"Removing electroless Ni from steel"



1999

I am trying to remove electroless Nickel coating and Copper strike from steel without corroding steel surface. So far my results are very inconsistent: parts cleaned in the same acid vat never look the same. My acid bath is basically Hydrochloric/Sulfuric acids at 1 to 3 ratio with some surfactants and wetting agents. What am I missing in this process?

Thank you in advance,
Nina
