Abstract
Gas turbine compressors are cleaned during power generation (on line) by periodically injecting or spraying into the air inlet, a cleaning composition comprising 4-95 percent by weight of a glycol ether such as ethylene glycol butyl ether, or a mixture of glycol ethers such as propylene glycol methyl ether and dipropylene glycol methyl ether, 0.1 to 14 percent by weight of a nonionic surfactant, 0.01 to 6 percent by weight of a cationic surfactant and 0 to 95 percent by weight of water.
