I just had a bottle of VG go bad on me. I was hoping someone would respond to my thread on the subject, but no joy yet. The liquid was fine when I tested it last week, but when I put it in my new 401 attys, I thought the attys had been dipped in poison. Bad chemical taste, and the vapor was more like smoke from a plastic fire than the nice
vape I got from the same bottle a week ago. I smelled the bottle of liquid, and there was the smell to go with the taste. Cleaning the attys with water took the bad smell away. Still don't know what went wrong. Too bad, I can't tolerate PG and I love the taste of VG liquids.
I wonder if similar things have kept others from enjoying VG.
