What to do when the rearview mirror is covered with water droplets and visibility is poor on rainy days?

[OBeckett]

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.
