The present application and the resultant patent provide a wash system for a gas turbine engine. The wash system may include a water source containing a volume of water therein, and a surface filming agent source containing a volume of a surface filming agent therein. The wash system also may include a mixing chamber in fluid communication with the water source and the surface filming agent source, wherein the mixing chamber is configured to mix the water and the surface filming agent therein to produce a film-forming mixture. The wash system further may include an aerosolizing device in fluid communication with the mixing chamber and configured to form an aerosol spray of the film-forming mixture and a propellant. The wash system still further may include a number of supply lines in fluid communication with the aerosolizing device and configured to direct the aerosol spray into the gas turbine engine.
