Abstract: A method for determining the suitability for use in an engine of a fuel e.g. a jet fuel that may contain particulate contaminants, such as organic and/or inorganic particulates, is disclosed. The method can be used to distinguish a known organic particulate contaminant from inorganic particulate contaminants in the fuel. A composition suitable for use in the method is also disclosed.

Abstract: A method for in-situ cleaning of compressor blades in a gas turbine engine on an aircraft comprises the following sequential steps: Step 1—washing said compressor blades by spraying a first liquid composition into the engine; and Step 2—finally rinsing said washed compressor blades by spraying a second liquid composition into the engine, wherein the second liquid composition, has a freezing point of ?10° C. or below and is non-aqueous and hydrophilic.
