Having read all this - I wonder if pool accid (muriatic acid,

HCl is just going to cause rust. I use muriatic to dissolve
galvanizing (for welding), and all of the ferrous objects near the
bottle end up getting very rusty.

Jon I have found that to be true also. Used muriatic acid in my shop to
remove some alkali from an item and the fumes rusted all the tools nearby..
