Introduction to Copper Nickel Piping and Applications
COPPER NICKEL PIPING. The corrosion resistance of CuNi alloys is due to the presence of protective surface film of copper nickel oxide which is firmly bonded to the metal and which is almost insoluble in water. This oxide film protects the piping from further attack. The protective oxide film takes about three months to stabilize.

This is a bit more complicated than dip and rinse, but if you have a lot to strip, maybe you can make it work. Nickel is mined, going from the oxide to the metal, by reacting the ore with water gas, a mixture of H 2 and CO (made by adding H 2 O to hot and/or burning coal - at the relatively low temperature of 50ºC and atmospheric pressure). Now the OP …
