Washing apparatus for cleaning the lenses of goggles, worn by a motorcyclist during a muddy race, is mounted on the forward portion of a duck bill visor to jet spray cleaning liquid onto the goggles to clear the lenses of mud. An oval tank of cleaning liquid is pressurized with air and supported on the front fork of the cycle, there being a flexible tube extending from the tank, up the sleeve of the rider and thence along the helmet to the jet spray on the visor. A finger actuated control valve and a breakaway are incorporated into the tube.
