    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 1 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. In addition, to use as a dewatering cleaning agent, the low molecular weight polyorganosiloxane is additionally mixed alone or with a surfactant and/or a hydrophilic solvent. Accordingly, cleaning and water substituting properties equivalent to flon containing dewatering cleaning agents and environmental safety can be obtained.

    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.
