If all soil and cleaning agent components are soluble, rinsing is dilution. If some components are insoluble, rinsing is also displacement. A client found two minor soil components were heavy oils, insoluble in water. Displacement/rinsing of heavy insolubles with light solubles is equivalent to pushing a chain uphill.
