ABSTRACT:
A method for cleaning plasticware wherein the rinse cycle employs a rinse aid composition 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 contain hydrocarbon surfactants and a combination of a fluorinated hydrocarbon surfactant and a polyalkylene oxide-modified polydimethylsiloxane surfactant. The composition may be formulated as a solid or liquid suitable for dilution to form an aqueous rinse used to contact the plasticware in a warewashing machine.
