How to Deal with Fogging on the Outside of Side Windows on Rainy Days?

Open the window slightly to let in cold air. Wipe away the fog with a cloth. First turn on the air conditioning to cool, wait for the fog to disperse, then switch to heating, and adjust the air vents to blow towards the windshield. Wiping the inside of the windshield with a cloth dipped in dish soap or a special anti-fog agent can effectively prevent fogging.
I've encountered fogging on the outside of car windows on rainy days many times. It's mainly caused by excessive rainwater and temperature changes leading to condensation on the outer surface of the glass. My solution is to first quickly activate the windshield wipers, which usually clears the fog temporarily. If that doesn't work, I turn on the air conditioning, adjust the vents to direct air towards the windshield and side windows, and switch to external circulation mode to help balance the temperature and reduce condensation. Avoid setting the cabin temperature too high or using internal circulation for too long, as increased humidity makes fogging more likely. Regularly check the wiper blades for wear and replace them if they're old. Some people apply soapy water or specialized anti-fog products to the glass to minimize fog formation. In short, delayed treatment can obscure vision and affect driving safety, so it's advisable to clean your car windows in advance whenever it rains to maintain clarity.
To deal with fogging on the outside of side windows, don't panic. Let's talk from a practical perspective. First, check if the wipers are working properly. If they aren't wiping effectively, replace the wiper blades or add glass cleaner. The air conditioning system is crucial: set the fan speed to maximum, adjust the temperature to a moderate level (neither too hot nor too cold), direct the airflow toward the windows, and turn on the A/C button for dehumidification—this can quickly remove fog. Another handy trick is to wipe the glass surface with a clean cloth to prevent dirt buildup, which can absorb moisture. For long-term prevention, regularly maintain the cabin air filter and glass, and applying an anti-fog coating works well. Remember, fogging is no small matter—poor visibility while driving is dangerous, so address it promptly for peace of mind. If the issue persists, it's best to have a professional inspect the electrical system or wiper mechanism for faults.
