Abstract: A portable golf ball washing device includes a generally elongated cylindrical container within which a pair of bristle modules are disposed with the bristles of each module including a short bristle segment and a long bristle segment to define two separate concentric zones within the container. A ball carrying paddle is provided with a ball receiving opening adjacent one end thereof and a closure member with appropriate handle means attached thereto at the opposite end. The paddle is dimensioned to extend into the receptacle and support the ball for rotative movement during the washing action. An appropriate cleaning solution is disposed within the container for assisting in the washing action when the paddle is moved longitudinally of the container and the ball engages the several bristle zones.
