  • Patent number: 5081735
    Abstract: A golf iron cleaner particularly adapted to clean all golf irons, regardless of the loft, equally well. The present invention provides a golf iron cleaner that includes a container in which brushes are removably mounted. There are two brushes in each container and the bristles of each brush project inwardly toward each other. While the brushes face each other, the bristles do not touch, thus creating a channel between the bristles of the two brushes. The bristles of the two brushes are of a length so that the channel gives an appearance of a smooth curve, and as one progresses along the curve of the channel, the curve tends to mirror the loft of a golf iron as the loft is increased through the range of irons in a set. The bristles of one of the brushes are of a greater diameter and are thus stiffer than the bristles of the other brush. The container is positioned within a housing and can be removed from the housing to dispose of waste materials and to remove the brushes and cleanse them.
