Why do the rear view mirrors of cars get wet when it rains

First, because the direction of the raindrops is not always the same, coupled with the splashing of water droplets, it is difficult to make the rearview mirror completely free of water. You can try to stick a rearview mirror rain eyebrows yourself, which can play a certain role, or spray water repellent on the rearview mirror, which also has some effect.

Second, the treatment method:

With a coated detergent, the advantages: convenient, cost-effective, and the effect is good.

Applying detergent, soap, shampoo and wax to your car's mirrors is a simple way to temporarily fix the problem of foggy mirrors. When driving in the rain, he applied a layer of detergent to the rearview mirror, and the effect was not bad, especially in heavy rain, which could keep the mirror clear within 1-2 hours. Other friends have also tried to apply soapy water, shampoo, etc., as well as wax the rearview mirror, etc., which can be kept for a longer time.

A few of us just developed this product, a potion, through process operation, painted on the car mirror and glass, the mirror can not be stained with rain, and in heavy rain without wipers does not affect the line of sight at all, (it can be said that a drop of rain will not stick to the mirror and glass) on the mirror and car glass has no corrosion, should be launched into the market as soon as possible.

It's because the lenses are rough and not smooth, so they will get wet when it rains, so try throwing the light.

You can change to a lens that doesn't stick to water.

Because it is not an electrically heated mirror.

Car rearview mirror can be installed if you can't see clearly in the rain, you can use soap to clean the rearview mirror before it rains, and cars with rearview mirror heating can use rearview mirror heating to eliminate rain fog on the rearview mirror. The function of installing rain eyebrows in the rearview mirror is to prevent rain from staying on the rearview mirror in the process of driving the car, and the installation of rain eyebrows is equivalent to holding up an umbrella for the rearview mirror. ”

If you can't see clearly in the car rearview mirror on a rainy day, you can take the following methods, you might as well try it:

1. Modify the ordinary reversing mirror into an electrically heated reversing mirror, when there is water mist on the reversing mirror, the current can be controlled by the switch, and the electric heating wire of the reversing mirror is energized, and the water mist evaporates and melts away;

2. Change the glass of the ordinary triangular window on the door frame to electric heating, and also control the current through the switch to evaporate or melt the water mist on the triangular window glass.

The car rearview mirror will be blurry and can't see clearly when it rains, this should be your car does not have the rearview mirror heating function, you can buy a sticker on the Internet, and it will be somewhat improved by sticking it on it You can also wipe it with soap It can also be improved.

What should I do if I can't see clearly in the rain in the rearview mirror of the car, often rub it, or apply some soapy water, and open the window when reversing.

No, because the rearview mirror is fixed with a screw behind the door, it will not pass through the screw hole to the inside of the door after it is broken, so it will not cause water leakage, and it can be replaced in time, and the broken rearview mirror will affect driving safety. Of course, different cars have different ways of fixing their mirror housings, depending on the actual situation. Remove the mirror surface.

Cover the mirror with the palm of your hand and press the top edge upwards so that the bottom edge reveals a larger opening. Use a tool such as a crowbar to slowly go behind the mirror and tilt it upwards with the palm of your hand. Lasanjo.

Extended information: The use of car rearview mirrors is described as follows:

The rearview mirror is the most prominent part of the whole car, and daily scratching and collision are inevitable. Usually the rearview mirror is just a plastic shell that is broken, and the mirror and the control mechanism inside are not broken, so you only need to replace the plastic shell. Although plastic shells can also be repaired by plastic welding, it is difficult to ensure that there are no traces of repair.

In fact, it is only a matter of dozens of dollars to change the shell.

When dismantling, the mirror surface is more difficult to remove. The main reason is that people who dismantle it for the first time are afraid of dismantling the mirror and dare not use force, such as the above method to cover the mirror with the palm of the hand.

The rearview mirror can be used to observe the situation on both sides of the rear of the vehicle when people are reversing or changing lanes, which can be said to be a very important component. However, on rainy days, the rearview mirror is prone to rain adhesion, which obstructs the view and affects the driving. There are many ways to keep the rearview mirror from rain, so let's take a look.

The best way to remove water from the rearview mirror 1, the soap is more practical is to put a piece of soap in the car, before traveling in rainy days, the soap is evenly smeared on the rearview mirror of the car, after the soap hardens, wipe off with a towel, the glass surface will form a layer of wax, with good water repellency, which can effectively prevent the blurred vision caused by fogging and water droplets in the rearview mirror, and can also increase the fragrance and taste. 2. The use of toothpaste and toothpaste is the same as soap, evenly apply the toothpaste to the rearview mirror of the car, wipe and rinse with a towel, which can effectively prevent the fogging of the rearview mirror. 3. The waterproofing agent is purchased and used with a special waterproofing agent, and the waterproofing agent on the market is generally divided into two types: spray and smear, the waterproofing agent will be evenly sprayed or smeared on the rearview mirror, and a protective film will be formed on the surface of the rearview mirror, which also has good hydrophobicity, which can effectively prevent the rearview mirror from fogging or hanging water beads, and ensure that the rearview mirror is clear.

4. Rain shield and electric heating are installed on the rearview mirror, which can block the rain and prevent the rain from falling and hanging on the mirror surface of the rearview mirror. However, the rain shield can not solve the problem of fogging the rearview mirror, you can add electric heating to the rearview mirror, and the heating wire can increase the temperature of the mirror surface of the rearview mirror, effectively preventing fogging, and the two cooperate with the rain and anti-fogging. 5. The waterproof membrane is attached to the rearview mirror, and the waterproof membrane of the rearview mirror has good hydrophobicity, which can effectively prevent rainwater from adhesion and avoid rainwater blocking the rearview vision, thereby improving the safety factor of driving in rainy days.

A good quality film has high definition, and it also has the functions of waterproof, anti-fog, dust-proof, anti-scratch, anti-fingerprint, etc., which can keep the mirror clear at all times, so as to relieve the trouble of driving in rainy days.

One of the easiest ways to keep the mirrors safe from rainwater is to apply a waterproof membrane to the mirrors. Because the lens surface is coated with multiple layers of anti-reflective coating, the lens is particularly susceptible to stains, which can destroy the anti-reflective effect of the anti-reflective coating. Under the microscope, we can see that the anti-reflective coating has a porous structure, so oil stains are particularly susceptible to infiltration into the anti-reflective coating.

But there are other ways:1Turn on the rearview mirror heating function.

Now most cars have this function, which can evaporate the water vapor on the mirror by heating. Please refer to the manual for the specific opening button. 2.

Installing rain eyebrows, which is available on a certain treasure, is relatively cheap and can play a certain role in retaining rainwater.

3.Soapy water, apply soapy water to the entire rearview mirror, rain will break the surface tension of the stove when it hits the soapy water, and water droplets will not remain on the rearview mirror. However, this one has a disadvantage, that is, it can only last for 1-2 hours.

4.Garlic. That's right, you read that right, garlic can also be noisy.

Crush the garlic and spread the juice evenly in the rearview mirror for 3-5 hours longer than soapy water. When the surface of the extended lens is plated with multiple layers of anti-reflective coating, the lens is particularly prone to stains, which can damage the anti-reflective effect of the anti-reflective coating. Under the microscope, we can see that the anti-reflective coating has a porous structure, so oil stains are particularly susceptible to infiltration into the anti-reflective coating.

The solution is to coat the anti-reflective coating layer with a top film with anti-oil and water-resistant properties, which is the so-called waterproof membrane. And this film must be very thin so that it does not alter the optical properties of the anti-reflective coating. At the same time, it does not allow rainwater to condense on the mirror.

The reversing mirror can be used to observe the real-time road conditions and its driver to observe the whole body condition of the car in the process of driving the car safely, which can be said to be a very important safety component. As everyone knows, on a rainy day, it is very easy for the reversing mirror to be adhered to by precipitation, which then blocks the vision and endangers safe driving. In order to better improve the safety factor of driving in rainy days, how to keep the reversing mirror from raining in rainy days?

1. Apply whitening toothpaste.

Many people will ask whether whitening toothpaste in the rearview mirror can really be waterproof and rainproof, and it can naturally be waterproof and rainproof! Because the whitening toothpaste is applied to the mirror surface of the rearview mirror, it can destroy the tension of the water, when the water hits the mirror, it can produce a certain amount of shrinkage, which can maintain the picture quality of the mirror surface of the rearview mirror, and can effectively avoid the problem of fogging in the rearview mirror, but the time period of effort is the same as that of soap, which can only be maintained for about 2-3 hours;

2. Water repellent agent.

The main ingredient of the water repellent is methyl silicone oil, which can change the support force of water on the laminated glass surface so that the surface of the rearview mirror does not touch the water. The water repellent can be used not only on the rearview mirror, but also on the side laminated glass, which is a low-cost and powerful method. However, at present, the price and quality of water displacement agents sold on the market are uneven, and the key to the car is carefully selected; Waiting.

3. Soap. Before the rainy day traffic, the brigade is instructed to evenly rub the soap on the reversing mirror of the vehicle, and after the soap is dry, wipe it off with a cotton towel, and the surface will produce a layer of wax, which has good water solubility, but this method persists for a short time, and the soap can only be kept for about 2-3 hours before it will be eroded by precipitation;

4. Waterproof membrane.

It can be used to paste a waterproof membrane on the reversing mirror, which has good hydrophobicity and can effectively avoid precipitation sticking to the balance bench. In addition to moisture-proof, the first-class film also has the functions of anti-fog mirror, anti-fouling, anti-fingerprint recognition, etc., which can reasonably maintain the clear surface of the mirror;

5. Electric heater.

Nowadays, many top vehicles are equipped with electric rearview mirror heating effect, and the electric heating pipe can make the mirror surface of the reversing mirror rise, and then accelerate the volatilization of mirror water vapor, reasonably avoid fogging and the like.

Frequently asked questions about driving on rainy days.

Regularly maintain whether the drainage pipe of the moisture-proof groove at the front windshield can be smooth. Prevent water from entering the engine due to water storage in the rain, and prevent short-circuit failure of the driving computer.

Regularly maintain the wear and tear of the brake disc and ensure that it is replaced immediately. If the brake disc is seriously worn, it is easy to shrink between the tread and the sea surface, resulting in deviation, drift and prolonged braking deceleration.
