What you are thinking of, as far as builders merchants are concerned, is Spirits of Salts, diluted it's good for quenching model boilers after silver soldering, as for ageing guitar parts I would think you'd have to be quite careful you didn't over do it.
At one Builders merchant I worked at in the 70's, long before health and safety, our cleaner used to liberally use it to clean the Gent's toilets, remember all those urinal stools in a line with ribbed floor tiles? if you were the first to pee in the trough after he'd been round it almost gassed you and your shoes would smoke as you stood there.
There was also Killed Spirits which I think was just about the same but the edge had been taken off by submersing zinc in the mix prior to bottling. that would probably be gentler.
The only question I have is WHY?
