Rusting Bolts

I don't know what went on and don't really care.

The easiest way to remove the plating on most nuts and bolts is to use a propane torch. As you heat the bolt you'll see the plating oxidize away. Then salt water or vinegar for a while and the bolt will be nicely rusted.

Use the right tool for the job.

Zinc fumes are really bad for you. If you must do this, do it outside and down wind. Better to buy rustic hardware from a specialty supplier.

Muiratic acid will take care of the zinc plating and also induce rust. Just take the usual precautions when handling acid.

Hadn't thought of that. It wouldn't take much more than a few seconds to eat away the zinc and a r

It wouldn't take much more than a few seconds to eat away the zinc and a rinse in water to remove the remaining acid. Then in a week the bolts will be nicely rusted.
