    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 rinse aid composition for use on plasticware is herein described which requires lower concentration of conventional hydrocarbon surfactants, exhibits adequate sheeting on the plasticware and acceptable drying time which prior rinse aids have failed to provide without special handling. The compositions described contain hydrocarbon surfactants and a polyether or polybetaine polysiloxane copolymer surfactant alone or in combination with a fluorinated hydrocarbon surfactant The composition may be formulated as a solid or liquid suitable for dilution to form an aqueous rinse used to contact the plasticwa re in a warewashing machine.
