I'm just curious, because although I can get a coil to taste decent for a few tanks by swirling and making sure it's well wicked, I wonder if it's still better to clean them frequently? For example, the gunk that's on coils is got to be bad for you when it's vaped right? We've all seen the gunk smoke when we dry burn coils. The question is, do we breath that nasty smoke when we vape on a dirty coil as well? or does that nasty smoke only occurs during dry burns?
