What should I do if the car rearview mirror is wet and I can’t see clearly in the rain? Here are some common treatment methods.
1. Use smearable items
Soap or detergent
You can mix soap or detergent with water, stir it evenly, and then apply it to wipe the rearview mirror lens and dry it. Soap can destroy the surface tension of water, so that water molecules are distributed on the surface of the rearview mirror in the form of a water film. The more rain, the larger the water film, which can maintain better clarity; the surfactant components in detergent will migrate water outward to prevent water droplets from forming. But this method lasts for a short time and will fail in about two days.
Water repellent
After cleaning the rearview mirror, spray the water repellent and wipe it evenly. The main component of the water repellent is silicone oil. By changing the tension of water on the glass surface, the surface of the rearview mirror is kept clean, thereby maintaining a clear field of vision.
Toothpaste
Apply toothpaste evenly on the rearview mirror and then wipe it off. When it encounters water, it can be quickly washed away and will not stick to the rearview mirror glass, which plays a certain role.
Wax
On waxy objects, the cohesive force of water is greater than the adhesive force, and water droplets cannot gather. However, wax is easily affected by the external temperature, and improper operation will affect the line of sight, so it is not recommended.
Two, use the heating function
Many cars are equipped with a rearview mirror heating function. After turning on the switch, the electric heater can quickly heat the temperature to between 35 and 60 degrees, which can quickly evaporate water droplets, eliminate fog, and improve the blurry situation of the rearview mirror.
Three, install accessories
Rearview mirror rain shield (rain eyebrow)
The rain shield is similar to the rearview mirror hat. It is more suitable when the rain is not heavy, and can effectively prevent rain from dripping on the rearview mirror. It can also block the water on the car window to keep the rearview mirror and side glass clear as a whole. But the effect is limited in heavy rain.
