How is this best performed? I have about a half dozen Kanger EVOD tanks and rotate through them so the coils should last a while. Would like to refresh them between juice changes.
Some people wash them in water, soak them in everclear or vodka and rewash them with water.
I've been doing my way for about 9 months and it works for me:
I have about 15 coils and 9 evods in rotation. I wash them when I've used about 5 or more.
I rinse/shake-out/rinse/shake-out (about 5-8x) the tanks and caps thoroughly in warm/hot water, shake and blow them out and set them in a butterdish overnight.
I rinse the coils in hot water, blow through, rinse again and throw them all in a small waterglass.
I direct the faucet at it with the hottest it gets to turbulate and wash them.
Iet them soak about 15-30 minutes.
I redo this hotttt step about 3-4x when I notice the water has cooled.
Then I blow out the coils and let them dry overnight.
I dry-burn them about once a week. (google dry + burn + Kanger for some youtube vids)
Some juices are extra gunky (usually darker ones) and I replace the coil at a half tank.
Some juices are extra clean and I can get 3 or more refills before I want a different flavor.
My coils last for months and I'm still using some 9 month old tanks. YMMV
