ABSTRACT:
A process is provided for cleaning residue fuel varnish and carbon from the fuel nozzles and guide vanes of a jet engine. The process involves dispensing a detergent and water solution under sufficient pressure through the fuel nozzles themselves to scrub residue fuel varnish and carbon from the fuel nozzles and from the guide vanes of a jet engine of an aircraft; without the need for removing the engine from the aircraft, or for removing the nozzles from the engine. The process serves to wet down the surfaces of the fuel nozzles and guide vanes with a detergent solution for a period of time (that is about 20 minutes), and then to scour the surfaces with a pulsating detergent spray, and finally to purge and dry the surfaces with a pressurized air stream.
