What to Do When Car Rearview Mirrors Are Unclear in the Rain?

Installing rain deflectors is like putting up an umbrella for the rearview mirrors. They work perfectly for light rain, though they are less effective in heavy rain. Still, they are much better than having nothing installed. Applying soapy water to the rearview mirrors can keep them clear for 2-3 hours even in heavy rain. Shampoo and similar products have a similar effect. The main component of insect repellent is silicone oil, which causes rainwater to slide off. Spraying a little on the rearview mirrors during rain can help prevent water buildup. Heated rearview mirrors evaporate the water. Many cars now come with rearview mirror heating features—simply turn it on when it rains.
When driving in rainy weather, I often encounter the problem of blurry rearview mirrors, but the solution is actually quite simple. First, after parking, use a clean soft cloth to dry the mirror surface, removing water droplets and dirt. Second, apply some waterproof spray like Rain-X on the mirror, which helps rainwater slide off quickly without sticking. I also check if the rearview mirror's heating function is turned on, as it works even better if available. Additionally, while driving, increasing the wiper speed and using the rear wiper can improve visibility. Regular cleaning of the mirrors is crucial—don’t overlook this detail during car washes, as dirt can worsen water accumulation. For safety, when visibility is poor, I slow down below the speed limit, avoid sudden lane changes or overtaking, and rely more on the side windows to observe surrounding traffic conditions.
