Abstract: A cleaning method for gas turbine engine airfoils includes a step of immersing an ultrasonic agitator, such as a welding horn, into a tank with a cleaning solution and a step of directing the ultrasonic agitator onto the portion of the airfoil having the crust layer. A subsequent step of high pressure water jet spray removes the crust debris. The cleaning method of the present invention significantly increases the power density of the ultrasonic cleaning.
