Abstract: A cleaning solution for a turbine engine includes water within a range between about 68.65 percent and about 99.63 percent by volume of the cleaning solution; a first organic acidic component within a range between about 0.1 percent and about 15 percent by volume of the cleaning solution; wherein the organic acid comprises citric acid; a second organic acidic component within a range between about 0.1 percent and about 15 percent by volume of the cleaning solution; wherein the organic acid comprises glycolic acid; isoropylamine sulphonate within a range between about 0.07 percent and 0.14 percent by volume of the cleaning solution; alcohol ethoxylate within a range between about 0.035 percent and 0.07 percent by volume of the cleaning solution; triethanol amine within a range between about 0.035 percent and 0.07 percent by volume of the cleaning solution; sodium lauriminodipropionate within a range between about 0.03 percent and 1.0 percent by volume of the cleaning solution. The cleaning solution has a pH value in the range between about 2.5 and about 7.0.

Abstract: A cleaning solution for a turbine engine includes a reagent composition including 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, and an amine component within a range between about 1 percent and 40 percent by volume of the reagent composition. The reagent composition is diluted with water by a factor of up to about 40 to form the cleaning solution. The cleaning solution has a pH value in the range between 2.5 and 7.0. The cleaning solution is directed towards a component of the turbine engine having a layer of foreign material thereon, to at least partially remove the foreign material from the component. The layer of foreign material is formed at least partially from at least one of thermal reaction products of the foreign material and interstitial cement.
