E-Juice Discoloration

[Bizchum]

Even after thoroughly cleaning the tank the e-juice still changes its color. Is the residue that causes the discoloration of the juice carcinogenic?

No, what usually happens is the cooked juice in the wick gets pushed into the tank from a change in pressure and darkens the liquid in the tank. Don't worry about it. If it begins to change the flavor of your juice, then it's time for a rewick. This used to happen all the time with my Kayfun LPV2.

Looks like you need a coil change, if what you're talking about is you putting the juice in the tank and while vaping it gets darker.

I had a nautilus mini and after about 2 weeks on the same coil my yellow liquids would become a light brown throughout the day. It also effected the flavor.

I had some COPYRIGHTDMCA cereal in mine and it started tasting funny. My buddy said it tasted like coffee after he tried it for a bit

heat caramelizes the sugars in the juice. Not an issue unless it tastes bad or gets too thick to vape properly.

It is usually not discoloration, but more coloration, Ive had clear juices turn brown while vaping. Its the heat. Its also why your coils turn black. Gunk. Be happy, its a lot less gunk than would go in your lungs had you been smoking the carcinogen sticks.

Things that make juice go dark, Heat, air, light. You eliminate exposure to those your juice will never change color.

The bigger the tank - the more this can happen. That is one of the reasons I am more particular to smaller tanks - I would rather refill more often - I can taste the difference once it starts to darken and with large tanks that can even happen with a new coil if it takes a while to vape through the whole tank and how much heat you are exposing it to.
