Whats the black deposit?

[Udai]

Been scratching my head.. but hoping someone has an answer..

All coils, however low the wattage is get burnt after a few days. Even if there was never a single burnt/dry hit, it will still gets burnt.. and there is a black deposit.. not just on the coil but also within the wick.

I know the cotton is the obvious answer, but even of the cotton isnt burnt while vaping it still has deposits on the coil.

I am guessing, its sugar/sweetness on e-juice, or flavoring deposits etc.. Does anyone know. has there been any studies. Did anyone just boil VG/PG in a pan and test if there are any deposits..

Its more than cotton. so what is it...

mostly burnt on carmelized juice.

Rule of thumb : the darker/sweeter your liquid, the faster it'll gunk up your coil. Caramelized sugars - hard to get rid of.

Pal of mine vapes menthol. His coils last for two, even three months. With stuff like vanilla or chocolate, they barely make it through the week.

Nothing hard about removing the deposit...... Remove the wick, if cotton/rayon, wash atty with soap/water or alcohol, pulse coil till crud burns off, rewick if removed. Don't need to remove silica, ceramic or stainless type wicks, they can be burned clean with the coil.

Lower watts = faster gunk
To high = burnt gunk

All coils Gunk. It is the Sugars/dyes and flavoring separating out and sticking on the coils.

Clean or Replace as necessary. All a Normal part of vaping.

The worst for me is ITC Nilla Gorilla. My coils are done for in 2-3 weeks.

All my ITC flavors would gunk my coils within days, if you are getting weeks.....wow.

That's the only one I'm having major issues with. The others are lasting 4-6 weeks.

I have to burn off my coils and change my cotton once a day with the juices I use. The taste is so delicious that it doesn't bother me at all. It's a part of the process.

My sweeter, more complex, dessert types gunk my coils up very fast.

BTW: It's the sugar getting caramelized (not burnt).

save that stuff and add more heat and millions of pounds of pressure and you end up with a diamond

i dry burn plus bathe my coils weekly. this gets rid of the gunk on my coils. I replace my cotton wicks at the same time.

there's this flavor called chai tea party from caterpillar ejuice.. it's probably the most delicious thing I've ever tasted. But it gunks up the coils within half a day! Solution: I got really good at extraction/dry burn/rewick procedure

Yeap this, if you have your watts too low it doesn't vape fast enough and thickens eventually caramelizing the sugars instead of evaporating.

It used to happen to me all the time when I broke my mod and only had a 15w mod as a backup...
