Hey everyone. In having an issue. It's new, and puzzling. I'm using evod tanks with rebuilt coils, organic cotton topped with 2 mm silica flavor wick on top. With a fresh built coil all is fine, however as soon as I clean my tank and refill it tastes awful. Burnt. To clean I rinse tank out with water, dry with a pipe cleaner. The atomizer it's self I wipe down with paper towel and the base too. I've noticed that the rubber grommet the firing pin fits into are getting charred where the coils is grounded, but I've seen this before and there's been no change in flavor. This is ruining my vaping experience, and I can't figure it out, any help is much appreciated !
