It's not that easy to wash your own car. Pay attention to these places when washing the car.

Now that the weather is getting hotter and hotter, many car owners will choose to wash their own cars. First, it is more comfortable to wash the car by yourself, because the weather is hot and the water is not so cold. Secondly, because there is enough rain in summer, you can wash your dirty car at any time, so you don't have to queue up at the car wash, saving time. Finally, you can save a little money.

After the car is dirty, many people will think of washing it with water or wiping it with water, and some people will add detergent to the water to wash the car. These practices are not necessarily appropriate. Washing with water can only wash away common dirt such as dirt and dust, and has little effect on other dirt, and many parts of the car are not waterproof at all, so washing with water is easy to hurt the car. Washing the car is not that simple. If you don't wash it properly, you may even hurt your car! Friends who want to wash their own cars remember these points:

The first part of a car that can't be washed is the engine compartment.

Don't think that when washing a car in a car wash, you usually see some car washers washing with water guns, and you can do it yourself. This is a big misunderstanding. There are many parts in the engine compartment that can't get wet, and the car washer is experienced. They know which cars have waterproof design and how to wash them so as not to accumulate water. If the owner directly washes with water, all kinds of electronic components, fuse boxes, circuits, etc. If they are washed directly with water, it is easy to cause short circuit, accelerate the aging of engine parts and even directly lead to damage. Moreover, a lot of dirt on the engine can not be cleaned directly by washing with water. It may also lead to engine scrapping.

Second, the exhaust pipe

Because the exhaust pipe is located at the bottom of the vehicle and relatively low from the ground, it is easy to enter the muddy water on the road, and because the exhaust gas of the vehicle is also discharged from here, the interior of the exhaust pipe will darken when we touch it with our hands, which should be regarded as the dirtiest part of the vehicle. But no matter how dirty the exhaust pipe is, it can't be washed with water, because there is a carrier catalyst and oxygen sensor nut in the exhaust pipe, and there is a filter element in the exhaust pipe. After washing with water, the filtration effect will be affected, resulting in increased emissions and carbon deposition. The accumulated water in the exhaust pipe will also corrode the exhaust pipe, and the exhaust pipe cannot be cleaned well. For the mud on the exhaust pipe, it can be cleaned directly with small tools, and the carbon deposited inside can be used with a three-way catalyst.

Three-way catalyst catalyzes nitrogen oxides, carbon monoxide, hydrocarbons and so on. Harmless carbon dioxide, nitrogen and water existing in the tail gas also have the function of removing carbon deposits inside the engine. Three-way catalyst is easy to be blocked when used in automobiles for a long time. Three-way catalyst can remove the above blockage and play a good role in cleaning and protecting.

Three, electrical components socket

Some car owners wash their cars carefully, and all aspects of their cars should be cleaned. However, there are many sockets in the car, and the location is relatively hidden. Some have waterproof rubber layers, while others have nothing. If the owner sticks water on the plug-in interface when cleaning, it is like splashing water on the plug-in board, and the consequences can be imagined.

Fourth, car headlights.

Car headlights is also not suitable for direct washing with water, because the washing process will cause water to enter the interior of headlights, and a large amount of water mist will be formed in the future, which will affect the lighting. Moreover, the headlights are dirty, mostly because of wear and tear, and washing with water has no effect at all. If you want to make the headlights smooth and bright again, you can use professional headlight cleaning tools. First, use sandpaper to polish the headlights, and then use headlight cleaning agent to spray the headlights, which can repair the dirty scratches on the headlights and make the headlights brighter.

In fact, there is nothing wrong with washing your own car, but you should pay attention when washing your car. If the owner doesn't know anything about the car, just wipe the surface of the car, and then wipe other places after you are thoroughly familiar with the car.
