What to Do When the Rearview Mirror Is Blurred by Rain?

Here are specific methods to address blurred rearview mirrors due to rain: 1. Install Rain Guards: However, rain guards have certain limitations. They typically come in two types: external and internal installation. External ones are directly adhered to the rearview mirror, while internal ones are inserted into the gap between the rearview mirror and its frame. Internal rain guards need to consider thickness issues, which may affect the adjustment of the rearview mirror itself. When selecting rain guards, pay attention to the hardness of the plastic material for easier shaping. 2. Apply Water Repellent: This changes the surface tension of water on the glass, preventing water from adhering to the rearview mirror surface. After applying water repellent, raindrops on the glass can be easily shaken off or blown away by wind. 3. Rearview Mirror Heating: Through heating elements embedded behind the mirror, the mirror's temperature rises above 40°C, accelerating the evaporation of moisture on the surface.

I've encountered several situations where the rearview mirror was covered by rain and hard to see, especially when driving in heavy rain, which is particularly troublesome. A simple method is to use a clean, soft cloth, such as a microfiber cloth, to gently wipe the surface of the rearview mirror when stopped at a red light or safely pulled over. This can immediately restore clear visibility. Remember to turn on the hazard warning lights before stopping to ensure other vehicles notice you and avoid accidents. Additionally, you can keep a special rain-repellent spray in the car and apply it after each wash to form a protective layer that reduces rainwater adhesion. Prevention is always better than emergency measures—check the rearview mirror before it rains to ensure it's clean and free of stains. Maintaining driving safety is key. If wiping is inconvenient, opening the window and lightly tapping with the wiper's auxiliary arm is a temporary option, but you must stay focused.
