Recently I've been reducing the amount of times I have to rebuild, and the amount of wire I use by just replacing the wick. I just remove the coil and take a torch to it to get the gunk off, and then put some new cotton in. Ive done this about three times already to one coil, and it tasted new every time. Is there a reason why people replace the coil every time? I understand the wire may get worn out over time, but it seems to last much longer than how long people usually use them. What I'm doing is saving me a lot of time by not having to rebuild as often, so I know there must be a good reason why other people don't reuse their coils.
