Beschreibung
Zusammenfassung:	A method of cleaning a component includes providing the component following the operation of the component in a high temperature environment, the component including a thermal barrier coating (TBC), cleaning the TBC of the component using a sponge jet blasting process, and measuring a cleaned thickness of the TBC to verify that the cleaned thickness exceeds a predetermined minimum value that will allow the return of the component to the high temperature environment.
