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 for supplying 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, and
a unit for actuating the application member comprising driving means configured to move the application member 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,
wherein the buffer reserve comprises an applicator pad in contact with the gripping surface having a porous structure or a liquid retention interstice structure for storing some said cleaning liquid and wherein the cleaning liquid supply means comprises a cleaning liquid distribution manifold comprising at least one liquid outlet facing the applicator pad in the distribution position.
