When we drive on a rainy day, we often encounter the situation where the rearview mirror cannot be clearly seen. It is raining outside the car, and it is inconvenient to open the window and clean the rearview mirror. However, the rearview mirror is covered with a layer of mist and cannot be clearly seen, which is very disturbing. Drive safely. So what should you do if the rearview mirror cannot be seen clearly due to rain? Here are some tips for you:
1. The easiest way is to use soap or dishwashing liquid to spray the rearview mirror and then wipe it dry. Because soap can destroy the surface tension of water, causing water molecules to be evenly distributed on the surface of the treated rearview mirror in the form of a water film. The more rain there is, the larger the water film will be, and the glass of the rearview mirror will always remain clear. Spend. The most important component of dishwashing liquid is surfactant, which will move water outward, making the rearview mirror less likely to fog up. The disadvantage of the above method is that it will lose effectiveness in about two days.
2. Wax the rearview mirror to prevent fogging. When water is on a wax substance, the internal cohesion of the water is greater than the adhesion force, so water droplets cannot accumulate. However, this method is not recommended. Improper operation will affect the line of sight.
3. Install rain eyebrows. The effect is not good in heavy rainy weather, but it is suitable in light rainy weather, and it is cheap and practical.
4. Evenly applying toothpaste on the rearview mirror can also play a role. Wipe it off after applying it. It can be quickly washed away when exposed to water and will not stick to the rearview mirror glass.
25. Water repellent removes moisture. Before spraying, clean the glass and cleanly. After spraying the water repellent, wipe it evenly. It is similar to waxing, and the effect is indeed better.
6. Some models have a rearview mirror heating function, which can also eliminate water mist in rainy days.
