Due to people's lack of understanding of the role of parts cleaning, the parts cannot be thoroughly cleaned, which affects the assembly quality. Therefore, parts cleaning should attract the attention of drivers.

In the maintenance and repair of automobiles, the cleaning of parts is a relatively important work. When each assembly is disassembled into parts, it is necessary to remove oil, carbon and scale from the parts, so that the assembly and vehicle assembly can be carried out smoothly. By removing dirt and washing the inside and outside of the car and its assemblies and parts, problems (such as abnormal wear, cracks, looseness, etc.) can be found in time, and corresponding measures can be taken to prevent unsafe hazards.

Auto parts cleaning methods are divided into washing, steam washing, solvent washing and chemical washing. Dirt on parts includes: external deposits, residues of lubricating materials. Since these dirts have different properties and characteristics, and often have high adhesion, the ease and methods of removing it from the surface vary.

However, after cleaning, the following requirements should be met:

1. The surface should be spotless, without residual oil stains and scale adhesions, and the intuitive feeling is fresh and refreshing;

2. The surface of all accessories is free of foreign matter, dirt and impurities; after removing the carbon deposits, the metal color can be shown without scratches;

3. All kinds of oil pipes, water pipes and air pipes should be kept clean and unobstructed, without carbon deposits, scale, glue and foreign matter blocking;

4. All protective and filtering devices are kept clean, dust-proof, sound-absorbing and filtering functions freely.

If the above requirements are met, the maintenance quality can be guaranteed.
