Beschreibung
Zusammenfassung:	The present invention is directed to an aqueous rinse composition having a pH of from 8 to 12 which is obtained by forming a mixture comprising:i) at least one inorganic base;ii) at least one water soluble compound according to general formula (IIA) or a water soluble salt thereof, wherein R1, R2 and R3 are independently selected from H or C1-C6 alkyl, and / or at least one water soluble compound according to general formula (IIB) or a water-soluble salt thereof, wherein R4 is selected from H or C1-C6alkyl;iii) at least one water-soluble polyphosphonic acid or a water-soluble salt thereof, wherein said polyphosphonic acid has the general formula (III) in which n is at least 2 and Z is a connecting organic moiety having an effective valency of n, further wherein said polyphosphonic acid is characterized in that at least two phosphonic groups are separated by an alkylene bridge having 1 or 2 carbon atoms (C1-C2 alkylene); and,iv) water.
