Abstract: A tool is disclosed that facilitates use of a vehicle wash mitt of the type having an interior of predetermined size for receiving a human hand. The tool is referred to as a truck wash paddle assembly for use in washing difficult-to-reach portions of the user's pickup truck or other vehicle. It includes an object referred to as a mitt-holding member (i.e., an MHM) on which a user mounts an elongated handle to form the tool. The MHM includes a body of material having a size and shape that fits within the interior of the wash mitt in the place of the human hand. A handle-receiving portion of the MHM defines a handle-receiving bore for receiving the end portion of an elongated handle. Preferably, an interiorly threaded metal insert within the bore mates with the exteriorly threaded end portion of a commonly available handle having an Acme-type thread. Simply removing the wash mitt from the MHM readies it for independent use, cleaning, and storage.
