An alkaline sensitive metal cleaning composition is provided. The alkaline sensitive metal cleaning composition contains an alkaline concentrate and a corrosion inhibitor concentrate. The alkaline concentrate includes a source of alkalinity in an amount sufficient to provide a use solution having a pH of at least 10.0, and a first chelant component that exhibits soil removal properties when used at a pH of at least 10.0. The corrosion inhibitor concentrate includes a corrosion inhibitor component for reducing corrosion of alkaline sensitive metals when used in a use solution having a pH of at least 10.0, a second chelant component for stabilizing the corrosion inhibitor in the corrosion inhibitor concentrate when the corrosion inhibitor concentrate is provided at a pH that is less than 8.0, and a surfactant component for providing cleaning properties when used at a pH of at least 10.0. A threshold inhibitor/crystal modifier can be provided in at least one of the alkaline concentrate and the corrosion inhibitor concentrate to stabilize the corrosion inhibitor in a use solution at a pH of at least 10.0. A method for cleaning an alkaline sensitive metal surface and a washing facility are provided. |
