Abstract
The application of co-polymers of i) unsaturated carboxylic acids, ii) monomers containing a sulphonic acid group and iii) optionally further ionic or non-ionic monomers in cleaning agents for machine dishwashing, in combination with builders and non-ionic detergents and/or homo- and/or co-polymers of acrylic acid and/or methacrylic acid, or the salts thereof gives rise to advantageous effects, even when the co-polymer is used in the main cleaning cycle.
