Liquid darkening in genny?

[Nanooks]

I found this out by accident, ever since I started to actually use my fill screw not only did my gennies become completely pocket friendly but my juices seldom get darker any more. The caramelizing of the liquid will happen but when you vape with the fill screw in some how it doesn't get back into the tank. For me it has made a dramatic difference.

I have not tried capping the Phil hole cause it works well for me without, it seems like you would get more backwash as the air only has one way to come into the tank.

Well you have to actually try it and see if it works for you. I forgot to mention that my wick diameter is always less than the wick hole's diameter....so I don't choke the wick. Ever since I plug my fill hole I can carry my Gennies everywhere with me and not worry about leaking....and I always lay the device on its side. The added benefit is my juices don't get darker.

H2O - the universal solvent. A couple of guys have mentioned this and they're spot on. Flush and dry burn the water out. The next tank will stay pure much longer. I say this from excellent results today. It's like steam cleaning your wick. I'll be doing this after every couple of tanks from now on.

It's the juice...not the wicks. Oxidized or unoxidized wick it does not matter. the above post about not everything being vaporized is whats going on. It actually shows which juice vedors really put in the time testing juices. Some just fill a carto and faste but dont give it the long tank test and see how long it goes. Its just the nature of vaping. some juice darkens when it heats up and runs back dow the tank. I know with lime flavors even in a carto tank i can see it darken and clog faster.

That is probably because there is slight vacuum created by putting that screw back in causing a little pressure on the darkened liquid trying to make its way back down the wick.

I have found that if this darkening of the liquid bothers you, then just stick to the carto tanks and throw them away every two weeks.because of the extra filtering between the coil and your tank of liquid it wont discolor as quickly if at all.

So what's the consensus? e-liquid is the definitive factor?

Any wicking material gets a buildup of carmelized/carbonized stuff that doesn't atomize. Run a couple mls of juice through any wick and toss it into a couple mls of fresh juice and you'll see the same thing. We just notice it more in a genny because you can see it and your wick is in constant contact with a tank of juice.

Some guys over on reddit believe the color change is due to the fact that youre not vaping the "coloring" in some juices. IIRC from the one or two threads there, they said when burning tobacco or other herbs and you blow the smoke onto a piece of paper towel, you can see the soot and tar. When vaping and blown through a paper towel, there are no signs of color, with heavily colored liquids like pluid and some red juices. So, when you vape, you're vaping VG, PG, & flavorings whilst keeping the color in the wick which turns dark and seeps back down.

I am in no way saying that is the correct reason, that's just what I have read.
