"My still is stainless.  I can produce water as low as 0.4 PPM and typically

stainless does not release much into distilled water. DW is very aggressive 
compared with water with even a small amount of solute."

James, are you saying that pure water attacks stainless (we are talking kitchen 
cookware), and significantly more so than "dirty" water?
