....3- put atty and rubbing alochol in cup -stir and shake for 5 mins...
I wouldn't want to take any chance of inhaling the Isopropanol (or worse) base or any of the additives. Even if you're a non-drinker, Vodka is easy and cheap enough to obtain in small bottles. I'm pretty new to vaping but I've used this alone to successfully renew a few attys as well as cart filler.
