PROBLEM TO BE SOLVED: To provide a method for removing niobium-rich second-phase-particles (SPP) deposits from zirconium-niobium alloy components. SOLUTION: The method comprises washing a freshly pickled and rinsed zirconium-niobium alloy component with an acidified oxalic acid or ammonium oxalate washing solution. The method of the present invention results in a rapid, efficient and complete removal of surface SPP deposits from the zirconium-niobium alloy component without pitting, leaving behind a clean, shinny surface without the need to use water blasting or mechanical wiping operation.
