Plating removal

An artist-type friend asked me how to get the plating off of bolt heads so that they will rust... It seems to me that a little hydrochloric acid would do it, but does anyone have any suggestions? The other way, of course, is to chuck them in the lathe and take a file to them...

The simplest way to remove zinc plating is a lye soak.

I'd go with the HCL Muratic will sure do the trick as we learned when Uncle acidized his well. Took the galvanized right off the piping.

Hey |Grant,

Oh, I dunno. To me, the SIMPLEST thing is to buy un-plated hardware to start with!.

That's the simplest THING. The simplest way to REMOVE ZINC COATING is a lye soak.

It's better than an acid soak because acid soaking can cause hydrogen embrittlement, also when you're done removing the bolts you can put some small rusty things into the zinc/lye and the zinc will remove the rust. Then it can go right down the sewer, because most groundwater runoff is slightly acidic, so any cleanish base helps out.

If you use "inhibited" or "killed" acid, it is already saturated with zinc and will not dissolve any more. This form is commonly used for de-scaling galvanized plumbing and is commonly available at pool supply places. It is also used for fluxing when soldering galvanized roofing.
