Hi all, in the process of doing a weekly cleaning on my T-atomizer, I've been using it for 1 week and started to notice a slight decrease in performance. I boiled some distilled water and flushed it out a few times until the water flowed freely and clear. I'm doing a dry burn of 5 sec on/5 off about 5 times now but no glowing or smoke, does this mean it's all set to go or should I be dry burning until I see a red glow?
