  • Patent number: 4225996
    Abstract: A scouring pad is placed between two parallel rotating rollers mounted in a slot formed in the top of a platform. The lower surfaces of the rollers are wetted by a liquid detergent solution contained in a tank mounted below the platform. A shoe roller skate having a front pair and a rear pair of wheels is placed on the platform with one pair of wheels resting on the rollers and engaging the top of the scouring pad. The rollers rotate the skate wheels against the scouring pad, thereby removing dirt from the skate wheels by an abrading action. The liquid detergent is transferred from the rollers to the skate wheels and scouring pad, thereby enhancing the removal of the dirt from the skate wheels.
