A cleaning solution for a turbine engine includes water; a first organic acidic component that comprises citric acid; a second organic acidic component that comprises glycolic acid; isopropylamine sulphonate; alcohol ethoxylate; triethanol amine; and sodium lauriminodipropionate. The cleaning solution has a pH value between about 2.5 and about 7.0.
Claims1
A cleaning solution for an in-situ aircraft turbine engine, the cleaning solution comprising:
- at least a first organic acidic component within a range between about 0.1 percent and about 15 percent of the cleaning solution;
- a surfactant within a range between about 0.07 percent and about 0.14 weight percent of the cleaning solution;
- alcohol ethoxylate within a range between about 0.035 percent and about 0.07 weight percent of the cleaning solution;
- monosodium-N-lauryl-B-iminodipropionic acid within a range between about 0.03 and about 1.0 percent volume of the cleaning solution;
- and
- an organic base that was added by weight to tritate the cleaning solution to a pH within a range of about 2.5 to about 7.0.
