    With muriatic acid, very quickly. With citric acid, much more safely, but much more slowly.

            I use citric acid to remove the gold dichromate from modern grade 8 fasteners. After the dichromate is removed, changing the solution and letting the items soak longer should remove the zinc. What’s nice about citric acid is that you can get it on your skin without worry. Do not try that with muriatic acid, which is another name for hydrochloric acid.

                The small amount of muriatic acid you would need to accomplish this task can be tossed in your swimming pool when finished.

                    Looks like it. I will try the vinegar and baking soda route mentioned in the following thread below.
