The purpose of cleaning precision hardware parts is to remove surface stains. Different cleaning fluids need to be selected according to the cleaning objects. There are two types of cleaning fluids: aqueous cleaning fluids and solvent-based cleaning fluids. Hydrocarbon metal cleaning agent has a good degreasing effect and has a corrosion inhibition effect on steel and other metals. No corrosion to equipment, copper, stainless steel and other parts of different materials during cleaning, easy to operate, safe and reliable.

The main methods of degreasing and degreasing of hardware and metal are: organic solvent method, chemical method, electrochemical method, and water-based cleaning agent cleaning method. The common organic solvent trichlorethylene cannot completely remove the polishing wax, especially the metal on the metal surface. Does not remove oxides, carbides, and abrasives effectively; trichlorethylene is not only more toxic, but also has a tendency to hydrolyze improperly and is corrosive to metals in wet conditions.

The ultrasonic cleaning process of hardware parts is the interaction between cleaning medium, contaminants and part appearance. This is a complex physical and chemical process, the purpose of which is to make the appearance of metal stamping parts after ultrasonic cleaning reach a certain level of cleanliness.
