| Abstract: |
Disclosed are granular automatic dishwashing detergent compositions containing an insoluble inorganic zinc salt useful for inhibition of glassware corrosion in the dishwasher. These compositions are particularly desirable because use of them in the dishwasher does not result in precipitation of zinc insolubles on the dishware or dishwasher parts.
