How to Deal with Fogging on the Outside of the Front Windshield When Driving in Summer Rain?
3 Answers
Turn on the air conditioning and direct it to blow onto the front windshield. The cold air will quickly disperse the fog, providing a fast and direct solution. Using hot air to blow on the glass can also effectively remove the fog. You can use the windshield wipers directly, but remember to spray water while wiping to avoid dry wiping. Before heading out, simply spray it evenly on the surface of the car window glass and wipe it clean with a dry towel.
I've experienced fogging on the front windshield when driving in summer rain several times. This is mainly caused by raindrops hitting the windshield, combined with high summer humidity and temperature differences between inside and outside the car leading to condensation. My suggestion is to first turn on the wipers to clear surface water droplets, as they can quickly remove accumulated raindrops. Then, activate the fan to blow air directly at the windshield; if there's an AC function, turn it on to dehumidify and cool. At the same time, adjust the car's air conditioning temperature slightly lower than outside to reduce temperature differences. If fog persists, don't rush to drive—find a safe place to park and wipe the glass surface with a clean, dry cloth. Make it a habit to check if the wipers are worn before each trip and ensure the glass is free of stains to prevent more frequent fogging. Visibility is crucial when driving, so timely action ensures safety. You can also try applying anti-fog spray to the glass regularly—it's quite convenient and preventive. Remember, small oversights can lead to big risks, so pay extra attention to details when driving in the rain.
Dealing with fog requires some technical know-how. When driving in rain and fog, the issue often stems from water droplets forming as rain and dust cool down. The first step is to press the car's defogging button, which automatically directs the fan toward the windshield. Turning on the AC system is a must—it absorbs moisture and dries the air. After running the fan at maximum speed for a few seconds, dial it back to medium to avoid excessive noise. If the car has automatic climate control, switching to Low mode yields better results. I always remind myself to check if the wipers are worn out, as old blades can worsen fogging. Also, keep the temperature difference between inside and outside below 5 degrees to prevent condensation. Long-term use of anti-fog coatings can also help prevent issues. Don’t rush the process—pull over safely and ensure all systems are functioning properly before continuing. With frequent summer driving, these basic maintenance steps are essential.
