Hi guys so thanks for all the tips on how to clean coils. Last night cleaned my demon killers framed clapton that I have had installed on Friday they were brand new. Cleaned them last night as you can see below and see second pic below. So cleaned coils Sunday evening today after vaping maybe 21 ml of juice they are black as black can be. This can't be normal! What gives? I see people saying their coils last them a month ? Help I vape currently on loaded doughnuts and marshmallow man!
