    Abstract: Detergents, especially solid block alkaline detergent compositions, are disclosed comprising a source of alkalinity, and other detergent additives including sequestrants. The detergents of the invention use a mixed condensed phosphate and organic phosphonate sequestrant composition that sucessfully softens service water used in manufacturing aqueous detergents from the composition, but also obtains substantially improved organic soil removal on dishware or flatware. The solid block detergents of the invention comprises large masses of the chemical ingredients having a weight of greater than about 500 grams in a solid block product format that is typically dispensed using a spray on water dispenser that creates an aqueous concentrate that is used in a washing machine.

    Abstract: The invention includes compositions and methods for sanitizing ware without staining, spotting or corroding. In its most preferred mode, the method comprises the steps of washing the ware in an automated ware washing machine and rinsing the ware at either high or low temperatures with a sanitizing rinse composition. The destaining, sanitizing concentrate composition preferably comprises peroxyacetic acid, acetic acid, and hydrogen peroxide using higher levels of acetic and peroxyacetic acid and a lower level of hydrogen peroxide. The sanitizing rinse composition may preferably be used at a concentration of peroxyacetic acid of at least 30 ppm.

    Abstract: A method of sanitizing and destaining ware, including silverware includes the steps of applying a sanitizing concentrate composition to silverware at a rate of 100 ppm to 2000 ppm, the sanitizing concentrate composition including from about 1 wt-% to 20 wt-% of peroxycarboxylic acid, from about 10 wt-% to 50 wt-% of carboxylic acid containing a mixture of acetic acid, and octanoic acid, the acetic acid and the octanoic acid present in a ratio ranging from about 10 to 1 to about 1 to 1, respectively, from about 3 wt-% to 35 wt-% of hydrogen peroxide, and a balance of carrier wherein said peroxycarboxylic acid is the reaction product of the acetic acid, octanoic acid, and hydrogen peroxide.

    Abstract: The invention relates to an aqueous coating composition a film or barrier layer. The aqueous coating, in a pseudoplastic thixotropic mixture having a yield point, can be applied to surfaces in heated food preparation units. The composition can be easily applied to a variety of surfaces, and can advantageously cling to vertical or substantially inclined surfaces in order to form a barrier film or coating. The coating can result in a smooth uniform coating. The film, upon heating forms a barrier layer which can facilitate the removal of food soils which can form during food preparation activities after formation of the barrier film layer. The compositions of the invention can be used in methods for coating the interior heated surface of food preparation units by applying the aqueous material through a spray or other aerosol apparatus to form a clinging aqueous coating. Upon heating, the water from the coating can evaporate leaving an organic/inorganic film which can support baked-on food soil and promote easy removal. The compositions and methods of the invention entail the use of food safe materials approved for contact with comestible substances.
