ABSTRACT OF THE DISCLOSURE A hard surface cleaning composition forming upon agitation a relatively unstable emulsion breakable when applied to the hard surface to be cleaned comprising on a weight basis from about 2 to about 10% of an organic polar solvent; from about 0.1 to about 2.0% of a volatile organosiloxane; from about 0.1 to about 2.0% of a volatile surfactant having the formula: Image wherein R1 is an alkynyl of from two to five car- bons; R2 is hydrogen or an alkyl of less than four carbons, and R3 is an alkyl or hydroxy alkyl of from one to eight carbons, the total number of carbons being from four to twelve, and water, the ratio of said volatile surfactant to said volatile organosiloxane being between about 3:1 to about 1:3. The preferred volatile surfactant is 3,5-dimethyl-1-hexyn-3-ol, while the preferred siloxane is the dimethyl siloxane cyclic tetramer. Preferably, the polar solvent is a solvent system comprising a low boiling solvent and a high boiling solvent. Optional constituents include builder salts, alkalinity agents, dye and perfume. After shaking, the emulsion formed is applied to the surface and wiped with a cloth, paper towel or sponge. The breaking of the emulsion and the eva- poration of the volatile constituents is demonstrated by a bubbling action that is believed to assist in the cleaning of the surface.
