Looking up what else works, I see there is some discussion as

Apparently Hydrochloric acid + iron yields iron chloride.

But, if you don't wash all the iron chloride out, water + iron chloride
in a warm environment will regenerate iron oxide (rust) + HCl.


I screwed up when I left the lid off a container of HCl setting on my
shop bench. Two days later when I went back in the shop the fumes had
caused every iron tool hanging on the pegboard to have a film of rust
similar to your toolbox. HCl never comes inside any more.
