What to Do When Car Rearview Mirrors Are Blurred by Rainwater?
1 Answers
Solutions for unclear rearview mirrors due to rainwater on rainy days are as follows: 1. Install rain guards, which are suitable for light rain: Rain guards can block water on the windows, keeping the rearview mirrors and side windows clear overall. 2. Use soap or dishwashing liquid: Simply spray soapy water or dishwashing liquid water on the rearview mirrors and let them dry. Cleaning agents contain surfactants, whose hydrophobic groups will push water outward due to physical properties, preventing the formation of water droplets. However, the effect is short-lived, lasting only about two days. 3. Apply water repellent to prevent water from sticking to the rearview mirror surface: Applying water repellent to rearview mirrors helps maintain clear visibility. The main component of glass water repellent is silicone oil, which changes the surface tension of water on the glass to prevent water from sticking to the rearview mirror surface.
