ABSTRACT:
An object to be cleaned is cleaned with an cleaning agent which mixes a base cleaning agent such as silicon-containing cleaning agent or an isoparaffin containing cleaning agent with a surfactant or a hydrophilic solvent to promote the cleaning power. The object is rinsed with the base cleaning agent alone after it goes through the first cleaning step as described above. Then, this is followed by the finishing treatment by the use of hot air or steam drying. The base cleaning agents can be recovered and recycled, improving economy in the case with the use of two or more cleaning agents in combination. The excellent properties of degreasing and dewatering, comparable to those of flon system, can be obtained using a mixture of silicon-containing or isoparaffin-containing cleaning agents with surfactants and hydrophilic solvents and maintaining safety in environment.
