How to remove acid from zinc in plating

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?
Thank you.

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.

Regards,

DEAR SIR, I JUST TO HELP YOUR PROBLEM IN ACID ZINC PLATING AS FAMILIAR TO ME AND I SHOULD ENCOUNTERED THESE BEFORE. ANYWAY I'm A TECHNICIAN IN ANY KIND OF PLATING,THE BEST THING YOU TO DO IS JUST ONLY PUT 5g PER LITER ACTIVATED CARBON AND 5g PER LITTER zinc dust [on eBay or Amazon] .THEN YOU FILTER IN AND OUT AND BE SURE THAT THE BATH WAS TOTALLY CLEAN.AFTER THAT YOU PUT BRIGHTER BASE ON THE SUPPLIER REQUIREMENT.
