The VPI HW17 is a machine that only lunatic fringe analog music lovers will know about. You put the record on it, then spread some cleaning fluid around the record. Then give it a really good scrubbing making sure to get down in the grooves and loosen up any sediment that may be down there. Then you move the pick-up tube into place and throw the switch marked "vacuum" and unleash mechanical mayhem as all the cleaning fluid (and the now suspended sediment) gets sucked off of the playing surface and safely into the machine where you can dispose of it later.
