1. A method for cleaning, sanitizing, and/or removing stains from tableware comprising the steps of:

  • A) forming an aqueous solution from a solid controlled release automatic dishwashing composition comprising;

    (a) at least about 0.1%, by weight of the composition, of a halogenated salt which is calcium chloride or magnesium chloride;

    (b) a component selected from the group consisting of a builder, suds suppressor, perfume, enzyme, bleach-scavenging agent, a metal-protecting agent, and mixtures thereof;

    (c) a dissolution control material; and

    (d) at least one adjunct ingredient;

    wherein said automatic dishwashing composition is free of bleach, and is in the form of a solid controlled release pill or tablet housed in a porous basket;

    B) allowing said aqueous solution to pass into an electrochemical cell and/or electrolytic device during the wash and/or rinse cycle, thereby forming an electrolytic solution comprising halogenated mixed oxidants; and

    C) contacting tableware with said electrolytic solution.
