I'm no expert in this field (or any for that matter) still,
as I understand it distilled water is sometimes called "hungry water"
because it's "empty" and will grab stuff such as metals. I thought
that distilled water would be great to use in ionic foot baths,
but turns out that it would be too damaging to the metal in the unit.
I finally got one this week and maybe it's just psychological, but I really
do feel cleaner, lighter afterwards.
