Abstract:

In the past, solvents have been used to clean oils and greases, soils, inorganic salts, and foreign particles from manufactured materials or parts. However, increased awareness of the health, safety, and environmental issues surrounding the use and disposal of solvents has stimulated a search for alternatives. Many parts cleaning practices that once relied on petroleum-based solvents can also be done with aqueous cleaning. Petroleum-based solvents depend largely on their abilities to dissolve organic contaminants, while aqueous cleaning uses water as the primary solvent and a combination of water conditioners, detergents, and surfactants to promote better cleaning of the metal object. This research evaluated automatic aqueous parts washers, sometimes called jet washers, currently in use at U.S. Army installations. The study found that users are generally satisfied with the performance of these washers and that the washers are relatively low maintenance. Recommendations were made to optimize the use of automatic aqueous parts washers.
