How to Deal with Rainwater on Car Rearview Mirrors on Rainy Days?
2 Answers
Generally, cars can only use a towel or similar to wipe it off. For cars with a heating function, when the rearview mirror is heated, the heater behind the mirror quickly heats the mirror surface, gradually removing rainwater or fog from the mirror.
I've been driving for twenty years, and water accumulation on rearview mirrors during rainy days is a common issue. Dealing with it requires practical approaches. A simple method is to spray a water-repellent spray on the mirror surface—water droplets will slide off quickly without leaving residue. Just wipe it clean after spraying; I always keep a bottle in my car. If your car has a rearview mirror heating function, activating it will automatically evaporate the moisture, which is hassle-free. Without this feature, installing rain deflectors is the most effective way to block rainwater—it's easy to install and doesn't cost much. During regular car maintenance, remember to clean the mirrors with professional glass cleaner to prevent oil buildup, which makes water removal harder. Before driving in the rain, check that the mirrors are clean. When reversing, slow down and take extra time to check the sides. Relying on the rearview camera can help you see clearly behind you. Safety comes first—don't take risks. Developing these habits can significantly reduce accidents.
