Been using mini tanks about 3 weeks now, have 4 of them and wash them out in hot water after about 4 uses each, let them dry 24 hours and then use them again. I noticed that after each wash the draw on them was tighter and tighter, requiring a harder and longer draw to get as much vapor and taste then when they were new. So I followed some suggestions I saw here and using a G6 manual battery dry burned them after letting them dry for about 6-7 seconds, doing that twice for each tank and now they seem as good as new, with a much easier draw. I had been afraid to do that, thinking I'd burn out the coils (or burn the wicks) by dry burning, but I am definitely going to do that after each washing now. All 4 tanks seem just fine after about 3 weeks so I don't know how long they will last, but they seem quite durable.
With each dry burn, even after allowing them to dry for well over 24 hours, I see vapor coming off the wicks so they must not be completely dry even after 2 days (in one case) or I am burning off old juice that just won't rinse out. Either way it seems dry burning is a must for mini tanks.
