I've been vaping on my quad coil for 3 days or so. Probably 5 tankfuls at most. Mostly between 90-100 watts, never going over 110. I disassembled the tank today to do some routine cleaning and noticed that the cotton in the coil is black. I'm using 90vg cereal killa. Was surprised to see the cotton so dark after just a few days and operating it way under it's max specs. Coil still tastes fine, i'm just a little hesitant to keep using it after seeing the condition of the cotton. Anyone else look at their coils? Thoughts?
Mine was pretty black after 2-3 weeks. Rinsed it out with vodka, then hot water. Seemed to do the trick...vaping on it now.
