  • Patent number: 5397506
    Abstract: Improved cleaners for hard surfaces, cooking utensils, laundry and other substrates that can accumulate fatty soils can be cleaned using an aqueous cleaner made from a cast solid cleaning system. The cast solid system contains a carefully balanced formulation of cleaning ingredients that provide surprising animal or vegetable fat removing properties. The cleaning system can be manufactured in the form of a large bulk cast block. Such blocks are dispensed by spraying a dispensing spray of water onto the surface of the block creating an aqueous concentrate that can be directed to a cleaning site. The solid composition contains a unique blend of a specific amine oxide combined with anionic sulfonates in a solvent containing mass. These unique components cooperate to provide a substantial level of animal or vegetable fat removal in preferred cleaning protocols.
