Abstract

Complexes of the transition metals cobalt, iron, copper, and ruthenium having at least one and preferably at least five ammonia ligands are used to activate peroxygen compounds in aqueous cleaning solutions for hard surfaces. Compositions preferably contain 0.0025% to 0.25 by weight of the activating complex.
