What to Do When the Outside of the Front Windshield Fogs Up?

Here are the methods to deal with fog on the outside of the front windshield: 1. Use the car's built-in air conditioning system by turning on the fan and the cooling switch. The cold air will disperse the fog on the windshield. 2. Open the windows slightly to allow the exchange of hot and cold air. Crack the side windows to promote air convection inside the car, bringing the interior temperature closer to the outside temperature, which will help the fog dissipate. 3. Use specialized anti-fog products. Spray them evenly on the windshield and wipe clean to form a transparent protective film that prevents fog formation. 4. Mix dishwashing liquid with water and apply it evenly on the glass with a sponge. Once dry, wipe it off with a clean towel. This method leaves no watermarks and can effectively prevent fogging for up to 20 hours.

Whenever I encounter fog on the outside of the front windshield, I simply activate the wipers for a quick swipe, and it usually clears up instantly. If the effect isn't obvious, I immediately turn on the car's air conditioning, select the defogging mode (usually the fan blade icon), and adjust the airflow direction toward the windshield. I avoid setting the temperature too high, as hot air can sometimes make external fog worse. It's recommended to switch the ventilation to external circulation to help reduce the temperature difference between the inside and outside of the car. I also try to keep the windows clean regularly, as dirt buildup can make fog harder to remove. This situation often occurs during summer rains, so it's good to check if the wiper blades are worn out in advance and keep a quick-spray cleaner handy. If fog suddenly thickens while driving on the highway, slowing down gradually and pulling over safely is the best approach. Personally, I find this method straightforward and practical, ensuring driving stability is the key.

Over the years of driving, I've noticed that fogging on the front windshield commonly occurs in humid weather or rainy days. My usual approach is to first use the wipers for a quick clear-up. If the fog persists, I turn on the air conditioning's dehumidification function, setting it to cold air with external circulation directed at the window. It's crucial not to overlook the condition of the wipers; aged or worn-out ones won't clean effectively. During regular car washes, using glass cleaner to wipe the windows proves more effective in preventing fog. For safety, when visibility is poor, slowing down or pulling over is advisable, avoiding sudden acceleration which can cause moisture condensation. Experience has taught me that sudden temperature drops in winter also easily lead to fogging, so pre-warming the car or using a defroster can help. Maintaining the air conditioning system is equally important, with regular checks to ensure the air ducts aren't blocked, guaranteeing smooth airflow. These steps are simple daily practices that don't require major efforts, ensuring both comfort and safety while driving.

Simple ways to deal with fogging on the front windshield: Turn on the wipers and swipe a few times, and the fog will mostly clear. If that doesn't work, turn on the AC and use the defog button to blow cold air toward the windshield. Turn off the recirculation mode and switch to fresh air mode to reduce humidity differences. When washing the car, pay attention to cleaning the glass—less dust means less fogging. Always keep windshield washer fluid handy for emergencies while driving in the rain, and avoid using warm air as it can worsen fogging. Safe driving is the top priority.
