I just received my first E2 Ceramics and want to do this by the numbers. Is there any special prepping necessary such as cleaning or inherent fluids that need to cleaned/cooked off. They are Royal Smokers 808's from Clouds of Vapor. I'm planning on using them with regular 808 batteries plus an adapter to fit my Hello 16 batts, mostly in the 3.7 volt range. Most of my juice is BWB. Does running a plain unflavored juice with like 70/30 pg/vg at about 24ml have any benefit? TIA. . .
