Glad you commented on that...

I was under that impression as well...and couldn't understand where everyone was getting the idea that distilled water was pH balanced???

Of course it's acidic it has no buffering minerals in it!

In fact, distilled water is considered a corrosive agent:

"Distilled water is nonconductive but is still corrosive; water is said to be the universal solvent However, no water is pure H2O, as it reacts with itself, forming hydroxide and hydronium ions. Hydroxide ions are the caustic component of lye, and hydronium ions make water corrosive. De Ionized Water (DI water) is neither corrosive nor conductive, but it will become so over time through this process."

"Distilled water may contain VOCs (volatile organic compounds), which are frequently removed with a carbon filter."

"Distilling water removes nearly all impurities from water, whether biological, mineral, or chemical. In itself it does not remove 100% of VOCs like benzene and toluene whose boiling points are near that of water, but it will remove calcium, magnesium, lead, viruses, bacteria, and protozoan cysts. In fact distilling water removes metals and oxygen, which results in the "flat" taste of distilled water."
