Lignin sulfonates can (i) be contained in a liquid multiphase cleaning agent with at least two continuous phases, which has at least one aqueous phase I and an aqueous phase II which is immiscible with this aqueous phase and which can be temporarily converted into an emulsion by shaking , (ii) used in a hard surface cleaner to reduce rain and / or fog, and (iii) in a method to reduce rain and / or fog on a hard surface treated with a liquid cleaner, wherein the surface is treated with a liquid cleaning agent containing at least one alkoxylated dihydroxyaromatic compound of the formula I in concentrated or diluted form, and (iv) in a process for cleaning hard surfaces, in particular glass, in which a cleaning agent according to (i) by Sc shake temporarily transferred to an emulsion, in amounts of 1.5 to 10 g per m · 2 · applied to the surface to be cleaned, preferably by spraying, and this surface is then optionally cleaned by wiping with an absorbent soft object. |
