Removal of dirt mainly composed of organic substances such as oils and fats present on solid surfaces such as precision parts and jigs is performed by removing hydrocarbon solvents such as kerosene, benzene and xylene; chlorine solvents such as trichloroethylene and tetrachloroethylene; A fluorocarbon-based solvent such as fluoroethane; a water-based detergent obtained by mixing a surfactant or a builder with sodium orthosilicate or caustic soda is used. In particular, fluorocarbon-based solvents or chlorine-based solvents are used for components such as electronics, electricity, and machinery, taking advantage of their high cleaning properties and flame retardancy.

In addition, hydrocarbon solvents, especially benzene and xylene, are highly toxic and are designated as hazardous substances under the Industrial Safety and Health Law. It is not preferable to use it as an agent. On the other hand, an aqueous detergent is preferable in that it has a lower risk and toxicity than a solvent-based detergent, but is inferior in detergency by several steps.
