Absolutely correct- D.I   water is as acid as Coca Cola. For a graphic 
demonstration, take some distilled water and put a scrap piece of aluminum in it. 
You'll likely see hydrogen bubbles coming off and the part will be severely 
corroded overnight! For a crude comparison test, you can do the same with your 
local tap water, and with soft water. It doesn't take long to figure out whats 
the best deal. FWIW- J Deryke
