Black residue in a Cisco 306

[sjoat]

Anyone know why this weird black juice came out of my 306 when I blew it out?

I've always used 510s, just tried this for the first time a few days ago and really enjoying it. All I did before first use was prime it like usual with my juice (which is clear!). I have been alternating between three juices but they're all clear so I doubt the black stuff is from the juice. Maybe, don't know.

Sounds like burnt juice to me, get some high proof alcohol (cheap stuff) and soak it in it over night, blow it out, dry burn and you have nice clean atty

Yep, sounds like burnt juice.

On a 306 especially, if you let the atty get to dry you'll burn it.
I have similar issues w/ 510's if I don't keep the atty wet.
Cleaning it could get all the black out.
Do you get a burnt taste? Usually when it gets like that (at least for me) there is no getting that taste out and I toss the atty. YMMV
