Alkoxylated aromatic dihydroxy compound corresponding to formula I: (see formula I) in which X is a single bond, a C1-5 alkylene group, a carbonyl group or a group C-R1, where R1 is a hydrogen atom or a C1-6 alkyl group, Y is a single bond, a C1-5 alkylene group, a carbonyl group, a group C-R2, where R2 is a hydrogen atom or a C1-6 alkyl group, or two hydrogen atoms, the group "-Y-" then corresponding to "-H H-", R is a hydrogen atom, a C1-6 alkyl group or mixtures thereof, m is a number of 0 to about 20 and n is a number of 0 to about 20 and the sum of m + n > 0, may be used (i) in a liquid multiphase cleaning composition with at least two continuous phases which contains at least one aqueous phase I and a non-aqueous liquid phase II immiscible with this aqueous phase and which can be temporarily converted into an emulsion by shaking, (ii) in a composition for cleaning hard surfaces to reduce the rain effect and/or the film effect, (iii) in a process for reducing the rain effect and/or the film effect on a hard surface treated with a liquid cleaning composition, the surface being treated with a liquid cleaning composition in concentrated or diluted form containing at least one alkoxylated aromatic dihydroxy compound corresponding to formula I and (iv) in a process for cleaning hard surfaces, more particularly glass, in which a cleaning composition according to (i) is temporarily converted into an emulsion by shaking, applied to the surface to be cleaned, preferably by spraying, in quantities of 1.5 to 10 g per m2 and the surface is then optionally cleaned by wiping with a soft absorbent material.
