What are the methods for preventing fogging on car windows?

Methods for preventing fogging on car windows include: 1. Spraying anti-fog agents; 2. Turning on the air conditioning for cooling or heating; 3. Opening the windows to reduce the indoor temperature difference; 4. Wiping the car windows with a mixture of detergent and water. Car windows are essential components of a vehicle's body accessories, primarily serving a protective function. They are mainly categorized into: laminated glass, tempered glass, and zoned tempered glass. Car window maintenance methods: 1. Use glass cleaner appropriately; avoid using tap water to clean the windows, as it can easily scratch the glass; 2. Apply window film to the car windows, which can help with insulation, noise reduction, and anti-aging; 3. Purchase glass insurance for the vehicle to minimize losses in case of window breakage.

In the first few minutes after starting the car in winter, I usually turn on the air conditioner immediately and set it to the defogging mode. Both hot and cold air are effective, but cold air removes fog faster. Before each trip, I check if the wiper blades have aged and hardened, as worn-out blades can leave water streaks that cause fogging. I often use old newspapers dipped in dish soap to wipe the windshield back and forth, which keeps it fog-free for two to three days. Another trick is to lower the window slightly to allow air circulation, but be careful not to let cold air blow directly on your body to avoid catching a cold. If all else fails, buying a bottle of anti-fog spray and applying it to clean glass works well and lasts quite a while, saving a lot of hassle. Keeping a clean towel in the car is also a safe bet for sudden fogging—just wipe it off quickly.

I usually keep a bottle of anti-fog spray in my car. It's simple to use - just spray it on the windshield and wipe evenly with a dry cloth. The effect lasts about a week. Turning on the car's AC is the most direct solution - remember to press that defog button with the wavy arrow, then adjust cold or warm air according to temperature. When temperatures fluctuate or during rainy days, I'm extra careful not to keep windows completely closed for too long, otherwise moisture from breathing will accumulate on the glass and cause fogging. I've also noticed fogging happens more easily when smoking or traveling with pets - in such cases, it's safer to turn on some fresh air circulation. During car washes, I ask the staff to specifically treat windshield oil films, as regular cleaners won't remove them properly and fogging will still occur.

Fog prevention should address both interior and exterior. Exterior fogging can usually be resolved by turning on the wipers during rainy days. Interior fogging is more troublesome; it's best to preemptively turn on the air conditioner and direct it towards the windshield. Physical methods work quickly: after parking, open the windows for a while to let the moisture dissipate, and use a silicone anti-fog cloth to wipe the glass to keep it dry. Chemical treatments last longer: buy an anti-fog spray from the supermarket and apply it evenly as per the instructions—products containing alkyl sulfonate work best. There's also a handy life hack: rub the inner surface of the glass with a potato slice; the starch forms a protective film that prevents fogging for up to three hours. Window tinting also matters—nano anti-fog films are more expensive but offer long-term convenience.
