Abstract
The present invention relates to a composition for cleaning surfaces and/or for detecting organic substances in a solution or on a surface, comprising a) at least one salt of the permanganic acid, ferric acid and/or chromic acid, b) at least one organic phosphonate and c) at least one persulphate, wherein the at least one organic phosphonate has a general formula (I) wherein R1 is an organic moiety, X1 is OH or OM1 and X2 is OH or OM2, wherein M1 and M2 represent an alkali metal ion or ammonium ion, wherein the organic moiety R1 is a mono-substituted or multiple-substituted or unsubstituted C1-C12 alkyl moiety, C3-C10 cycloalkyl moiety or C6-C14 aryl moiety, wherein the organic moiety may be attached to 1 to 3 further phosphonate groups of the general formula (I).
