So, clear me up on something. A dry burn is... well... dry. I use it on a fresh coil to sort of temper the coil -- which seems to reduce any initial metallic taste. When you dry burn a used wick, doesn't it just cook the residue in the coil down to charcoal? It's always been a guaranteed burnt flavor for me to do that, but maybe I need to try on some other juices. I pretty much gave it up after the first few times. I tried rinsing it then burning it repeatedly thinking that it might flush some of the old out while adding additional moisture to vaporize, but still no good...
