Abstract : The patent describes aqueous compositions which contain, by weight, 2.25 to 2.75% of tetrasodium ethylenediamine tetraacetate dihydrate, 9 to 11% of sodium nitrite, 9 to 11% of a water soluble nonionic surfactant, for example, a poloxyethylene-polyoxypropylene alcohol, 4.5 to 5.5% of sodium benzoate, 33 to 39% of water, 14 to 18% of isopropanol and 14 to 23% of methanol. The compositions when diluted with water provide washing solutions which are effective to quickly flush salt water spray residues from compressor surfaces in gas turbine engines of carrier based aircraft.
