black stuff in protank

[errolng]

had a funny taste suddenly while vaping.
when i looked into the central tube, i could see that there was some black stuff stuck to the side.
tried scraping it off with a needle but nothing comes off and it is really hard.
put it into boiling water as well but it doesn't help.

any ideas?

 

[errolng]

ok. after like the 3rd soak i managed to dig it out.
no idea what it is though.
its actually light brown and looks a little like wood chips.

that's probably gunk from the ejuice, try to dry burn it and blow the gunk away, it works faster and should save u sometime. after u dryburn u can proceed and wash the coil or just add more juice and vape!

 

[errolng]

wasn't on the coil.
was in the center tube which goes through the whole tank

just happened to my other protank.
could it been something burning and rising up the tube?
doesn't have a burning taste, just a very weird one.
only vaping between 7.5-8w though.

how long after washing and changing new coil this black stuff arises?

 

[errolng]

not sure exactly but i think i cleaned and dried for about 2-3 days before being used.
i get the weird taste after roughly 1ml of vaping?
not 100% sure though.

U soak in water too long. Rust starts to appear. Either that or u did not dap it dry after soaking. Air+water = rust on metal.

 

[errolng]

definitely not rust as it only appeared after i vaped on it after a while.
not sure if its bad juice combo with the protank some how.
will try again later or tomorrow with the same juice and a different one and see if it happens again.
