Abstract

This article describes an innovative displacement method for removing surface contaminants and for drying cleaned parts. Displacement of hydrophobic solvent with a hydrophilic aqueous displacement solution (ADS) has made it possible to use open tank systems to use environmentally safe solvents to clean a variety of contaminants. The solvent ADS method has shown to clean both tenacious organic and inorganic contaminants that are difficult to remove using only aqueous processes. The ADS has made it possible to dry parts cleaned with high boiling point solvents at a ...
