A nozzle for generating a supercritical fluid from a cleaning fluid. The nozzle includes a mechanism for directing the supercritical fluid onto a surface of a part to be cleaned. The nozzle comprises a body having (a) an interior portion which includes a mechanism for generating the supercritical fluid by suitable temperature and pressure increase of the cleaning fluid; (b) an inlet portion for introducing the cleaning fluid into the interior portion; (c) an outlet portion for directing the supercritical fluid generated in the interior portion onto the surface of the part to be cleaned; and (d) counteracting mechanism for resisting high pressure that is produced during the generation of the supercritical fluid so as to permit the nozzle to be maintained a suitable distance from the surface of the part to be cleaned so that the supercritical fluid impinges on the surface.
