How to Solve Fogging on Side Windows in Rainy Days?
4 Answers
In rainy days, fogging on side windows can be addressed using toothpaste, water repellent, or air conditioning defogging. Specific solutions for fogging are as follows: On rainy days, evenly apply toothpaste or soap on the car's side window glass and wait for a while until the applied soap hardens. Then, wipe it clean with a towel. A wax layer will form on the glass surface, which has excellent water-repellent properties, effectively preventing fogging or water droplets on the rearview mirror that may cause blurred vision. Purchase a specialized water repellent and evenly spray or apply it on the rearview mirror. A protective film will form on the rearview mirror surface, which also has excellent hydrophobic properties, effectively preventing fogging or water droplets on the rearview mirror, ensuring clear visibility. Turn on the car's air conditioning to cold air and adjust the air outlet to the front windshield to quickly clear fogging on the glass. If you want to completely eliminate fogging, you can turn on the air conditioning to hot air before starting the car and blow it directly on the front windshield for 3 minutes. This can fundamentally prevent glass fogging. Air conditioning cooling can also dehumidify and achieve the fastest defogging effect. The driver can turn on the air conditioning's cooling mode and adjust the blowing mode to the windshield position. In about ten seconds, the fog can disappear.
I've been driving for 30 years and encountered foggy side windows on rainy days countless times. The simplest solution is to use the defogger button on the AC, switch to cold or warm air mode, and direct the airflow to blow on the side windows for a few minutes - the fog will clear quickly. Opening the window slightly also helps by improving air circulation and preventing moisture buildup inside. Keep a clean microfiber cloth in the car to occasionally wipe the windows inside and out; less dirt means less frequent fogging. Applying anti-fog spray on the inner glass surface works well too, available at any supermarket. If visibility becomes severely impaired, don't hesitate to pull over safely to address it. Safety first - remember to regularly check your AC system to ensure the dehumidification function works properly. These small habits give me peace of mind while driving, ensuring clear visibility even in rainy conditions.
Fogging on the side windows during rainy days is a normal phenomenon caused by temperature differences leading to water vapor condensation. The interior of the car is warm, while the rain outside cools the glass. The solution is to activate the air conditioning's dehumidification function, which reduces interior humidity and accelerates fog dissipation. Using the external air circulation for ventilation aids air exchange and is more effective than recirculating interior air. Adjust the air vents to direct airflow toward the side windows, and the fog should clear within minutes. Alternatively, slightly opening a window can introduce drier air. Keeping the glass clean is crucial, as oily residues attract moisture and make fogging worse. Don’t forget to use interior dehumidifiers to absorb excess moisture. Understanding this principle allows you to address the issue effectively: avoid blasting hot air when temperature differences are significant and keep the air filter clean. Drive safely in the rain—clear visibility is essential.
When traveling with kids in the car, I worry most about side windows fogging up on rainy days. Simply turn on the AC defogger function and increase the fan speed. No AC? Crack open a window slightly to let fresh air in. Gently wipe the inside of the glass with a cloth to remove condensation. I keep defogging wipes in my car—they're convenient and effective. Avoid leaving wet clothes or umbrellas in the car, as they increase humidity. Using the AC in fresh air mode is better than recirculating stale air. If fogging is heavy, slow down and wait for it to clear before speeding up. These simple tips are easy to learn and ensure family safety on the road. Make sure wipers work properly and keep the exterior glass clean. Teach these to your kids once, and driving in the rain won’t be stressful.
