Isn't the water used in the premixed solutions for sale already distilled, uncontaminated, or neutral ph water? I thought I read somewhere that it was, but I could be wrong. Prestone's web site says their 50/50 premix uses demineralized water, and I might suspect that most major brand use that as well.
Got your email about the pending move. Hope to see you when we next visit San Diego.
