I've never had a burnt wick no matter how much I've dry burned, and I dry burn like a muthu. If your'e having burnt taste after dry burning, and assuming the coil has liquid, you probably didn't get the coil clean enough. If you've used a high percentage VG
juice they often build up a burnt crust on the coil, if it's not all gotten off you will taste it. Sometimes you have to pick that stuff off then do a second rinse and burn. Another thing I've seen on some of the cleaning videos where the clearo is just rinsed and burned without being taken apart, as far as I'm concerned if you can't take it apart and see the full coil you can't really effectively clean it.
