A water wash system (200) for a gas turbine engine (100) having a fan (126) and a front hub (136), the front hub (136) can be rotated with the fan (126). The water wash system (200) generally includes a head unit (202) and a base assembly (204). The head unit (202) includes a mounting structure (206) and one or more wash fluid lines (208) for spraying a wash fluid into the gas turbine engine (100). The mounting structure (206) defines an inner friction surface (252) for contacting the front hub (136) of the gas turbine engine (100). Additionally, the base assembly (204) is operatively connected to the head unit (202) and is configured to press the head unit (202) towards the front hub (136) to fix the inner friction surface (252) against the front hub (136).

Systems and methods for treating a component of an installed and assembled gas turbine engine are provided. Accordingly, the method includes operably coupling a delivery assembly to an annular inlet of a core gas turbine engine. A portion of treating fluid is atomized with the delivery assembly to develop a treating mist having a plurality of atomized droplets. The atomized droplets are suspended within any path of the core gas turbine engine from the annular inlet to an axial position downstream of a compressor of the core gas turbine engine. A portion of the treating mist is impacted or precipitated onto the component so as to wet the component, and a portion of the deposits on the component is dissolved by the treating mist.
