This project report details results of investigations into alternatives to chlorinated solvents used for metal degreasing. Three companies participated in this project. The results reported for one company document a situation where the conversion to an aqueous cleaning system had already been implemented. Those for a second company provide real-time information about the conversion from an intermediate solvent to an aqueous system. Finally, results for the third company contribute information about alternatives that must be applicable to a variety of substrates and configurations. In addition to the technical evaluations, the project report provides financial analyses and environmental impact assessments on the cleaning alternatives. For the financial analyses, the Total Cost Assessment methodology was used which includes many important environmental costs not typically included in a financial analysis. A substitution analysis methodology that provides qualitative results was developed and used to evaluate the environmental, occupational, and public health effects of the alternative cleaning processes.
