The polymeric 123-superconductor material was selectively etched by exposure to aqueous solutions of oxalic acid and disodium oxalate. Superconductivity decreased with time. XPS, AES, FTIR and ATF show that the amount of copper at the surface is decreased, shows the presence of bound oxalate and shows a decrease in peaks associated with superconductivity for the sample treated with oxalate
