Yambor44, Distilled will definately be better, especially with that length of storage time. If your pH is staying below three for that long, however, that tells me you're either using a softener or the minerals aren't that bad. If the cloudiness, though present from the beginning, doesn't get worse, then moving to distilled may well be uneccessary. In light of my earlier comments on other threads today, however, I can certainly appreciate those who want to err on the side of caution. Cheers!
