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.
