ABSTRACT:
Workpieces are loaded into a cleaning chamber. The cleaning chamber is pressurized with a first dense-phase cleaning fluid, the temperature and pressure of the first dense-phase fluid being maintained at less than about 1500 psi using a temperature control device. The workpieces are soaked in the first dense-phase fluid for a predetermined time period. After soaking, the workpieces are further cleaned by applying a second, localized, high-pressure dense-phase fluid to the surface of the workpieces.
