What to Do When the Outside of the Windshield Fogs Up in the Morning?

Turn on the front window defogging mode, set the fan speed to maximum, turn on the A/C switch, and then adjust the temperature to the lowest setting. Opening the windows can increase air convection, reduce the temperature difference between the inside and outside of the car, and weaken the conditions for fog formation. Simply spray it evenly on the glass surface and then wipe it clean with a dry towel. Mix dish soap and water in a 1:6 ratio, put it in a bottle, and spray and wipe it before traveling to prevent fogging.

It's really annoying when the windshield fogs up on the outside in the morning, especially during winter or after rain when humidity is high. Here's what I do: start the engine, don't rush to drive off immediately, turn the air conditioning to the highest temperature with maximum fan speed, and let it blow directly onto the windshield for a few minutes. This method works effectively because the hot air quickly heats the glass surface, naturally dissipating the fog. If I'm in a hurry, I slightly open the windows to allow air circulation inside the car and gently press the wipers to remove condensation. For regular maintenance, I recommend parking in a dry spot, avoiding areas under trees to prevent water droplets from leaves, and regularly cleaning the glass also helps. Applying anti-fog spray on the exterior glass forms a protective layer, which is quite effective in preventing fogging. Safe driving is paramount—never risk driving with poor visibility. These small habits make driving much safer.

As a driver, safety is the top priority. When the windows fog up, I first warm up the car and turn on the heater at maximum power to blow on the windshield. After a few minutes, the fog disappears, which is time-saving and efficient. Wipers can also assist in clearing, but the action should be gentle to prevent damage. Prevention is key: park in a garage or use a waterproof cover to block rain, avoid covering with wet cloth at night to prevent increased humidity; when cleaning the glass, use professional cleaners to remove dirt and maintain a smooth surface to reduce fogging. If it's humid in the summer morning, start the car a few minutes earlier to let the defroster work more quickly. I've been doing this for years, ensuring clear visibility while driving and protecting my family's safety as a basic responsibility. Remember to cultivate these small measures for smoother driving.

This issue stems from temperature and humidity differences; fog forms when the glass is cold and the air is humid. To address it, I simply turn on the heater at maximum intensity to blow air onto the windshield, resolving it within minutes. Using the external air circulation helps accelerate air drying, while gently activating the wipers can assist in removing water droplets. For prevention, anti-fog sprays are highly effective, and choosing a dry parking spot is also crucial. From a safety perspective, never take this lightly.
