Distilled, de-ionized and treated by reverse osmosis waters should be interchangeable. Real distilled water may be more expensive due to the added energy cost in boiling it. It may be that "distilled" is used as a blanket term. In today's dumbed down society the average person probably doesn't known what de-ionized means.

I've made a point of using distilled water for many of my photographic uses. But I'm hearing more references lately to distilled AND deionized water. What are the advantages? And where might I be able to find it? I was just in the grocery store today (where I usually buy distilled water). I didn't find any bottle that claimed the water was deionised. I also noted that the store has replaced much (but not all) of its selection of distilled with reverse osmosis water! I'm guessing that it may get harder to find distilled water. --Ben ======================================================================== ===================================== To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there. ============================================================================================================To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
