Rinsing and Drying Issues and Answers

T he ban on chlorofluorocarbons (CFCs) hit users squarely in their degreasers. In the search for viable alternative cleaning processes, the first task was to determine evaluation criteria. When is a product sufficiently clean? How do we know when it’s properly rinsed? At what point is it adequately dry? After seeking out suitable non-CFC cleaning agents, we next sized up equipment best suited for them. The rinsing process looked very simple with minimum technical risk. The last consideration in the conversion plan was drying. On the surface, drying appeared the most straightforward of the three phases of the cleaning process, with a multitude of “industry proven” methods available. But good drying integral to successful precision cleaning is a complex necessity.
