The present invention provides a cleaner having a hopper for receiving dirty product to be cleaned. The hopper feeds the dirty or contaminated product downwardly onto a cleaning comb that directs the larger sized contaminants onto the exterior surface of a scalping reel having a plurality of apertures of a preselected size and shape. The dirty or contaminated material falls through the screen openings into the interior thereof and on out through the screen at the bottom thereof as it rotates. The dirty or contaminated material is then directed into a vertically oriented aspiration column that has a negative airflow from the bottom thereof upwardly. Fines, chaff, and other light contaminants are carried upwardly by the negative airflow and out of the product, which drops on downwardly into an outlet into a storage facility or onto a conveyor as desired by the cleaner operator. A vacuum nozzle is disposed in close proximity to the scalping reel to remove contaminants that may become lodged in the apertures. The vacuum nozzle is connected to the outlet of the aspiration column.
