Abstract
A washer for balls such as golf balls including an entry tube having an open entrance end and a second end joined at an angle to an adjoining end of an exit tube thereby forming an elbow-shaped housing. The exit tube has an inner wall lined with brushes near the adjoining end and sponges near the exit end. A rotatable helical (spiral) array of brushes, or/and sponges, is arranged inside of and concentric with the exit tube. The washer is supported with the entrance and exit above the joining ends so that the housing will hold water up to a level that is determined by a weep hole to keep the brushes submerged. The helical array of brushes can be turned manually by a crank extending from the central shaft of the helical brush array to function as a lift mechanism. Balls are inserted into the entrance end of the housing and as the handle is turned, the ball is scrubbed as it is lifted by the helical brush array toward the exit end of the housing onto a sponge-lined tray having weep holes therein.
