I have 3 atomizers for the 510 I'm using with an Ego. I have read to clean them regularly. I've tried alcohol baths and I've tried simply using hot water. Whatever I use, lately I've found that after they're clean, when I inhale it produces heated (not normal) thin vapor and almost immediately (second or third hit) tastes burnt. It's almost like I'm just sucking in hot air or steam if that makes sense? I would think it was a bad atomizer but this happens with all three. Oh - this happens when trying to direct drip (3-4 drops directly on atty). I've been able to get an atty back to normal once by filling a cart and vaping that way instead of dripping. After one cart full, I then started direct dripping and it was fine. I have been letting them dry overnight and blowing them out before trying to use them. Anyway, what am I doing wrong? Right now I have three unusable attys and no way to vape! Thanks - I hope my question was clear, it's kind of hard to describe what they are doing.
