Ok, so I'm reading this and I didn't see the big ones. First off, what kinda wick and arty. Genesis with Ss cable or wire mesh hold flavor longer but can be simply rinsed. Cotton holds flavor but if they are similar or complimentary, vape through. If not, simply change the cotton. (its the reason I use coils that the wick can easily be changed... Anything micro/nano coil) If you are using a dripping atty and sillica, light the thing on fire with a lighter. It burns off all flavor and after it cools go for it.
