Would Oxi be something I could use to remove hard water stains on a metal fence? A customer has about 150' of fence that needs to be cleaned.

I doubt OxiWash will remove those hard water stains. You will need a product like F9, but I would do a small test spot to make sure you do not change the color of the painted metal or rip it off.
