A spray cleaning apparatus discharges pressurized fluid through apertures or nozzles to clean debris and compacted grass clippings from an interior surface of a blade housing. The apparatus includes a hollow body defining a fluid passage with an inlet connectible to a source of fluid under pressure. At least one upwardly extending surface is provided for positioning the hollow body with respect to a wall of the blade housing such that at least a portion of the hollow body extends under the wall of the blade housing. An angled portion of an upper surface of the hollow body is positioned with respect to the at least one upwardly extending surface to expose the angled portion to an interior of the blade housing. A plurality of apertures extend through the angled portion for spraying pressurized fluid when the hollow body is connected to a source of pressurized fluid. The angled portion includes a self-centering concave surface with a curved leading edge. The angled portion transitions to a flat surface prior to the upwardly extending surface. The transition between the angled portion and the flat portion defines a curved transition line. The flat portion provides a landing for engagement with a bottom of the wall of the blade housing, when the wall of the blade housing is positioned against the upwardly extending surface of the deck-stop. The concave angled portion reduces the possibility of contact with the cleaning apparatus by the blades of the lawn mower during the cleaning process.
