This is wrong copper is the correct answer. As long as the residue doesn't affect the operational capabilities of the unit then it is to be left alone.

IAW CDC 2A652 vol 1 pg 5-3, copper is the one exception, because as long as it is doing its function, patina (green particles) actually forms a protective coating around the copper surface, and actually stops corrosion.
