There are several measures to remove small water droplets from the rearview mirror on rainy days when visibility is poor. Here are the specific measures: Using the rearview mirror heating function to remove water droplets: Use the car's rearview mirror heating function, but this method has certain limitations. The heating process is slow, and the switch only works on the rearview mirror; the side windows cannot be heated. In heavy rain, the effect is minimal. Installing rain guards to reduce water droplets: Rain guards, also known as "rearview mirror rain visors," are made of resin material and can be bent as needed. They are attached to the rearview mirror with special double-sided tape, functioning like a small umbrella over the rearview mirror. Installed rain guards are quite effective when the rain is not too heavy. However, in heavy rain, their effectiveness diminishes, especially for rain falling at an angle, where the effect is even poorer.
When there are too many water droplets on the rearview mirror on rainy days and it's hard to see, I first turn on the air conditioner to the hottest setting and blow it at the rearview mirror for a few minutes. The hot air helps evaporate the droplets quickly, which works quite fast. Keeping a water-repellent spray in the car is also very practical—spraying it on the mirror causes water to bead up and slide off, reducing water buildup. Remember to clean the mirrors during regular car washes to prevent oil and dirt buildup, which can worsen the problem. Safety comes first when driving; if visibility is poor, don’t rush to reverse. Drive slowly or pull over and wait for the rain to ease up. Once during heavy rain, I almost hit a pedestrian, and since then, I’ve made it a habit to check the mirrors before driving. Combining the air conditioner and spray, along with regular maintenance, has significantly reduced such issues, making rainy-day driving much more reassuring.
When the rearview mirror has water droplets and visibility is poor, I particularly like using professional water repellents, such as those with nano-coating. After spraying, they form a protective film that causes water droplets to roll off directly, providing long-lasting effects. Turning the car's air conditioning to maximum speed and directing it toward the rearview mirror helps with dehumidification, as the hot air has strong drying power. Installing rain guards can block raindrops and reduce water adhesion, which is quite convenient. I've tried several products, and rain repellents work the best. For daily maintenance, avoid using rough cloths to clean the mirror; instead, use a soft cloth to gently wipe it to prevent scratches. For safe driving, it's advisable to enable the rearview camera for assistance and slow down gradually. Poor visibility on rainy days increases the risk of accidents. Combining these small tips helps maintain clear vision and makes driving more reassuring.
