First of all just like to say I've been using e cigs for about a month now and absolutely love them. Since the first day using them I have quit analogs completely. I have read a ton I love this forum, so much information. My head might explode. Anyway just a couple of questions. I only have used the joye 510 and tried the ptb mod. I am not too crazy about it, so today I picked up the marineland blue foam size U. I have read on other posts that I should clean it with mild hand soap. Can anyone recommend a mild hand soap and how I should clean it. Also I picked up a multimeter and my atty is reading 2.6 which I am assuming is ok. How do I test the battery.I think thats it for now but im sure I'll have more questions as I go along. Your help is much appreciated.
