The invention is a process for removing oxides, dirt, and organic impurities during repair of airfoils without damaging or effecting surface bond coats or base metal substrates of the airfoils. The process is especially suited for cleaning deep, tortuous cracks in the airfoils prior to brazing or alloying repair operations. The process entails using an autoclave with an organic caustic solution to fully remove the unwanted oxides, dirt, and organic impurities.
