Distilled water, is not healthy, good for adding to battery's (best) or for anyone that still iron their clothes. Nutter name is deionized water (ions=minerals) which is also used in washing electronic ckt boards to remove flux and crap.
Jerry I agree, one time here the tap water was world class, not anymore, with the chlorine and or chloramine additive. At least chlorine can gas out, been fighting chloramine in the water to make my sourdough, gave up and now use bottled water in 5 gal jugs. (also drink it) Tap water here is only maybe good for showers, but not drinking, sad to say today from how good it was in the past.
Distilled water = Blah , no taste, and good water has a taste, which is the minerals in it to make that taste.
Cleaning electronic boards, filler for battery's or any steam cleaning or pressing of clothes , but not drinking.
In my not so humble opinion.
Edit: Water is in its own class as being corrosive, ask any rock or other mineral, natural or man made...
Hoot!
