How to Solve Fogging on Car Windows in Summer?
4 Answers
You can use a clean cloth to wipe off the fog on the windows; adjust the car window button to leave a small gap, reducing the temperature difference to prevent fogging; you can also use the car's air conditioning system to defog, or use a detergent mixture method to remove fog. Here are some additional tips: 1. Proper use of the air conditioning system: First, turn on the recirculation mode to prevent outside moisture from entering the car, then turn on the air conditioning to lower the humidity inside the car. Depending on the situation, activate the front or rear window defogging mode, set the fan speed to maximum, and the temperature to the lowest setting for quick defogging. 2. Specialized anti-fog products: Spray evenly on the windows and wipe clean before each use to form a transparent protective film that prevents fogging. One application can last about 10 to 15 days, depending on the product's effectiveness. Buying anti-fog spray is a convenient but not cost-effective solution, as its effects are short-lived. 3. Leave a small gap in the window: If the fog is not heavy, you can open a small gap on both sides of the windows to allow air circulation 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 same effect as using the air conditioning without increasing fuel consumption. However, during winter or rainy days, it is recommended to intermittently open and close the windows.
I've been driving for over a decade, and fogging on car windows in summer is very common, mainly caused by the temperature difference between inside and outside the car combined with high air humidity. Turning on the air conditioning's defogging mode as soon as you get in the car is the most effective solution—adjust it to blow cold air directly at the windshield, and the fog will clear up in minutes. If the AC isn’t strong enough, slightly opening the windows to allow air circulation helps avoid stuffiness inside. Additionally, cleaning the windows in advance is crucial, as dirt makes fog more likely to form. I regularly use anti-fog spray to wipe the glass, which helps prevent fogging. Remember not to park under direct sunlight for too long, as high interior temperatures make fogging more likely. Also, check the AC filter periodically—if it’s clogged, defogging becomes much less effective. Developing these small habits ensures clearer visibility and safer driving.
I often watch car tips on short videos and have some insights on dealing with foggy windows in summer. The reason for fogging is simple—it's caused by high temperature and humidity leading to water vapor condensing on the glass. The easiest method is to turn on the cold air defogging function immediately after starting the car, or slightly open the window for a few seconds to balance the temperature. I also like using a mobile app to connect to the car system and pre-start the air conditioning, avoiding a foggy interior when getting in. Buying a special anti-fog spray for windshields is also a good idea—just a light spray and wipe for lasting clarity. Be careful not to use hot air, as that will make the fog worse. Adding a glass coating treatment during car washes can also reduce the frequency of fogging. In short, try a few methods to find what works best for you, and always prioritize safety—don't rush to drive.
I find it quite annoying when the car windows fog up in summer, usually caused by the temperature difference between inside and outside when getting in the car. I usually turn on the defrost button with the AC blowing directly at the windshield, and adjusting the airflow direction straight ahead makes it more efficient. If the AC feels uncomfortable, I briefly roll down the windows for ventilation, and the fog disappears quickly once the air circulates. Avoid using a wet towel to wipe the windows as it can make the problem worse. Keeping the car's AC filter clean can prevent many issues. Using desiccants in the car or regular ventilation also helps. With a few simple steps, the fog clears up, and clear visibility is the most important thing.
