Abstract

The invention relates to liquid multiphase, essentially CFC-free detergents with at least two continuous phases. The detergents have at least one aqueous phase (I) and a non-aqueous liquid phase (II) that is immiscible with phase (I), and can be temporarily transformed into an emulsion by shaking. They also contain an anionic and/or non-ionic surfactant and are suitable for use in a method for cleaning hard surfaces, especially glass. According to said method, the inventive detergent is shaken to produce the temporary emulsion and applied to the surface to be cleaned in quantities of 1.5 to 10 g per m{circumflex over ( )}2, preferably by spraying. The surface is then cleaned, optionally by wiping with a soft, absorbent object.
