Hmmm, well, I can't imagine vaping from a cartomizer that's been sitting in standing water for any length of time, especially if the excess water has only been blown out (or even spun out using an old sock or bag, which doesn't remove all the moisture, by the way), and the filler is still damp or soggy with that old water. I might be able to take a bath in old, standing water (as long as it's warm enough), but I sure wouldn't inhale it!
Sorry, but in my case, I'll only refill cartomizers that have been cleaned (using only clean, fresh water), flushed of all excess water, and dried completely and as quickly as possible (as in, using a fan, not just letting them air dry on a paper towel, which would take much longer and have more of a chance of mildew forming inside the carto).
Yea, I saw Shan's video and decided spending tons of time trying to loosen the threaded end of the carto from the casing was not for me. If there was a much quicker way to remove that part from the casing, I'd be interested. But time is money for me, especially during tax season, when I'll be too busy to even refill cartomizers -- or vape very often.
