My vapor-cherry popped in mid March of this year, and I gots to comment on cartomizers. I use one for a few days, then when the draw gets too stiff I chuck it into a jar. Once I have a good size stash I soak em all in vodka for a full 24 hours, or longer if I forget. Blow them out reaaeaaaally good, then let them dry for another full day or so. They gotta be bone-dry though before using them. Any grain alcohol will do, but it has to be grain alcohol. Cheap vodka is a good choice, as it won't leave stuff on the coil, which is very bad. I am still using 6 catomizers that have been cleaned this way twice already, and as long as one doesnt crank them down too hard, thus pushing the connection extension (scratches record) up into the carto, you're good to go. Atty's are real simple, just blow on them through the mouth-end into a paper towel or whatever every day, but you could also soak them in vodka.
