Fast drying and fast draining rinse aid comprising a mixture of alkoxylated alcohol surfactants
The present invention is directed to rinse aid compositions and methods for making and using the rinse aid compositions. The compositions of the invention include a sheeting agent, a defoaming agent, and an association disruption agent. The rinse aid compositions of the present invention result in a faster draining/drying time on most substrates compared to conventional rinse aids. The rinse aid compositions of the present invention are especially suitable for use on plastic substrates.
