As an extremely important part of the remanufacturing, the quality of remanufacturing cleaning directly affects the quality of remanufacturing products. The paint is an essential dirt type in remanufacturing cleaning. Compared with other dirt types, the paint has the characteristics of combining with the matrix for a long time, complex bonding condition and difficult cleaning. At present, the traditional cleaning technology is mainly used in paint cleaning, such as acid and alkali solution cleaning, high-temperature thermal decomposition, dry shot peening cleaning and so on. But the popularization and application of paint green cleaning technology appeared in recent years is not enough, and there is no systematic summary to guide the practical application. Aiming at the status, based on the research results of domestic and foreign scholars on paint green cleaning technology, the paper summarizes the properties of paint first, such as the combination of paint and matrix, surface micro morphology and main components of paint. Then it summarizes the commonly used paint green cleaning technology of the mechanical field, such as molten salt cleaning technology, dry ice cleaning technology, laser cleaning technology, high pressure water jet cleaning technology, wet shot peening cleaning technology, ultrasonic cleaning technology and supercritical CO2 cleaning technology that focus on the paint cleaning mechanism of all kind of cleaning technologies and their respective advantages and disadvantages. And taking the cleaning efficiency as the measurement standard, this paper makes a simple comparative analysis of various cleaning technologies, which provides the reference for users to choose cleaning technologies. Finally, according to the limitations of the existing paint cleaning technology, the development prospect of the cleaning technology is prospected, and the development concept of green, compound and intelligent is proposed, which provides ideas for the promotion of new paint cleaning technology and the improvement of existing paint cleaning technology, so as to facilitate the further development of cleaning technology.
