Distilled water has no minerals of any kind, therefore, it's good for cleaning and batteries without having to worry about it leaving behind minerals (lime, calcium, etc) when it evaporates. It's not, however, good for drinking. Since there are no more minerals in it, it's no longer healthy for you.
Regular water has different minerals in chemicals in it, though. Good for drinking and excellent at quenching thirst. :)
Distilled water has been boiled and the steam (water vaper) is collected, then bottled this get rid of well everything but Pure H2O.Is flavored water the same as regular water?
