The report documents actions taken by Robert Bosch Corp., Charleston, SC, in replacing the cleaning solvents, 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113) and trichloroethylene (TCE) with aqueous solutions. An early key decision was to replace their aging, large central degreasing stations with several small cleaning units, each designed and dedicated for cleaning just one part at one step in the product assembly process. The strategy demanded reassessment of each cleaning step and identification of apparatus and chemistry for optimizing each aqueous replacement. The report summarizes the actions taken to achieve aqueous cleaning for four typical components, previously cleaned with chlorinated solvents. The report provides quantitative comparisons of cleaning performance and costs of the old chlorinated (1988) and the new aqueous (1992) cleaning methods.
