The Correct Method for Defogging While Driving in Summer?
4 Answers
Methods for defogging while driving in summer include using wipers with water spray and utilizing the air conditioning's cooling system. Below are detailed introductions to defogging: 1. Fogging on the outside of the car glass: You can directly use the wipers to clear it, but make sure to spray water while wiping; avoid dry wiping. Additionally, you can use the air conditioning's warm air for defogging, adjusting the air circulation mode to external circulation. Depending on the situation, activate the front and rear windshield defogging modes to eliminate the temperature difference between the glass and the outside. Remember not to use cold air, as it can worsen the situation. This method is also applicable for defogging car glass in winter. 2. Fogging on the inside of the car glass: Use the air conditioning's cooling system for defogging. First, turn on the A/C switch, then press the front windshield defogging button, set the temperature to the lowest, switch to internal circulation mode, and adjust the airflow. The fog on the front windshield will then clear. If you notice fog on the rear windshield and side mirrors, you can also activate the rear windshield defogging button.
I often encounter foggy windows when driving in summer, especially on rainy days or right after turning on the AC. The correct method is to press the defogger button as soon as the vehicle starts, turn the air direction control knob to the windshield position, then activate the A/C cooling mode, set the temperature lower, and increase the fan speed. At the same time, select the external circulation mode to let fresh air in; if it's not raining outside, slightly open the windows to assist ventilation, which can quickly balance the humidity inside and outside the car. Applying anti-fog spray in advance on the inner side of the glass provides excellent preventive effects. Fogging is mainly caused by condensation due to temperature differences, and cold air dehumidification is the most effective. I always remind myself not to wipe the windows with my hands, as it can easily distract attention and affect driving safety. Safety comes first, and clear visibility ensures a worry-free drive. After developing this habit, every long trip has become much more hassle-free.
As a car enthusiast, I emphasize the importance of the air conditioning system for summer defogging: turn on the A/C for cooling and dehumidification, select external circulation, and direct the fan toward the windshield. Cold air can quickly clear fog, ensuring clear visibility. A common misconception is using hot air or prolonged internal circulation, which can actually worsen fogging. Combine this with opening windows for ventilation to balance interior and exterior air; use anti-fog agents regularly for prevention. Vehicle air conditioning maintenance is crucial—regular checks ensure cooling efficiency. Driving with fogged windows is unsafe; slow down and pull over to address it rather than risking it. Prevention is more reliable than dealing with it. After years of driving, I've developed the good habit of activating defogging as soon as I get in the car.
Correct solution for summer window fogging: Press the defog button, turn on A/C cooling, increase the fan speed, and set the temperature lower. Adjust the air direction to blow at the windshield; turn on the external circulation or open the window slightly for assistance. Prevention can be done by pre-treating the glass with anti-fog spray. Fogging occurs due to large temperature differences, and cold air dehumidification is effective. The operation is simple but important, as blurred vision can easily lead to accidents. Safety first, maintaining ventilation is key.
