A method of removing surface dirt and contaminants from a component, such as a turbine, combustor or augmentor component of a gas turbine engine. The processing steps generally include soaking the component in a solution containing acetic acid, agitating the surfaces of the component such as with ultrasonic energy, and then rinsing the component of the acetic acid solution. A preferred acetic acid solution is vinegar either diluted by water or used full strength. Preferably, the component is also immersed in a solution containing acetic acid during the agitation step. The treatment steps can be performed at room temperature for durations of as little as two hours. The method is particularly suited for the removal of silica and calcium-containing compounds from air-cooled components protected with an environmental coating such as a diffusion aluminide coating.
