Cleaning is a commonplace but poorly understood operation in the dairy industries. This paper describes recent work to identify and quantify the critical factors that control cleaning. Experiments have used micromanipulation probes to remove deposits from surfaces; these probes can measure the force required to remove deposits, and allow simple models of cleaning to be produced.
