摘要： A method for removing a metallic material from the surface of a casted substrate includes the step of contacting the metallic material with an aqueous composition which comprises an acid having the formula H x AF 6 , or precursors to said acid. "A" in the formula is selected from the group consisting of Si, Ge, Ti, Zr, Al, and Ga; and x is 1-6.
