What to Do When Car Windows Are Invisible on Rainy Days?
2 Answers
Here are solutions for when car windows are invisible on rainy days: 1. When driving in the rain, fear of blurred rearview mirrors affecting visibility. If the blur is caused by fogging on the side windows due to temperature differences between inside and outside, adjusting the air conditioning temperature and direction for the driver and passenger seats can solve the issue. If the problem is external rainwater, some measures are needed. 2. On rainy days, evenly apply toothpaste or soap to the car's side windows, wait for the applied soap to harden, then wipe it off with a towel. This will form a wax layer on the glass surface, which has excellent water-repellent properties, effectively preventing fogging or water droplets on the rearview mirrors that cause blurred vision. Additionally, keeping soap in the car can also freshen the air and eliminate odors. 3. Purchase and use specialized water repellents. Water repellents on the market generally come in two forms: spray and wipe-on. Evenly spray or apply the water repellent to the rearview mirrors, and a protective film will form on the surface. This film also has excellent hydrophobic properties, effectively preventing fogging or water droplets on the rearview mirrors, ensuring clear visibility.
When driving in the rain, if the windshield becomes blurry, I pay special attention to the condition of the wipers. If they don’t wipe cleanly or leave water streaks, it’s likely that the wiper blades have aged, and it’s best to replace them with a new set immediately—don’t delay to save a little money. If there’s an oily film or stains on the glass, you can use a dedicated cleaner or simply treat it with white vinegar to keep the surface smooth, which helps rainwater slide off. During the drive, set the air conditioning to defog mode and direct the fan toward the windshield with cold or warm air to quickly disperse moisture. More importantly, maintain safety awareness—when visibility is poor, don’t rush. Slow down, turn on the hazard lights, and ideally, find a safe place to stop and wait for the rain to ease. For regular car maintenance, check the wiper blades and windshield every few months and spend a few minutes cleaning them to avoid these hassles.
