Solvent-based gas turbine compressor cleaner is intended for both on and off line wet cleaning applications. It is specifically formulated from organic solvents, surfactants and emulsifiers designed to remove grease, oil, soot and other deposits commonly find in gas turbine compressors. For on line cleaning the diluted fluid is injected into the compressor section of the turbine while the unit is in operation. Average power loss is reduced and periodic off line cleaning intervals can be extended. For off line cleaning using typical soak and rinse procedures, is used at the same dilution strength and power recovery is normally significant.
