youll learn that a few flavors seem to "stick" in a
tank - menthol/mint for instance. you can get most of that flavor out with a rinse in vodka or mouthwash, i keep mine in "families" - usually one
tank is menthols, another is tobacco, another is fruity flavors, and one more for chocolate.. coffee mix goes in the choco-tank, etc..
even if you arent a fan of colored
tanks, it does minimize accidental surprise mixes..
that said, I got three-weeks out of my first clearo, simply by rinsing it out between flavors with cheap vodka.
if you have a tank that disassembles & has replaceable coils, you can do a pretty thorugh cleanout with just hot water..
