juices getting darker in the tank

[bkkdaytrader]

I usually keep adding the same juice to the same tank till I decide to change the juice-then I will clean before changing.

Now I notice juices getting darker as the refills progress--is this the sign of dirty coil? or??

Coil plus sunlight can darken juice.

Also - it may be the sweeteners in the flavor cooking a bit.

It definitely can be an indication of a coil beginning to "gunk up", if the color change is drastic it's a dirty wick/coil.

thanks everyone--well my juices are sweet--but also maybe after 4-5 tanks its time for a coil cleaning

Best to Vape dry and clean every few tanks or every tank if really dark e-liquid is used. A quick rinse/Dry and dry burn of the coil and you can get 10-30 tank fills before needing a new coil.(design dependent)
Dark e-liquid is Caramelizing e-liquid from heat. It is also thicker. Topping just keeps escalating the effect. Coil if being hammered by thickened Flavor/sweetener laden e-liquid and building gunk up even faster.

My Kayfun Lite Plus is on the same Coil and Cotton wick as installed over a Month ago. Using a lighter color(almost clear) E-liquid ant still Vaping Excellent. Tank gets filled 4-5 times a week. 4.5Ml

I had a certain juice that would do this no matter what. I even tried it with a fresh new coil in my 30s and it would still get dark. I think it's somewhat normal with certain juices. That's the general consensus anyways.

The amount of heat, and air that e liquid is exposed to will cause the liquid to darken .. I find that my e liquid gets darker, faster when I use lower ohm builds, but all e liquid will change color. Sweeter, carmelish e liquids tend to get the darkest.
