A device or system for cleaning windshields, headlamp lenses, rear view mirrors, reflector means, or the like of a vehicle. The system is installed in the vehicle, preferably in the engine compartment, and includes a liquid container, a conduit from the container to a steam generator, including a pump and a stop valve downstream of the pump to prevent return flow of liquid from the steam generator to the container. Engine exhaust heat or an electric heater is used for heating the steam generator, and an outlet conduit with nozzles direct steam from the generator to the vehicle parts to be cleaned. The system has a shunt conduit from the liquid supply bypassing the steam generator and connected to the outlet conduit downstream of the steam generator and steam from the generator mixes with the liquid from the shunt conduit and the mixture advances and flows out to the vehicle part or parts to be cleaned. The shunt line can be passed through a heat accumulator or exchanger to transfer engine exhaust heat to the shunted liquid. If desired, auxiliary cleaning lines can be tapped off of the shunt line to provide hot cleaning liquid not mixed with steam for selected parts of the vehicle.
