a dry towel; 2. Turn on the windshield wipers by setting them to a low speed and letting them run until the fog disappears; 3. Change the air source. Most cars have buttons to either recirculate the air inside the car or draw fresh air from outside; 4. Lower the temperature inside the car. Fog is caused by temperature differences, so matching the interior temperature with the exterior temperature can reduce fog. Increase the car fan setting and lower the temperature as much as possible.
Over the years of driving, I've frequently encountered the issue of foggy windows, especially during rainy days or in winter when temperature differences are significant. The solution is quite simple: first, activate the defogging mode of the car's air conditioning. Both warm and cold air can be effective—warm air is more comfortable but slower at clearing fog, while cold air dehumidifies quickly but lowers the temperature. Adjust the ventilation direction to blow directly onto the glass. If the air conditioning isn't effective, slightly opening the windows to allow airflow can balance the humidity inside and outside, quickly dissipating the fog, though this may increase noise from the wind. I usually keep a bottle of anti-fog spray handy to wipe the windows periodically, which helps prevent fogging. Regularly cleaning the glass to avoid oil film buildup is also beneficial. Avoid leaving wet umbrellas or clothes in the car to prevent moisture accumulation. Foggy windows obstruct visibility and are dangerous; on highways, I slow down and address the issue promptly. Long-term maintenance of the air conditioning filter can prevent malfunctions, ensuring a comfortable and safe journey.
