1. A cleaning solution for a turbine engine, said cleaning solution comprising:
a reagent composition comprising:
water within a range between about 25 percent and about 70 percent by volume of the reagent composition;an acidic component within a range between about 0.1 percent and about 50 percent by volume of the reagent composition;an amine compound within a range between about 1 percent and 40 percent by volume of the reagent composition, wherein said reagent composition is diluted with water by a factor of up to about 40, thereby forming said cleaning solution; anda surfactant within a range between about 1 percent and about 7 percent by volume of the reagent composition, wherein the surfactant is an amine reacted with acrylic acid, the cleaning solution has a pH value in the range between 2.5 and 7.0, the cleaning solution is used to clean a component of the turbine engine, said reagent composition is configured to selectively dissolve at least one of oxide-based, chloride-based, sulfate-based, and carbon-based constituents of a foreign material, and said reagent composition is substantially unreactive with metallic materials and with a non-metallic material selected from the group consisting of rare earth element ceramic oxides, ceramic matrix composites and polymeric matrix composites. |
