Initially, process parameters for dense phase fluid cleaning are determined. Thereafter, a cleaning chamber containing a substrate is pressurized with a dense phase fluid, based on these process parameters. The substrate is then cleaned with the dense phase fluid, again based on these process parameters. Exhaust fluid is subsequently expelled from the cleaning chamber, and thereafter analyzed. The process parameters are then adjusted to adjusted process parameters based on the analysis of the exhaust fluid. Thereafter, the cleaning chamber is again pressurized and cleaning repeated. This pressurization and cleaning is based on the adjusted process parameters. Also, this pressurization and cleaning is repeated until the substrate is sufficiently clean.
