Love dry burning as part of cleaning my vivi novas. And I'll do it on any bridgeless atty or rebuildable I use in the future.
A short (like 2 minutes) alcohol soak, dry the wick, dry burn, repeat once……awesomely clean. The only problem
that I have run into with this equipment is that stupid thing in the vivi nova heads that redundantly insulates the coil from the body of the head scorches like that's it's job and tastes like crud. After taking it out and dry burning, the head I'm using on my mini is working just like it did when it first broke in……like 2 weeks ago. This morning my basically clear, yellow-tinged
juice was brown from all the gunk that had collected on it from the last time I cleaned it.
I'm a fan.
And if you over-burn, it seems like 2 bad things can happen: you wear out your coil and its resistance drops, making it more likely to run into a current limit on a VV or burn
juice on a non-VV……or you wear it out all at once and pop the coil.
