An process for treating or cleaning fabric articles, especially articles of clothing, linen and drapery, wherein the method comprises contacting the fabric articles to be cleaned or treated with a cleaning fluid comprising a lipophilic fluid and removing from the fabric articles a portion of the cleaning fluid. The discontinuous phase contains a liquid oxidizer other than an inorganic oxidizer salt. The machine tool may also include a cutting tool movable along a tool path for removing a volume containing the out-of-tolerance area. The processor may receive the compare data structure and the associated tolerances. Significantly, because the etch resistance of hardened patterned photoresist is higher than that of the non-hardened patterned photoresist, the method can improve any defect induced by etched photoresist during the pattern transferring process. A hydrogen-containing gas is generated in the gas generation system from a starting material which contains at least a proportion of liquid hydrocarbon as fuel.
