How to remove acid from zinc in plating
January 5, 2009
Hi, we have a jewelry plating factory in Mexico and the items are coming out with bubbles and grayish color. How can I remove the acid from the zinc?

Huh? Sorry, Aaron, I don't understand the question. Are you implying that the jewelry is a zinc die casting, and you believe that the porosity in the diecastings is holding acid and causing these problems?
I think that it is possible, but your question is vague. Please spend a few paragraphs describing your situation. Thanks.
