We described the use of water-soluble graft copolymers prepared by free-radically initiated graft polymerization of from 40 to 90% by weight of component (A) selected from the group of monosaccharides, oligosaccharides, polysaccharides and their derivatives, with from 5 to 40% by weight of monomers ( B), selected from the group of ethylenically unsaturated C3-C10 monocarboxylic acids or their alkali metal or ammonium salts, and 10 to 50 wt .-% of monomers (C) selected from the group of ethylenically unsaturated N-containing monomers, and / or containing sulfo groups ethylenically unsaturated monomers, in cleaning compositions which contain at least one surfactant component in addition to the graft polymer, for hydrophilizing and / or improving the gloss retention of hard surfaces which have been brought into contact with these cleaning agents |
