I always clean and dry burn my EVOD's and T3's after each fill. I have a lot of them so once ive used about 8, i throw them all into a bowl, turn on the hot water in my sink, and leave the hot water running into the bowl for about 15 mins. Then I dry off the wicks with paper towel, remove the center post and extra wicks from the head, then dry burn the coil. Am I doing it too often? Is my method wrong? Anyone have any better suggestions?
