Where is this gunk coming from?

[graywoulf]

I just noticed that my clearomizers (eGo thread) are getting a buildup of black residue on the threads and I am trying to figure out where it is coming from. Is It from dried leaked juice or from the metal corroding?

Dirt from your hand mixed with juice mixed with saliva mixed with dust from the air and a little oxidation.

Poster before me is probably correct, but it might help if we had a picture.

it is very common with mixed metals, Isopropyl alcohol 91% is really good for cleaning it

It's the same process that occurs over time in flashlight battery cap threads. Dissimilar metals create some byproducts when electrical current flows through slightly resistive contacts. Some of it is carbon, like you see on relay contacts that arc when they make and break. The rest is metal dust from screwing and unscrewing the atomizer.

Very smart posters have answered your question. I am sure they all do it. Just clean 'em and vape 'em.

Yes, Isopropyl alcohol 91% is what I use. I go to a pharmacy and get the alcohol prep pads that are individually wrapped. I keep some in the car and in my travel kit.

Dust, dirt, juice, etc. is common.

Clean your threads on your atty and on the mod once a week with alcohol. Also the 510 pin on the battery. If this is an ego, also clean the contact pin on the charger.

Also, being as you're using an ego threaded clearo, that means your airflow is coming from your ego/510 thread ring. As the vapor is made, some flows back down to the threading ring and eventually condenses back to a liquid. Then the heat from firing the device evaporates some of it and you get juice sludge. Plus the di-electric corrosion mentioned above. Plus the whole dust/dirt/hand oil thing. Q tip and alcohol every time you take the clearomizer off. Clean the battery, too... especially prior to charging. The heat generated during charging can bake that sludge to a crust.

All right then. I guess that answers that. I will make the effort to clean everything as suggested. Thanks to all of you for the information and suggestions.

Yah and its creates quite a stir when peeps post pics of this horrible growth on their coils the same color as their copper center post. It happens with stainless steel too its just not as obvious.
