So its just the juice then?
I've been removing wick, washing the juice, dry burning (have to get it wile hot to cook it off, nearly white) then air cooling, brushing off the dust with a toothbrush, repeating a couple of times, re wicking, then an 8min session in the ultrasonic with some milton to get rid of that "new cotton" taste then ready to go again.
Shame its just gonna have to be that way, at least the wire is lasting well just the wicks when i remove mostly still look mint, wish i didnt have to bin them (not enough to pull through easily once theyve been trimmed to fit)
Might do a re coil soon, get some ni200 clapton made up and try it, might do spaced see if that makes a difference.
If you blow hard on the coil, the white flakes should just blow off, coils heat up red not white, when I do see white, it's normally a layer of ash.
I have never needed to use a brush to clean the coil, using miltons will mess up your o rings over long term. That new cotton taste is just down to the cotton you are using, I can't taste it with the stuff I use, unless I over wick.
