  • Patent number: 5809606
    Abstract: A wheel cleaning cover, such as for a golf trolley wheel, is formed of a pair of hinged circular covers, each forming a semi-circular half and made of a light, robust material. When the golf trolley is not in use, a pair of such wheel covers can be closed around respective ones of the golf trolley's wheels. For each such wheel, the hinged semi-circular halves are securely fastened to one another to encase the associated wheel therewithin. The trolley wheels can remain on their axle(s) while the covers are securely closed around the wheels. When a cover is closed around its associated wheel and secured, it can be rotated and a brush installed in the cover functions as a cleaner/buffer, removing any mud, dirt, or grass on the enclosed wheel's surface. Debris from the wheel is contained within the cover until the cover is removed from the wheel, then any debris may be discarded.
