I have started learning to at least clean my coils and dry burn them. I have been using white cotton yarn to put in a new flavor wick. But is seems like no matter what I do none of my flavors taste right. At least not to me. My wife has been using the coils I clean and put flavor wicks and she seems fine with it. It seems like a chemical taste to me or something. Is it just me or am I doing something wrong?
