I do the vodka soak all the time and I have a few tips.
1st - there is always (I have heard) the possibility that you could destroy the atty. Make sure you have a spare atty before you try this. Also honestly, it will take your atty out of commission for a few days. (dry time)
I have done the vodka soak alot and never killed an atty. I think some people THINK they killed their atty but they really didnt, they arent patient enough.
2nd - Soak it in a non flavored vodka. I use Smirnoff.
Soak it for 3 hours tops. Soak it in a cup, swirl it around in the cup. Blow
thru it, both ways, swirl again, etc. Rinse with water.
Stand it on end, let it dry for a few hours, flip it to the other end, let it dry more.
Forget about it till the next day (this is why you need a spare atty).
The next day, do some dry burns, and try some drags (a usb pass
thru is best to save ur battery). If you dont feel heat, set it on end again. Wait another day. These things really take time to dry.
On the next day, you should get heat, and even see the atty glow, but you wont get any vapor if you put a cart in. This means the wick is still wet. Give it some good dry burns, and drags, and set it on end again for another day.
By the third day, burn, drag, burn, drag, until you can put a cart on and get a hit. It takes some time. If you dont after 10 mins or so, set it on end again for another day.
By the fourth day you WILL get a drag. Again, dry burn, drag, (the drags are to get airflow past things to let the heat dry the wick), burn drag.
Periodically put a cart on and try to get a hit.
I have had this process go 2 days, and as much as 4.
I know this sounds like a pain, but if it saves you an atty, its worth it, especially since they may be in high demand and low supply someday.
Hope this helps.
