Does anyone really clean coils? Is it really necessary? If so, what's the best way of doing it? I've watched several YouTube videos on that, but I don't want to screw anything up and damage anything. I know that I ask a lot of questions, but I'm just trying to get as much info about vaping that I can without screwing things up. I have had so very much help on here with awesome advice! I welcome any and all info I can get. After all, there's only so much you can trust on YouTube.
