    Abstract: A rinse agent composition is provided. The rinse agent composition includes a sheeting agent for promoting draining of sheets of water from a surface, and a humectant. The humectant is a component which retains at least 5 wt. % water when the humectant has been contained at an equilibrium of 50% relative humidity and room temperature. The sheeting agent and humectant are preferably provided at a ratio of between about 5:1 and about 1:3. A method for rinsing a substrate surface in the presence of high solids containing water is provided. High solids containing water is generally considered to be water having a total dissolved solids content in excess of 200 ppm.
