An engine wash manifold delivers wash liquid to an engine that includes an inlet, a fan, a case with an exhaust duct and a core inlet splitter. The manifold includes a wash delivery segment comprising a pipe shaped to follow at least in part engine case curvature with a first end to interface with the core inlet splitter and a second end with an inlet to receive wash fluid. The manifold further includes a retention system to secure the wash delivery segment to the engine and one or more nozzles on the first end of the wash delivery segment to spray wash fluid. The wash fluid may be atomized. The manifold further may include nozzles that deliver atomized wash liquid to the aft side of fan blades and may be used in conjunction with an inlet mounted manifold.
