I like to vape very dark & nasty juices for some reason, & I have discovered a couple things which have allowed me to double or triple the lifespan of most cartos. Many of you probably know similar tricks already but for those who don't:
1) Cover the bottom hole (battery side) of the carto completely, using your finger & a napkin if desired. Seal your mouth over the drip tip or open top end & blow as hard as you can into the carto. This will help to keep the air intake holes clear; they are very small so you will not get much air through there; blow until a little clean juice starts leaking out of the intake holes. When completed clean this juice away from the holes & threading.
2) Find a napkin, paper towel, or some toilet paper: tear off a small strip about an inch wide and a few inches long. Grip it between your fingers & twist it into a small string; it is important to "thread" it one way, like the way ropes are threaded. Thread this up the center hole of the carto, twisting it in the direction of string threading - it won't go completely through due to the heating element but the twisting & bending will help clean that off. When it is in as far as possible, continue to twist it in place & then remove. You will see sediment coating the string, especially at the tip.
3) Do these two things at least once a day, & every time you refill.
