Abstract: A golf club head brush (10) for cleaning a golf club head (38) comprises a relatively flat, generally-rectangular, handle (11) having opposite brush and non-brush sides (12,14) bounded by shaft, head, thumb and finger edges (26, 27, 18, 22), with brush bristles (28) mounted on the brush side directed outwardly away from the handle. The handle is constructed of a resilient material so as to be bendable. The brush and non-brush sides have the generally-rectangular shape, but include a thumb protrusion (16) at the thumb edge with bristles thereon. The shaft edge includes an outwardly flaring shaft slot (24) therein for receiving a shaft when the bristles are used to clean a golf club head.
