Cleaning all parts of the car is an important part of car beauty and the basis for subsequent beauty. From a basic theoretical point of view, washing a car with detergent is a complex process of interaction between chemical and physical phenomena. If the cleaning and maintenance are not done properly, it may lead to "good intentions leading to bad consequences" - not only does it not extend the life of the car, but it will also "damage" the car.

　　Choose professional cleaning agent

　　Currently, there are general alkaline cleaning agents containing active ingredients on the market, such as washing powder, soap, detergent, etc. They have a certain decontamination ability when used to wash cars, but further analysis reveals problems. Professional car beauty should prohibit the use of alkaline cleaning agents to clean the car paint surface. Strictly speaking, cleaning agents containing anionic surfactants should be used to clean the car paint surface to achieve the purpose of removing static electricity, cleaning oil stains and maintenance of the car body at the same time. The cleaning of other parts of the car follows the same principle. Different professional cleaning agents must be used for parts made of materials with different properties. These cleaning agents are manufactured according to the requirements of modern automobile technology, according to unique formulas and production processes, and are special cleaning agents that cannot be replaced by general civilian cleaning.

　　Master the correct cleaning method

　　It is not enough to realize that different parts of the car must be cleaned with different cleaning agents. It is also necessary to further understand the use of each cleaning agent. If you do not master the correct cleaning method, you will not be able to achieve the desired effect. For example, when cleaning the oil on the surface of the engine, you should choose a weak alkaline cleaning agent containing a cationic surfactant with good biodegradability. After spraying, it should stay on the surface of the machine for 2-3 minutes, and then rinse with water after the surfactant has completed the process of wetting, emulsifying, increasing the volume, and dispersing the dirt. If rinsed too early, the oil cannot be rinsed off and the cleaning effect cannot be achieved. The cleaning agent with biodegradability will not pollute the environment after discharge.

　　Here we also remind you to pay attention to the cleaning of the circuit and electrical parts of the engine when washing the engine. Modern luxury cars mostly use electronic injection fuel supply systems and other electronic control components, and the electronic components in these parts have high requirements for cleaning agents. If water-based cleaning agents are used for both the mechanical and electrical parts of the engine without distinction, the electronic components of the electrical parts may be damaged, making the engine unable to work normally. At this time, it is necessary to use volatile electronic equipment special cleaning agents, or use electronic component cleaning agents with insulation to clean the electronic parts. People engaged in car beauty who do not pay attention to strictly control the quality of cleaning agents are equivalent to providing users with poor quality services.
