Copper Plating Removal: Simple, Effective Visual Check

Summary for copper plating removal Discussion

Copper plating removal from Cr-Co steel is discussed briefly, with Graeme Rolfe asking for a quick way to confirm that all copper has been removed from a 10% Cr, 6% Co steel surface. The only answer in the thread comes from an unnamed contributor who says, “I have always found the Mk1 eyeball to be very effective,” implying that careful visual inspection is the practical check. No chemical test, instrument method, or deeper procedure is offered in the excerpt, so the discussion is limited and informal. The takeaway is that, in this thread, the suggested method for verifying complete copper removal is straightforward visual examination rather than a more elaborate test.
