1. A handle cleaning device comprising at least one handle comprising a gripping surface to be cleaned forming part of a tubular or partially tubular-shaped wall, an application member for applying a cleaning liquid on the gripping surface, and cleaning liquid supply means comprising at least one tank for receiving and distributing cleaning liquid to the application member, the application member being formed at least in part of an annular bushing mounted around the gripping surface and comprising at least one buffer reserve arranged in contact with the gripping surface, the device further comprising a unit for actuating the application member comprising driving means configured to move the application member by a magnetic coupling axially along said gripping surface between a distribution position for the transfer of cleaning liquid in the buffer reserve and an application configuration for the application of cleaning liquid on the gripping surface so as to apply cleaning liquid from the buffer reserve on the gripping surface during this displacement, the driving means comprising a worm screw extending longitudinally inside the tubular wall of the gripping surface of the handle and a nut movable along the worm screw, the nut driving a magnet which drives the bushing of the application member, said bushing comprising a magnetized or ferromagnetic body.
