What to Do When Rearview Mirrors Are Unclear in the Rain?

[AnnieLynn]

Solutions for unclear rearview mirrors on rainy days are as follows: 1. Rearview Mirror Heating Function: Many modern cars are equipped with a rearview mirror heating function, which uses embedded heating wires behind the mirror to raise the surface temperature, accelerating water vapor evaporation. 2. Install Rain Guards: Not all cars have heated rearview mirrors. For vehicles without this feature, installing rain guards is an option. These can keep the mirror clear in light rain and ensure at least one-third visibility in heavy rain. 3. Apply Water Repellent: The main component of water repellent is silicone oil, which alters the surface tension of the glass, making the rearview mirror water-resistant. After application, rainwater forms round droplets that can be easily shaken or blown off. However, reapplication is needed every few months. 4. Use Laundry Detergent or Soap: Apply a clean, wet cloth or sprinkle laundry detergent, then spread it evenly on the rearview mirror. Wait a few minutes for it to dry, then wipe clean with a tissue. This method is not suitable for long-term use but is convenient and low-cost.
