What to Do When the Rearview Mirror is Unclear on Rainy Days?
1 Answers
Here are methods to make the rearview mirror visible on rainy days: 1. Clean with soapy water. Soap disrupts the surface tension of water. When soap is introduced into water, water droplets do not stay on the object. Applying soap to the rearview mirror works similarly; when rain falls on the mirror, the droplets will slide off on their own. 2. Install rain guards on the rearview mirror. On rainy days, cars equipped with rain guards do not need to worry about water droplets obscuring the view of the road behind. 3. Apply a waterproof film. The principle of this method is similar to using soapy water, but the waterproof film is more durable and long-lasting. While soap is a one-time solution, the waterproof film can be used continuously.
