By self cleaning you mean you just rinse the rayon when it's gunked up?
Cob said it really well. It's really pretty amazing to watch in a dripper! I change flavors a lot and you don't need to rewick with rayon. I've opened the magma and thought wow the rayon looks nasty. Went on and finished the remainder of the well and opened to rewick and wow it's completely clean. When you go to a different flavor just refill and go. A couple of puffs and there's no leftover flavor at all
