Hey guy's Been vaping 70vg/30pg but anything over 30pg I get to coughing and sore irritated throat so I got me some 100%vg also but my flavors are PG based so it not quite 100%vg but damn close. I notice when I vape high VG it wreaks havoc on my Dual Claptons. They get burnt looking like and a little gummy and I was coughing up a storm when that happenes. My question is can I clean those coils off and continue to use them or do I just need to replace them? I know it's not the cotton cause I just changed it yesterday. I got me some 28 gauge wire on the way but won't receive it till Friday so I've been vaping off factory EC's till I get the new wire. The Dual Claptons I am referring to are the ones that came with the Lemo3 tank. What can I clean them with. I don't have a wire brush on hand. Is there a solution I can use or is the wire pretty much spent ? Being retired I vape all friggin day and most of the night.
