How to Deal with Foggy Interior Glass?
2 Answers
Solutions for foggy car windows: 1. First, use a clean cloth to wipe off the fog on the windows. 2. Adjust the car window button to leave a small gap, allowing air circulation between the inside and outside of the car to reduce temperature differences and prevent fogging. 3. Start the car engine in neutral or park and warm up the car. 4. Once the water temperature gauge rises, turn on the car's air conditioning and press the window defogging button to dry the moisture on the windows with warm air. 5. Purchase a car-specific anti-fog spray or anti-fog towel from an auto parts store. First, clean the window surface with a clean cloth or anti-fog towel, then spray the product on the clean window surface to form a protective film that prevents fogging. 6. First, wipe the window surface with a clean cloth, then mix dish soap and water in a 1:10 ratio, shake well, and use a clean cloth to apply the mixture to the glass.
Foggy windows are a common issue when driving, especially during rainy or winter days when humidity inside the car combines with temperature changes to create a blurry mess. The quickest solution is to use the air conditioning defogger: after starting the car, turn the fan to maximum and direct it at the windshield—choose cold air in hot weather and warm air in cold weather, and the fog usually clears within seconds. Many new cars now come with a dedicated defog button for one-touch convenience. If you prefer not to use the AC to save fuel, cracking the windows for ventilation also helps, though this isn’t safe at high speeds, so slow down first. Remember not to wipe the glass with your hands, as fingerprints can make things worse—use a clean cloth instead. To maintain clear visibility, develop good habits: clean the glass promptly when it’s dirty and apply an anti-fog spray as a preventive measure.
