I don't understand this problem and why I don't have it. I no longer use L'Art du Son, but I have had a nearly full one gallon distilled water and L'Art du Son bottle sitting next to my Loricraft for over a year and have no mold. My Texas home does have central air and heat, of course, but mold does show up on food and other cultures in our house. I know that L'Art du Son does not contain any bleach given its goal to remove no vinyl when cleaning.
Is it possible that contaminated vessels or water were used in the first mixing?
