Correct Methods for Defogging While Driving in Summer

Methods for defogging while driving in summer: 1. Open windows for air circulation: If the fog inside the car is not heavy, you can open a small gap in the side windows to allow air to circulate between the inside and outside of the car. This reduces the temperature difference and gradually dissipates the fog. The principle is similar to using the air conditioner to blow cold air, but it does not increase fuel consumption. However, this method has obvious drawbacks: it is not suitable during rain, snow, or on highways, and it lowers the temperature inside the car. 2. Air conditioning system: For most car owners, using the air conditioning system to defog is the most common method. Almost all cars have air vents under the front windshield. Simply adjust the air conditioning to the appropriate setting to use the airflow to defog. Turn on the fan and the cooling switch, and the cold air will quickly remove the fog on the windshield, providing immediate results. 3. Anti-fog spray: Special anti-fog sprays are available at auto parts stores, supermarkets, and other places. Spray the anti-fog agent on the inner surface of the car glass and wipe it clean. This not only removes dirt but also forms a protective film to prevent moisture from condensing into fog on the glass. One application of anti-fog spray can last for about ten days.
In summer, my go-to method for defogging while driving is to turn on the AC with cold air, directing the vents straight at the windshield while ensuring the A/C switch is on. This helps dry the air and quickly remove fog. If the fog is heavy, I slightly crack open a window to let fresh air in, reducing humidity inside the car. Avoid setting the AC too cold all at once, as a large temperature difference can worsen fogging. I usually keep the inner windshield clean by wiping it with a slightly damp cloth to prevent fog buildup. This simple and effective method has helped me solve countless issues over my ten years of driving, reducing distractions on the road. Remember to start with medium-low fan speed when turning on the AC, then adjust back to normal temperature after defogging—it saves energy and keeps you comfortable.
In summer, my priority for defogging is driving safety. The method involves activating the air conditioning in cooling mode, adjusting the vents to direct airflow only to the front windshield, and then turning on the A/C button to enhance the drying effect. When the fog is heavy, I slightly open the window to let in some air to assist in defogging. I pay special attention not to set the air conditioning temperature too low to avoid fog recurrence, and regularly clean the air filter and vents to ensure smooth ventilation, ensuring safe and smooth driving. From experience, this method is reliable and practical.
