摘要：
A warewashing detergent composition is provided according to the invention. The warewashing detergent composition includes a cleaning agent, an alkaline source, and a corrosion inhibitor. The cleaning agent comprises a detersive amount of a surfactant. The alkaline source is provided in an amount effective to provide a use composition having a pH of at least about 8. The corrosion inhibitor includes a source of aluminum ion and a source of zinc ion. The relative amounts of the source of zinc ion and the source of aluminum ion can be controlled to reduce visible filming when the warewashing detergent composition is used in the presence of hard water. Methods for using and manufacturing a warewashing detergent composition are provided.
