Hey folks, got a newbie question.. I know that people urge others to use only distilled water when diluting eliquid. But when t comes to cleaning, people tend to use tap water. 1-Should I use distilled water for cleaning as well? I mean sometimes the cartridges still hold couple of drops from the tap. Would it be dangerous to smoke it? 2- Should I clean the atomizers and cartridges out of the box or are they safe to use? Thanks in advance!
