A liquid applicator for cleaning a vehicle includes a frame in the form of an arch extending over a path of the vehicle to be washed. Spray pipes are rotatably connected to the sides and top of the arch with the spray pipes being connected by flexible hoses which transmit oscillating rotary movement from one pipe to the other connected pipes. A motor is provided to transmit oscillating rotating movement to one of the spray pipes and cause all of the spray pipes to rotatingly oscillate.
