Can you use a vibrating parts tumbler to remove the hot dipped

Probably, if you have an abrasive in there that can do the business. Would guess that the areas inside the links would get poor coverage, depending on the granule size

Thanks. Is sand enough or do I need something more aggressive? I've seen people use like ground walnut shells or something but that seems too soft.

sand would probably work Eventually? You would be turning sand into finer sand at almost the same rate.

You would probably want something like an aluminum oxide grit or silicon dioxide.

Another option would be to strip off the zinc in a water and acid, Muriatic Acid probably. Experiment a bit for the proper ratio and time, always add acid to water, not water to acid if you are thinning it down, and some chemical protective gloves and face shield is a good idea.

Rinse in a large amount of water and/or neutralize with water+baking soda. Then you will want to get that stuff dry and oiled as fast as possible because it will want to rust into a lump immediately.

(dont keep acid in the house, dispose of by diluting by large factors, etc, etc)

yeah hydrochloric acid is a much better option for a steel chain

>dont keep acid in the house
as long as you really seal it it's ok
...if you dont by the tiniest amount the fumes will corrode/rust any metal you have in the room.

it is zinc so just hook it up to some electrode in solution and electrolysis its ass off.

Vinegar will also work well. Just toss in some pennies with it.

That's a damn good idea. Not 100% about the procedure though, I'm guessing submerging the chain in a plastic tub filled with washing soda, hooking up the positive lead from a battery charger to the chain and the negative lead to a sacrificial scrap piece of iron?

Not OP but I have a related question.

I want to remove the galvanization from a chain mail shirt I'm working on and then build up a black oxide layer instead. What's the best way to do this?

Why not just burn off the zinc? Just don't breath in the fumes.
