What to Do When Rearview Mirrors and Windows Are Blurred with Water After Rain?

Rain deflectors are easy to install, inexpensive, and effective in light rain without obstructing the view, but they are less effective in heavy rain and may affect the vehicle's appearance. Apply soap to a damp cloth, then wipe the mirror with it. After the mirror dries, gently remove any residue with a tissue.
My car often gets its rearview mirrors and windows completely blurred by rain in wet weather, making visibility dangerously low. I used to struggle with this too, but now I turn on the rearview mirror heating function as soon as I start driving. This feature can be found near the steering wheel—just press it lightly to heat the mirror surface and clear away the rain. Additionally, don’t forget to activate the air conditioner’s defogging mode, setting it to a lower temperature and directing the airflow toward the front windshield and rear window. This quickly disperses condensation. Regularly check your wiper blades, and replace them if they’re worn out, as old ones won’t clean effectively. I also bought a specialized rain-repellent spray online, like Rain-X, which forms a waterproof layer on the mirrors and glass, causing rainwater to slide off without needing to wipe it. When there’s a lot of fog inside the car, avoid using the recirculation mode for too long or crack a window slightly to help with ventilation. Developing a habit of checking your wipers’ condition when parking can prevent similar issues and improve driving safety in the rain.
Driving in the rain with poor visibility due to foggy mirrors and windows is such a headache. I always quickly turn on the defogging system by pressing the button under the windshield to activate the fan blowing cold air. At the same time, I switch on the rearview mirror heating function to evaporate the rainwater. I recommend keeping a bottle of rain-repellent spray handy—clean the mirror surface thoroughly and let it dry completely before applying to form a protective film that reduces water droplet buildup. Windshield wipers are crucial; if they’re aged or the rubber is cracked, they won’t work properly, worsening blurriness. During regular maintenance, ask the technician to check if the wiper pressure is adequate. If fogging is severe, switch the AC to external circulation mode to help dehumidify. I also suggest covering the car with a protective cover when parked to prevent water accumulation. Safety comes first when driving in the rain—take it slow and maintain a safe distance for peace of mind.
