If you're really picky like me, you'll actually rinse them out with hot water and let them dry before you use them.
That's the way i use new atty's too. I just cant have the vapor of the factory juice in my mouth. It's not that it has a very bad odor or what, it's mostly tasteless for me. I just dont like it without any taste.
Dont forget to put two or three drips of juice in the atty after it's dry and then put on the depot. Wait another minute letting the juice flow in the fibres.
