Abstract: Portable golf club head cleaner includes a body having a location for receiving a golf club head and a reservoir for holding a liquid. A brush for cleaning the golf club head includes means for moveably mounting the brush within the body, adjacent the location. Pumping means pump liquid from the reservoir onto the brush on operation of manually operable means which simultaneously pumps the pumping means and moves the brush to clean a golf club head at the location. The brush may move in a reciprocal manner or may be cylindrical in shape and move by rotation about its axis. The pumping means can include a piston within the reservoir moveable between an upper and lower position and a shaft having an internal tube connecting the piston to the manually operable means. The manually operable means moves in a reciprocal manner to reciprocate the shaft and piston forcing liquid from the reservoir into the tube on downward stroke of the piston. The liquid travels up the tube and is expressed onto the brush.
