<p>The invention is directed to stabilized concentrated cleaning solutions comprising a source of hypochlorite ions and to a method for providing the stabilized concentrated cleaning solutions. The stabilized concentrated cleaning solutions according to the invention comprise a hydroxide ion source, hypochlorite ion source, and a chelating agent, and are provided simply by mixing the various components together. The stabilized concentrated cleaning solutions exhibit stability against, e.g., dilution with a diluent comprising amounts of copper, iron, nickel cobalt, etc., as well as storage for periods of from about 10 weeks to up to about 1 year without undergoing visible deterioration and/or a substantial deterioration in efficacy.</p> |
