How to Remove Fog from the Windshield on Rainy Days
3 Answers
When the windshield fogs up on rainy days, the following methods can be used to remove the fog: Turn on the defroster in the car: Activate the defroster while also pressing the compressor (A/C) button. This will lower the temperature inside the car, which may feel cold in autumn and winter, but the defogging effect is noticeable. Turn on the warm air from the air conditioner: Increase the fan speed. The dry, warm air will evaporate the moisture inside the car, preventing fog from forming on the windshield. Purchase dry anti-fog wipes: Before using dry anti-fog wipes, first wipe the windshield with a damp cloth or use them directly when fog appears. After wiping, the windshield will remain fog-free for up to 24 hours. Purchase wet anti-fog wipes: Wipe the fogged areas directly. After wiping, the windshield will remain fog-free for up to 24 hours. Purchase anti-fog spray: Spray the glass anti-fog agent directly onto the windshield. The anti-fog effect typically lasts around 10 days, with high-quality products even lasting up to a month, far outperforming anti-fog wipes.
The most annoying thing when driving in the rain is the fogging on the windshield. I've figured out a simple and effective method: don’t rush to turn on the AC when you get in the car. First, turn on the external circulation to balance the temperature inside and outside the car. Then, press the AC button, lower the temperature slightly, and turn on the windshield defogger. Here’s the key—increase the fan speed to blow air onto the windshield, and the fog will clear up quickly. Avoid just using the heater or relying solely on the wipers, as that will only make it worse. Also, keeping a dry towel handy to wipe the inside of the glass is quite convenient, but don’t get distracted while driving. For long-term maintenance, regularly replacing the cabin air filter can reduce the chances of fogging.
Bro, let me teach you a budget trick! I mix dish soap with water at a 1:10 ratio to wipe the inside of the glass. Once dry, it forms an anti-fog film, costing less than two bucks. But for emergencies, rely on the AC: first press the defog button with a fan and arrow (usually on the left side of the dashboard), immediately turn on the AC for cooling, and remember to switch to external circulation! A detail many overlook—if fog condenses into water droplets, adjust the temperature to about 5 degrees higher than outside for it to work. Also, don’t forget to turn on the rearview mirror heating button. For foggy side rear windows, press the square button with waves. If there are many people in the car, crack the window a bit for faster air exchange.
