Abstract
A cleaning and disinfecting article of manufacture and method are provided wherein the cleaning and disinfecting article of manufacture comprises a cleaning and disinfecting ingredient which includes a cleaning and disinfecting agent, a solid color indicator composition which includes a color indicator agent and a matrix agent supporting the color indicator agent, wherein the matrix agent is a matrix salt; and a stabilizing salt. The cleaning and disinfecting ingredient has a bleaching tendency relative to the color indicator agent such that when the solid color indicator composition is in an aqueous solution of the cleaning and disinfecting ingredient, the presence of the cleaning and disinfecting ingredient in the solution minimizes the display of color in the solution for as long as significant amounts of the cleaning and disinfecting ingredient are present. The continued release of the color indicator agent from the solid color indicator composition after depletion of the ingredient results in a substantial display of color whereby the depletion of the cleaning and disinfecting ingredient can be detected, and such that when the stabilizing salt is in the solution, the cation of the stabilizing salt in the solution displaces the cation of the matrix salt in the solid color indicator composition.
