Hi,

From an earlier thread:

"Distilled water is evaporated to steam and then condensed again and therefore should have no minerals or dissolved materials in it, but unless also filtered it could have a little dust in it.

Demineralised water is passed through a series of resins which remove dissolved materials, and then a membrane which filters out solids, even down to bacteria depending on the standard used.

I don't believe there is any effective difference for mirror rinsing"

So - I believe Starkler is quite right.

Cheers
