Oh man... dual coil can last anywhere from... eh, say a week to two mos? lol I know that's not much of a guideline. I've had some that die quickly and some that are little energizer bunnies. And you lost me on the supernova thing.. guessing that's the name of the carto, but offhand, thinking that's new to me. Or maybe you mean the tank, I dunno. Either way, in my experience, cartos in tanks don't last quite as long as those out of tanks. As for cleaning, you certainly can, but I usually don't clean them till they start to get harder to hit, and there's flavor reduction going on. Keep in mind, cleaning a carto with filler takes a good day or two, just cause you have to wait for the filler to dry after you spin the excess water out (reverse taryn spin) post filling. I'm not a big fan of the dual coils (I actually use single coils in my dual coil tanks) so I don't have the best troubleshooting advice on those ones. LOTS of people love em, though, so hoping someone else has some bright ideas. I just did a quick search for 'vape, supernova' and came up with a whole lotta people vaping illicit substances. lol Clearly not gonna figure out what you've got there with a google search. rofl But it was funny, all the same.

Oh, wait.. could you mean Vivi Nova? Hummm... very possibly. If you do... I've not used those, but I know there are a ton of people talking about them and how to trouble shoot them in the Gotvapes forum, though. Man... fat lotta help I am, today, huh? rofl Anyway, lemme know specifically what you're talking about if its something other than straight smoktech brand dual coils, and I'll see what info I can hunt up re cleaning and halflives for ya.
And you know what.. just thought about something else.. again.. assuming you're dealing with a plain old 1.5ohm dual coil. I do this with my single coils, and it seems like would apply to dual coils as well, since they're also thick filler cartos. So lets say you've been vaping primarily that carto for a week or so. Sometimes, right when the flavor starts to get 'shallow' and lose its nuances, rather than taking the time to clean it, I'll just spin all the juice out of it till its as dry as I can get it... dump juice back in bottle, and then start fresh with a new fill up with taryn spin. Seems silly, but juice really doesn't like to sit around affected by heat for a week or more, plus it helps to make the carto less 'cloggy' feeling on the draw. That new spin fill really drives the juice down into the filler, and seems to fluff up the filler a bit in process. I do think that extends, maybe not my life, but the amount of time I want to vape a carto before setting it aside for future cleaning. Works for me, anyway.
