  • Patent number: 4675053
    Abstract: A cleaning and scrubbing apparatus is described which consists of a vacuum head to which is coupled small hollow fibers. Each of the fibers has a diameter of approximately the size of the record groove so that it may fit within the record groove to scrub away debris formed within the groove. A cleaning fluid is be placed over the record to partially dissolve the debris so that the fibers can loosen it as the record is rotated across the fibers. The vacuum causes the cleaning fluid including the debris to be sucked through the hollow opening of the fibers. The side walls of the fibers may be a membrane material so that additional fluid flows through the side walls. In order to clean the cleaning head, the fluid is forced in the reverse direction while the head and fibers are facing upright, thereby washing away the debris which has become affixed to the fibers.
