    Abstract: OIL IMPREGNATED TEXTILE CLEANING UTENSILS CAN BE CLEANED AND PREPARED FOR REUSE IN A SINGLE BRIEF OPERATION BY USING A PETROLEUM MINERAL OIL AS THE CLEANING MEDIUM. THE UTENSILS ARE CLEANED BY PLACING THEM INTO THE WHEEL OF A COMMERCIAL DRY CLENAING APPARATUS THEN ADDING AN EXCESS OF OIL BEYOND THAT NECESSARY TO SATURATE THE UTENSILS AT A TEMPERATURE BETWEEN 60-250*F. AND AGITATING THE WHEEL FOR ABOUT 15 MINUTES. THE OIL IS DRAINED OFF AND THE UTENSILS ARE SPUN TO REMOVE EXCESS OIL BUT LEAVE ABOUT 20 TO 40 WT. PERCENT OIL IN THE UTENSIL BASED ON THE WEIGHT OF THE CLEAN, DRY UTENSIL OR IMPLEMENT.

    Abstract: A system and method are provided for separating water from solvent during dry cleaning. Included is an inlet (52) capable of receiving a mixture of dry cleaning fluid and water from a basket of a dry cleaning apparatus. The dry cleaning fluid includes a siloxane composition. Also provided is a flow controller (60) for urging flow of the mixture received from the outlet. Coupled to the flow controller (60) is a coalescent media (64) that receives the mixture urged by the flow controller (60). A chamber (68) is coupled to the coalescent media (64) for receiving the mixture from the coalescent media (64) to separate the water and the dry cleaning fluid. Also coupled to the chamber (68) is an outlet (69) to remove the dry cleaning fluid from the chamber (68) in the absence of water.
