What to Do When Car Windows Are Invisible on Rainy Days?
4 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.
As a driver who loves trying new things, I've found that during rainy days when the windshield gets blurry, the effectiveness of wipers often depends on maintenance frequency. I make it a habit to inspect the wiper blades every six months, checking for cracks or hardening, and replace any damaged ones to prevent scratching the glass. Here's a handy tip: apply a glass water repellent—just buy a spray bottle online, apply it, and rainwater will bead up and roll off, giving you clearer visibility. Turning on the air conditioning beforehand to defog the windshield is also effective; set the fan to medium and direct it toward the glass to save power and stay safe. If visibility suddenly drops to zero while driving, don’t panic—lightly tap the brakes, slow down, pull over, and turn on the hazard lights for a while. Remember, avoid forcing high-speed driving as accident risks skyrocket. When cleaning the glass, use a neutral detergent and avoid scrubbing with hard objects to prevent scratches.
During heavy rain, my top priority is ensuring the defogging function of the air conditioning works properly—turning on the fan to blow air towards the windshield quickly clears condensation. The windshield wipers are my main tool; if they're broken, they need to be replaced promptly to avoid impairing visibility. Keeping the glass clean is equally important. If the surface is greasy, just use some automotive glass cleaner to wipe it down. For safety, I always remind myself: slow down when visibility is poor, turn on the hazard lights as a warning, and if necessary, pull over to a safe spot and wait for the rain to stop. For regular maintenance, I recommend checking the wiper blades quarterly to prevent aging issues from becoming bigger problems.
