A dry cleaning apparatus utilizing perchlorethylene recovery process for striping spent filter cartridges in which virtually all of the perchlorethylene is recovered from the spent cartridges so as to increase the economic efficiency of the system while at the same time reducing the hazardous to both environment and the operator's health. As a result the instant invention leaves the spent filtering cartridges so entirely free of perc that these cartridges can be discarded with regular trash without any health hazard to the general public at large et cetera. In one embodiment of the invention a set of valves are ganged together by linkage so that two separate set of filter cartridges may be kept connected to the system so that a fresh set may be immediately switched into a cleaning cycle while a spent set is being stripped of any perc.
