I just tried some of the e-power dual coil cartos and I love them. They hold boatloads of juice (over 5ml) and I can vape all day on them w/o a refill. That said, I'm dreading the day I want to clean them. I use the boil method generally, and I assume I can with these as well. But am I going to wait a week or more for them to dry out? Is there a better method?
