INTRODUCTION
As the old expression goes, “The job ain’t over ‘til the paper work’s done.” This axiom can also be applied to cleaning. A great deal of effort has been expended this far in determining the appropriate cleaning chemistry and its suitability for the soil encountered and its environmental impact. In addition, the appropriate rinsing of the chemical has been discussed. Having fully analyzed and tested the cleaning and rinsing aspects, the method of drying the part needs equally dedicated review.
