  • Patent number: 5876514
    Abstract: We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in the rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheeting or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid.

  • Patent number: 5863345
    Abstract: The present invention discloses an alkaline cleaning composition for cleaning heavily soiled surfaces such as food fryers, baking pans, high temperature pasteurizers, beer kettles and similar equipment that normally requires caustic soda based cleaners to clean. The present invention is also useful in cleaning ceramics such as restaurant grade ceramic china plates and platters. The present invention is particularly useful in cleaning brass and aluminum parts and equipment without causing corrosion damage. Further, since the cleaning composition of the present invention is not based on caustic soda, the composition is not considered hazardous. Further, the cleaning composition of the present invention dissolves readily in water, providing a solution that can be used in mechanical sprayers, soak-tanks and clean-in-place equipment. Also the cleaning composition may be effectively used at lower temperatures than caustic cleaning agents.
