The biggest problem driven in the rainy days is that the sight is blocked.，Window glass and rear view mirror have raindrops，Will greatly affect the driver's sight，Especially in the corners of people or vehicles intersect or transport busy environments，It greatly affects driving safety。
What should I do in this case?？Some people may say that the rear view mirror of our car has heating function.，Can avoid this problem to some extent。but，Even if heated the rear view mirror to evaporate the water on the rearview mirror，But because there is still rain on the side window glass，It still can't see the situation in the rearview mirror from the car.。If you use a method of emitting a glass，Although watermarks on the glass，But the vision becomes clearer，You can basically see the situation in the rearview glass through the glass.。But the durability of this method is not good.，soon，Side window glass's field of view“Restore its original shape。”
In addition，Still a large part of the model，Rear view mirror no heating function，What should we do?？In fact， There is a way。Let us discuss a more“Earth”Methods。Use soap。
Specific use method is：Applying soap on a glass window and rear view mirror，Don't worry about the cleaning, but wait for soap to blow dry by the wind。After the water on the window，Just wiped soap。
You must know that when we go to the glass, you can use it without water. You can find a towel directly wipe it.，If only soap is wiped on the window glass on the driver side，then，We can use a paper towel to wipe the soap。
After we wi clean, we will find，Even if it does not have a great impact on the sight over a period of time，When rains go to the glazing and rear view mirrors，The rain will automatically flow and not form a blurry water column.，People can't see。
It is worth noting that，The durability of this method is not very good.，Usually invalid within a few hours，But for ordinary short drives，Still no problem。
