TBH, by what ive gathered, id agree with steve here, i havent 6v vaped, but everything on my 5v passthru .... is crap tbh, and burns even worse than than 3.7-4.2 or standard batt types.
I take it you mean clearomisers, I use them at home and generally use one per flavour as there cheap enough, and if i can get 2-3 days vape out of it (3 or so fills) im happy with that, i cant really be a$$ed to faff with cleaning tbh, as by this point the element is generally past it for me.
Actually, just read ya post again, my above stands for pretty much all carto's / clearo's, my work ones i just use for the shift, vape the last of it down on my last day of using it, so i dont waste 3ml a time, then chuck it.
Again, its not a "clean it" and it'll do another 3 or so days, an element wire itself can only do so much before it starts to drop off its best see.
For me personally, i dont think i'll ever 6v vape, ie get a provari etc, and tbh i'd only consider going down in voltage as most of the stuff ive ever vaped with burns my flavours, ive stopped with clearo's now and ego smok dual coil carto's.
So everythings factored into my monthly "guesstimate" of costs, that is to simply throw it away, for a quid or so's worth of carto / clearo it just aint worth the hassle of cleaning it, IMHO
vape on, lee
