More on this topic: not all "purified" water is created equal. I've seen steam-distilled
water and de-ionized water for sale as "purified" water, as well as purified drinking
water (usually de-ionized, with minerals added for flavor). You have to look on the
label to find out what you're getting.

Be careful with DI water; it is quite corrosive to many metals. Back in my youth,
I spent a summer working at an electronic assembly shop where PCB assemblies
were water-washed after wave-soldering to remove the (water-soluble) flux, and
finished with literally a dip in a DI water bath. One day, 10 or 15 boards were left
soaking in the DI water by accident during lunch; an hour later, the tin-plating
on the copper traces had been substantially removed by the DI water, leaving
most of the copper exposed.

Distilled water may not be healthy for a print head; DI water is certainly harmful.
