Abstract

Disclosed is the use of water-soluble graft copolymers prepared by free-radically initiated graft polymerization of 40 to 90% by weight of component (A), selected from the group consisting of monosaccharides, oligosaccharides, polysaccharides and derivatives thereof, with 5 to 40% by weight of monomers (B), selected from the group consisting of ethylenically unsaturated C3-C10 monocarboxylic acids or the alkali or ammonium salts thereof, and 10 to 50% by weight of monomers (C), selected from the group consisting of ethylenically unsaturated N-containing monomers and/or ethylenically unsaturated monomers containing sulfo-groups, in cleaning compositions which, as well as the graft polymer, comprise at least one surfactant component, for hydrophilization and/or improvement of shine retention of hard surfaces which have been brought into contact with these cleaning compositions.
