Abstract
Process for cleaning dishware soiled with fatty residue, characterized in that said process is carried out at a temperature in the range of from 45 to 65° C. and using at least one formulation, comprising (A) in the range of from 1 to 50% by weight of at least one complexing agent, selected from the alkali metal salts of citric acid, aminocarboxylic acids and from sodium tripolyphosphate, (B) in the range of from 2 to 8% by weight of at least one non-ionic surfactant of general formula (I) R—CH(OH)—CH—O-(AO)—R(I) (C) in the range of from 0.25 to less than 4% by weight of a copolymer, being obtained from copolymerizing the following comonomers (a) at least one comonomer selected from ethylenically unsaturated C-C-carboxylic acids and ethylenically unsaturated C-C-dicarboxylic acids or their respective anhydrides, (b) at least one comonomer selected from isobutene, diisobutene, C-C-a-olefins, and C-C-alkyl esters of (meth)acrylic acid, (c) optionally, at least one further comonomer selected from non-ionic comonomers, the integers being defined as follows: Rbeing selected from C-C-alkyl, straight-chain or branched, and from C-C-alkenyl, straight-chain or branched, with at least one C—C double bond, Rbeing selected from C-C-alkyl, straight-chain or branched, and from C-C-alkenyl, straight-chain or branched, with at least one C—C double bond, x being selected from one to 100, AO being identical or different alkylene oxides, selected from CH—CH—O, (CH)—O, (CH)—O, CHCH(CH)—O, CH(CH)—CH—O— and CHCH(n-CH)—O.R—CH(OH)—CH—O-(AO)—R  (I)
