Iron water - never heard of it - what is it, and where can it be purchased.

Distilled water and from the chemist. Washing soda is used to soften water
but whether that is suitable for your purpose, I don't know.
"Washing soda is sodium carbonate.
Adding sodium carbonate to hard water
will precipitate insoluble calcium carbonate or magnesium carbonate.
This is a way of removing permanent hardness from water."
