I believe I answered this poorly in your other thread, sorry about that, I was in a hurry.
What I was trying to say was that it's not as big a deal as it seems. When you start noticing a loss of flavor or vapor, check the cartridge. Push the filler down with tweezers to see if you can bring any remaining liquid to the top of the filler. If not, change the cartridge. (If you had liquid, this when you would normally refill.)
You don't necessarily need to keep the atty wet all the time, just try to avoid
vaping when it is dry. That is what could damage the atty, and the loss of flavor/vapor is your warning sign.
There are a lot of threads around here about different ways of cleaning, and how to store them, and a million other subjects. But I think most vets would agree that we really don't do that stuff all that much. Blow it out when it's flooded or hard to draw, and add
juice when it's dry. That's pretty much it most of the time. If it stops working altogether, THAT's when you read about cleaning, etc.
