Oh, okay. I was taking the top wick out just because a guy in a YouTube video did that. He also cleaned up the black stain on that wick with a small blow torch-like lighter. (I didn't do that part.) "Organic" cotton? Would the cotton in a medicine bottle be organic? I don't think I could build a "neat" wick out of that stuff, though. I'll just leave the old one in, but then it will be hard to see if the coil is glowing.
Edit: I pain-stakingly put all the pieces back in, both times. Seemed to work better the first time I did it, than the second.
