ABSTRACT
All aqueous cleaning processes involve three steps: washing, rinsing, and drying. ¤e focus of most laboratory tests is to determine what must be done in the wash phase to actually remove contamination from the part while rinsing is o¨en done in the most expeditious manner possible. Equipment constraints and material availability may dictate that only a few parts are cleaned using whatever equipment is available in the laboratory. Sometimes only one or two parts are cleaned using temporarily available production equipment from another application. On the surface, this might seem to be a path leading toward failure, but, just by applying a few well-known tools, the results of the cleaning tests can be scaled up to satisfactorily handle the full, ongoing production requirements. ¤e purpose of this chapter is to provide these tools. While the discussion focuses on scaling up and automating a batch aqueous
immersion washing and rinsing process, many of the principles can be applied to other aqueous and solvent cleaning processes.
