quickest and safest way to clean that i have found, is one i stumbled upon by accident. i had a stuffed battery on my 901 - somehow a drunk chick pulled the bottom of the battery off while attached to the atty- the threaded bit with wires haning off was still attached. So next week at work for a bit of fun i screwed it onto a nearly stuffed atty, put a few drops of
juice on it, and put it on a 6v torch batt for a few seconds. man, the vape off that was awesome!! But, i noticed afterwards that the atty was good again- im still using it 2 weeks later. so now, as a weekly ritual, i have a few puffs on the 6v at the start of the week, through all the attys i have on rotation(6), and they vape up good. even attys that seem like they've 'lost it' come back after a good few puffs. no soaking, no draining, nothing. just a good blast every week. havent bought attys since my first shipment, and i still have 3 unused ones in the box( i started with 10), ive only managed to kill one atty in 3 months, and that was from dropping it i think
