    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 cleaning apparatus then adding an excess of oil beyond that necessary to saturate the utensils at a temperature between 60250*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.
