I have never had an atty quit producing vapor. When vapor production goes down, it has always been a battery problem (in my experience, that is) Atty cleaning for me is to get rid of a bad, burnt juice taste. I have used Everclear, boiled distilled water, Coke,Crest Pro, and just plain blowing. I even tried simulating the jewelry cleaner thing by sitting a small jar of fluid and atties on top of a vibrating aquarium pump. Is one method better than any other? Not really. At least, not that I've seen.
Blucig atties never die. I clean them only to get rid of a juice flavor I didn't like. OK - one did die, but it was a violent death. I stepped on it. But I guess that would kill anything. LOL
My J118 atties never died. They always vaped well, and never tasted bad. The batteries have the lifespan of a fruit fly, though. So I gave up on that model. Too bad, because I really liked that one.
My new favorite PV is the RN4072 penstyle. Batteries last for hours, carts are easy to fill and hold tons of juice, and I just think they look cool

I have a problem with their atomizers though. They last me three weeks to the day! Vapor production is still great - these things are fog machines. It is the taste. On day 22 - they taste like the bottom of a used ashtray with a hint of burnt plastic. I do vape almost exclusively tobacco flavors, but none of them have THAT taste. I've tried cleaning them, but that only gets me one or two carts worth of vaping before the taste comes back.
Any ideas

or am I just stuck with replacing atties all the time?
Thanks,
