Abstract The paper summarizes the demonstration of an innovative parts cleaning technology with a more benign process to replace environmentally damaging chemicals. The process has the potential to replace 1,1,1-trichloroethane (TCA), an ozone-depleting compound, a hazardous air pollutant, and 1 of the 17 chemicals on EPA's 33/50 list of priority pollutants. Carbon dioxide (CO2), in a liquid or supercritical form, has significant surface cleaning properties. Liquid CO2 (LC02) is distinct from supercritical CO2 because it can be maintained at lower pressures and temperatures than supercritical. Both have the advantage of permeating tiny holes (e.g., a gas) and have good solvency for many oils, greases, and other contaminants.
