What to Do When Raindrops on the Car Door Window Obscure Visibility?

You can clean it with soap. If fog forms, it can be dangerous while driving. In summer, you can wipe the windshield and rearview mirrors clean. In winter, when morning temperatures are low, you can use a cotton cloth to wipe them clean or turn on the car's heater to blow warm air. You can scrape a little wax from a candle, mix it with alcohol, and then use a towel to wipe it onto the rearview mirror. You can adjust the rearview mirror downward without obstructing your view, making it harder for rain to accumulate and easier for it to flow off. If the rearview mirror has a heating function, you can turn it on.
When there are water droplets on the outside of the car glass on rainy days, making it hard to see, I first check if the windshield wipers are working properly. If the wiper blades are worn or cracked, they should be replaced promptly; otherwise, their effectiveness is greatly reduced. While driving, maintain a moderate speed, avoid sharp turns or rapid acceleration to minimize water splashing and ensure a steadier view. I always pay special attention to cleaning the glass surface during car washes to reduce oil buildup—water droplets tend to cling more where there’s more oil. You can try hydrophobic or anti-fog products available on the market; spraying them makes water droplets roll off faster, and one application before driving can last several days. When driving in the rain, always turn on your headlights and fog lights to increase visibility for yourself and others. Safety is no small matter—don’t wait for an accident to regret it.
