From the results of the experiment above,Not only the perspective effect is still available，The water repellent effect of soap can be comparable to professional rain enemies，The practicality is completely guaranteed。

Except the above "Earth Measures", the owner and friend can alsoCombinationThe following methods are used, and the effect may be better.

1. Use rearview mirror and rear window electricity heating function

Many models have rearview mirror heating function，After opening，When it rains,，The rearview mirror can also maintain a good definition。P.S. If the side window glassstill with rainwater,Even if the rearview mirror is used to heat and steam the water on the rearview mirror，I still can't see the situation in the back mirror from the car，The effect is greatly reduced。

2. Pretend to be rainy eyebrows

The benefits of installing rainbrows，When we encounter light rain or medium rain during the driving process，At this time, the rain eyebrows can play a certain effect，Makes rain water directly on the rearview mirror，But if you encounter heavy rain,，Maybe the effect of rain eyebrows is worse，At this time, we need to reduce the speed of the car appropriately，After all, safety is the most important。

3. When the rain is not heavy, you can open the window appropriately to let the air flow against the flow

If the rainfall is not large，We can also open a gap on the windows on both sides，Make the air inside and outside the car forming a convection，Let the temperature in the car quickly close to the temperature outside the car，No temperature difference，Fog will naturally disperse。This is the most commonly used method to remove windshield fog，If you encounter winter，The temperature is very cold，Unexpectedly when you are unwilling to open the window，You need to use the method of point 4。

4. Open cold and cold wind

Rainy days，General temperature will decrease，At this time, the window glass is relatively easy to get fog。The fog is due to the temperature difference between the two sides of the window，The air humidity in the car。So this situation is general，This problem can be solved through the cold wind and hot air。

Hit the air conditioner to the degradation file，After the compressor is started，can have a good use of dehumidification function，The air humidity in the car decreases，The mist on the window will naturally disappear。The same hot wind can also be fog，But the time for divorce is slightly longer than the cold wind，and when the air -conditioning hot air just turned on，Because the temperature difference inside and outside the window becomes larger，Fog will become greater，But wait a while to fog to disappear slowly。

Last，Xiaobian reminds you，Drive on rainy days，Wet on the road，Be sure to keep a safe speed，Careful driving。(Photo derives from the Internet，If you seabet logininvolve the copyright, please contact delete)
