The solution to unclear rearview mirrors in rain is: gently rub soap on the rearview mirror a few times, then wipe it clean with a dry cloth. This can keep the rearview mirror clear for 2 to 3 hours. The rearview mirror is one of the important safety components on a motor vehicle, used to observe the road conditions behind during reversing and to monitor the surroundings while driving. In domestic vehicles, the reflective coating of rearview mirrors is typically made of silver or aluminum, with some using chromium. Currently, in foreign vehicles, chromium mirrors have replaced silver and aluminum mirrors. The interior of the vehicle usually has an anti-glare rearview mirror installed, which consists of a special mirror, two photodiodes, and an electronic controller. The electronic controller receives signals of front and rear light from the photodiodes.
I often encounter the problem of blurry rearview mirrors during rainy days while driving. The most straightforward solution is to immediately pull over and wipe the mirror surface dry with a clean towel, while also checking if the mirror surface has aged or accumulated dirt, making it easier for water droplets to adhere. In the long run, it is advisable to invest in rain-repellent coatings or films, which can be purchased at automotive supply stores and effectively reduce rainwater retention. Additionally, some vehicles come with built-in heating functions that can quickly remove moisture when activated during rain. Remember, safety comes first—always slow down when visibility is poor in rainy conditions, check your surroundings before reversing, and avoid accidents in blind spots. Regular maintenance should also include periodic cleaning of the mirror surfaces to ensure they do not obstruct driving visibility.
As a car enthusiast who loves modifications, I believe the coolest way to solve unclear rearview mirrors in rainy weather is to install professional rain-repellent coatings or attach external wiper devices. There are many high-quality products on the market, such as nano-coatings, which cause rainwater to slide off without leaving traces, costing only a few dozen yuan. Installing wipers requires some skill, but adding a small wiper that automatically cleans is perfect for areas with frequent rainfall. Also, check if the mirror is securely installed, as any looseness can make water stains more likely to accumulate. To prevent fogging, you can wipe the mirror with alcohol to keep it dry, making it easy to handle sudden rain while driving.
