Abstract: A system for spray-washing salt and the like from the underside of a motor vehicle has a hollow handle for connection to a garden hose at a first end and to upward spray nozzles on wheels covered by a body or housing with anti-snag shape, at a second end. Steering the spray nozzles to spray in a desired direction within a wide arc requires only twisting the handle in the direction desired. A flexible portion of the handle or alternatively a flexible handle provides this advantage. A detergent or liquid soap container is fixed upright on the handle in position for preventing a user's hand from striking a vehicle being washed on the underside. The handle and the spray may be detached and used apart from the body for hand-held applications.
