If you've every vaped Wintergreen or Teaberry, vodka or another strong alcohol is about the only thing that'll get it out. Most all of my tanks are now stainless steel, so I boil most of them, but even that doesn't get those two flavors out. Once they're in, they're in until you give them a nice soak
It doesn't help that my first Teaberry DIY was running at about 10-15% flavor (which is a HORRIBLE overkill - that stuff is strong!).
