In one embodiment of a putter the putter comprises a head, a cap, at least one brush insert, and a handle. The brush insert(s) may be positioned between the head and cap and retained by the engagement of the cap with the head. The head and cap may be formed with respective ball apertures such that a golf ball may pass through those apertures. The brush insert, which is replaceable, may be formed with a plurality of radially oriented brushes having distal ends extending inward. The putter may be used to retrieve a golf ball from a golf cup by lowering the putter into the cup and forcing the golf ball into the brush insert. Subsequently removing the golf ball coupled with inserting the golf ball into the brush insert cleans the golf ball.
