Okay so I just got 4 new attys in the mail and I blew the primer out of the 2 I bought brand new and blew out the ejuice that was left in the 2 I got from a fellow ECF member and went ahead and cleaned them w/ Vodka, after they dry do I need to put a couple drops of ejuice in them to keep the moist?? Or is it okay that they just stay completely dry.
