After Rewicking a Used Coil, I am Getting a Sour Taste??

[Penumbra]

Today (or more like last night) I decided to rewick a coil I had been using for a week.

Last week I coiled and wicked my Subtank Mini in a manner which yielded the best flavor I have ever experienced yet with vaping... my first RDA is on the mail to my house, so that will change things I am sure.

Anyway, I have been experiencing less flavor / wicking ability, so I figured I would rewick it.

I opened up deck, removed old wick, and proceeded to dry fire the coil just to clean it off a bit.

Once it stopped hissing and vaporizing leftover juice, just after it started to glow again, I noticed that as soon as I stopped firing, a little flame would appear, then die. So I continued doing 4 or 5 sec. pulses until little flames stopped popping up. I assumed that it was just small fibers of KGD left on the coil and in the vicinity of coil.

After that, I proceeded to re-wick, refill and then vape. Unfortunately, the flavor was kinda sour. I got ......, and thought maybe the coil was just too used, and I rebuilt and rewicked it this morning... all the same exact way as last week. But I still got this odd sour taste. Could it be that the flames of burning KGD threads (assuming that was what the flames were from) left some residue on the coil and was causing this?

Obviously, I should take the whole tank apart, completely clean it and rebuiild/rewick to see if it helps... but I'm taking a break cuz I have been building/wicking like non-stop all week; however, I still wanted to mention to ECF.

I searched "sour" and came up with 2 threads that reference a related issue but had no replies.

Maybe I'll be lucky and get replies..

The flames were probably e liquid. I've gotten a little one once or twice. I do rinse my coil and deck before and after the dry burn, and blot it dry each time.

Might be just needing more practice wicking. Don't get discouraged. It will be second nature soon.

ahh ok...

cool... thanks "neighbor"!

I have Dry Burned MANY coils in my Vaping Travels. Can't recall ever seeing Flames.

How does the Insulator look?

your getting (or I gave) the wrong impression.

Picture this. I have my iStick 50W in my hand, with the base of the Subtank Mini installed on it. On the "Sub's" base, is the rba-deck, w/ the cylinder/cap removed, thus exposing my coil. The coil has no wick in it.

@20 Watts, I pulse it a couple times, and it sizzles and vaporizes juice still left on and around coil. Then, after the sizzling and vapor dwindles, I start holding the fire button for longer... 1, 2, 3 and then 4 sec.

THe coil starts to glow now... but at some point, when I let go of the fire button, as soon as I let go, a tiny little flame pops-up right about where the post screws are... or maybe on the coil, but in the general "post" area.

Its a tiny flame that vanishes just as quickly as it pops up... so picture a glowing coil, and as soon as you let go, a flame pops up and vanishes in less than a second.

This is by no means a "deck fire".

All in all... if I thoroughly cleaned the coil and deck, and the juice is the same etc, then its got to be something with the wick right?.. whether its the material or something got on it somehow?

I wash my hands always before I even start taking things apart, and especially right before I do the actual wicking.

I wash mine, too, before wicking. Maybe there was some old burned ash left on your coils though. I wash first to get juice off everything. Then after dryburning because there's like ash left.

OK... I was Picturing more of a Deck Fire.

Maybe you had some e-Liquid Build up? Or Stands of Cotton? I dunno?

Sounds like Everything needs a Good Warm Water Rinse. And a New Coil never hurts.

 

[roxynoodle]

Yeah, tiny flames near the post screws are e liquid . I've had it once or twice when apparently I didn't rinse well.

A week is kind of a long time without rewicking, too. Coil could get pretty gunky, especially with certain juices.
