Abstract

Use of a complex of formula I for removing cooked-, baked- and burnt-on proteinaceous soils from surfaces, in which M stands for Al, or a transition metal, or a lanthanoid metal, n stands for a number in the range of 1 to 5, L stands for a ligand according to formula II, in which E is selected from O, NR <1> , and mixtures of them, w stands for a number in the range of from 0 to 2, and R <1> is selected from H, optionally substituted C <1-20>-alkyl or heteroalkyl groups, optionally substituted C <2-20>-alkenyl, heteroalkenyl or alkinyl groups, optionally substituted aryl or heteroaryl groups, and optionally substituted C <1-20>-alkylaryl or heteroaryl groups, m stands for a number in the range of from 0 to 3, A stands for an alkali metal cation and q stands for 1, an earth alkali metal cation and q stands for 2, or an ammonium cation and q stands for 1, X <v-> stands for an anion selected from the group of F <->, CI <->, Br <->, I <->, OH <->, HSO <3>- , SO <3>2- , SO <4>2- , HSO <4>- , NO <2>- , NO <3>- , PO <4>3- , HPO <4>2- , H <2>PO <4>- , BF <4>- , PF <6>- , ClO <4>- , organic anions such as acetate, citrate, formiate, glutarate, lactate, malate, malonate, oxalate, pyruvate, tartrate, methanesulfonate, methyl sulfate, tosylate, succinate and their mixtures, with v being 1, 2 or 3, respectively, and p and r, irrespective of each other, are numbers in the range of from 0 to 7, selected such that the charge of the complex according to formula I is 0.
