That's why it's called distilled water.
and that's why it's called deionized water.
Distillation is the process in which water is boiled and the steam is then condensed into a clean container.
Deionization is more complex (and expensive). This is a chemical process that involves the use of ion exchange resins (hence the expensive part).
But none of this stuff is really relevant here.
MY advice to anyone is to experiment with plain water in your area.
Personally, I just stick to the manufacturers products that are specifically designed to work with their products.
But that's just me.
