Estimating the term…
A warewashing composition includes a cleaning agent having a detersive amount of a surfactant, an alkaline source in an amount effective to provide a use composition having a pH of at least about 8 when the use composition is measured at a solids concentration of about 0.5 wt %, and a corrosion inhibitor in an amount sufficient for reducing corrosion of glass when the warewashing composition is combined with water of dilution at a dilution ratio of at least about 20:1 water of dilution to detergent composition o form a use composition. The corrosion inhibitor includes a salt of calcium, magnesium, or a mixture of calcium and magnesium. The salt has a water solubility of less than about 0.5 wt % in water at about 20° C. and atmospheric pressure so that the salt precipitates to form a protective layer on a substrate in contact with the use composition.
