I doubt if I will be investing in more nic anytime soon. Any cash I have to spend on this will be making my favorites of those tiny bottles into larger versions.
I have just been running them through a couple warm cycles in the ultrasonic cleaner. I do have a slow cooker what kind of time do people use for that?
I usually do tobaccos for four hours, a hour or two for anything else, then at least 24 hours before any serious judgment. Some tobaccos will continue to develop/change, usually for the better, for weeks to come. I use the low setting and keep the lid cracked about half an inch, this keeps the water temp ~150.
