Abstract: A cleaning composition comprising at least one low molecular weight polyorganosiloxane selected from the group consisting of straight chain polydiorganosiloxane represented by a general formula: ##STR1## (wherein R.sup.1 is an organic group of single valence substituted by the same or different group or unsubstituted, and l is an integer from 0 to 5), and cyclic polydiorganosiloxane represented by a general formula: ##STR2## (wherein R.sup.1 is an organic group of single valence substituted by the same or different group or unsubstituted, and m is an integer from 3 to 7). To use it as a water system cleaning agent, polyoxyalkylene group containing polyorganosiloxane, a surfactant, and water are additionally mixed. Accordingly, a cleaning effect free from environmental destruction and contamination, equivalent to flon containing cleaning agents, and satisfactorily stable in terms of dispersion as a water system cleaning agent can be obtained.

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.

Abstract: The detergent of this invention, directed to the cleaning of an object having a gap portion at least in part thereof, contains at least one of components of the detergent having a solubility parameter difference of not more than 3 from and a contact angle within 15.degree. with at least one of components of a smear on the object. The detergent provides an ideal cleaning for the object because it easily permeates into and dissolves the machining oil filling the gaps between closely cohering thin metallic strips. The method of cleaning according to the invention has first cleaning the object with a polar detergent and then rinsing and drying the cleaned object with a detergent having low polarity or no polarity. In the precision cleaning of such objects as electronic parts, therefore, it manifests satisfactory cleaning and drying properties.

Abstract: A part still wet with water or an aqueous type detergent adhering to the surface thereof is drain washed in a washing tank using a hydrophobic dewatering cleaning agent. In this operation of dewatering cleaning, the hydrophobic dewatering cleaning agent stored in the washing tank is circulated between the washing tank and a reserve tank to deprive the hydrophobic dewatering cleaning agent of water entrained thereby by means of a concentration type filter inserted in a path laid for the circulation. A hydrophobic filter is mainly used as the concentration type filter. The dewatering cleaning is continued and meanwhile the consequently isolated hydrophobic dewatering cleaning agent is exclusively returned to the washing tank. As a result, the water concentration in the hydrophobic dewatering cleaning agent stored in the washing tank can be constantly kept below a prescribed level.
