Dependent claims

A method for cleaning using a cleaning compound from an in situ cleaning system comprising:

(a) providing feed water to an in situ cleaning system said cleaning system comprising one or more of:
(i) a water treatment component, wherein the water treatment component comprises a treatment reservoir comprising one or more conversion agents selected from the group of metal oxides, metal hydroxides, and mixtures thereof;
(ii) an oxidizing agent generating component;
and
(iii) an alkalinity generating component, wherein the alkalinity generating component further comprises a decomposition agent selected from the group consisting of a source of manganese, a source of silver, and combinations thereof, wherein the decomposition agent catalyzes the decomposition of an oxidizing agent to form a source of alkalinity when contacted with the oxidizing agent;
wherein the cleaning system provides a use solution;
and
(b) contacting an article with the use solution and;
(c) washing the article in a washing system.
