Cotton Rocks !!!! I use it on my rebuildable Vision clearo's ( a.k.a. Stardust )
I got 2 iClear30's and 4 heads.... wicks are ok, but I have used it as is for a few days, washed it out and pulled the silca wicks out and used regular old everyday cotton balls they sell at wal-mart or your wife/girlfriend might have in their make-up case.
It boggels my mind all the crap people do to clean there stuff..vodka, ring cleaner things, alot of other way of the hill things. Just rinse and dry things off..anyway..pull wicks out but make sure the top coil is NOT touching the bottom coil, nor the sides....then pull some cotton off the cotton ball roll inbetween your fingers until long and thin then thread it into the bottom coil, pull through then a little fluff and cut to fit...repete along with the top one.
Once again double check that the coils are NOT touching each other nor sides. Screw back on the tank, fill and wait 5 mins or longer for cotton to soak up juice. At 3ml it will soak up to .5 ml or more...then enjoy it.
Also when there is no juice left in tube you still have along time with just the wet cotton from your juice to vape
