You may have to fill them 1 more time after you finish vaping off of this fill. I have had luck with most of my carto's especially my ce2r4's, but a small amount of boge's had a bit of a dry burn taste, but after a couple of fills they were good to go. Just glad you got to vaping again, would hate to see you have to go to the gas station for you know what!I tried cleaning the cartos out and I haven't had much luck. I boiled them for about 10 minutes and then let them dry a few hours, then ran really hot water through them, then put them in the oven on a very low setting to dry them out a bit. They work fine but taste horrid. Ah well, dems da breaks.
