Such chlorinated solvents as methylene chloride, trichloroethylene, and 1,1,1-trichloroethane have traditionally been used to clean components in the metalworking industry. However, there is now evidence that exposure to these compounds can cause health problems, and OSHA has established occupational vapor-exposure guidelines for them. Used solvent- based cleaners also constitute a hazardous waste. Therefore there exists a demand for alternative nonchlorinated solvent cleaners. New water-based cleaning substances have been compared to conventional chlorinated solvents on the basis of filtration properties, soil holding, and general cleaning efficiency. The water-based cleaners most often consist of corrosion inhibitors, alkalinity builders, water conditioners, and organic surfactants.
