interesting. I had about 50 cartos that I would use, set aside uncovered, then refil, repeat.. after a few cycles, wash, fill, repeat.
this went on for about 6 months. all of them left for long periods of time. they all worked fine, but eventually clogged enough that I just opted to buy new ones.
point being, I don't know why the atty inside the carto would just "pop", and stop working, just because it was left, wet or dry.
I guess i'd have to agree, YMMV.
I don't know how long e-
juice would take to evaporate. I mean, everything will eventually, right? but I don't think a few days or even weeks would ever hurt anything. not a real scientific approach to the subject matter, I know. but anyway, good luck!
