Juice turns dark.

[DanJiblets]

I only have this problem with one juice flavor. It has to be the juice. Same tank and setup as all my others. I have a fresh coil and tank, load it up, and in less than a day my coil is gunked up and turns my clear juice dark brown. Is this safe to vape? It's annoying having to finish it and rinse my coil. Usually I can just fill my tank/top it off without worrying about cleaning it all. Anyone else have this issue?

Yea, it usually happens with overly sweet or sticky juices and some tobacco flavors, they caramelize on the coil creating a brown crud, that in turn leeches back into the tank.

As long as its not ruining the flavor its pretty harmless

Cool good to know. It still tastes fine, just looks gross.

Yup like brown sludge, the cleoromizers are especially guilty of doing this

Using a subtank, lowest wattage possible. It's definitely the juice.

i have the same problems with certain juices in my subtank mini but mine turn orange/tan. nothing wrong with it, as long as its not black thin and flavorless

I've got some cherry cola that does that, the vendor even warns about it, apparently its stevia in there that does it according to the maker.

my darker sweeter flavors like cinnamon do that but after a long time of just sitting around. Nicotine on the other hand will turn yellow which could add to the effect
