Jerms... I see a lot of people posting things like... "this atomizer has lasted me 3 months" and the like and... the thing is... "Great, now what juice were you vaping? If you were vaping coffee juice... might not last you 3 days, or even 3 hours.".
Also, people that have bridged 510s... cleaning them in PGA or whatever along those lines... sheesh... after you are done cleaning, you can HOPE they are cleaned but you can't see the coils so you don't really know what you got in there.
I don't have access to PGA but pretty much tried EVERYTHING to clean off the scabs and... almost no luck at all.
What is clogging up atties... is the FLAVORING... and it's a matter of not all the flavoring in some juices... vaporizing.
With the 306es and using 10x magnification... I can see in no uncertain terms what is going on there... and first you get a film over the coil and after that ultimately that film builds up... to the point where it forms... yeah, a SCAB. That is what it looks like and I have seen some, lol, this before I realized what was going on.... that were REALLY bad... couldn't even see the form of a coil underneath... were some really ugly suckers... and.. yeah, I popped a couple of these and then realized that... the scab forms and then the heat can't escape and that burns out the coil.
On the one's that had gotten badly scabbed... yeah... that is what I learned as well (not sure how you picked off the scabs on a 510). If you keep dry burning you will burn out the atty. But, what you do, is dry burn for a short time and then pick off the scab (what, with your fingernails... NOT), with a straight pin and then you can continue dry burning. With the heat now being able to escape... you won't burn out the attie.
Hmmm... can't remember if I ever tried my fingernails (lol). Might indeed try that next time around... but now I am usually cleaning my atties before they get big scabs.
