I hope he chimes in since the other answers from other places have only helped little.... I'm trying to finish post hast, but I don't want to fuck up. Everyone keeps telling me just evaporate which is what I don't want to do.... naphtha smells up the whole house and its just about winter here so open windows aren't as much of an option. It seems as though the spice would stay in the pot and I'd have clean naphtha in the receiving flask. I'm told I may end up with a bit of spice in my receiving flask(which is ok as it will be used for future pulls). I'm told my biggest risk is running the pot dry. I don't mind having to evaporate off a little naphtha, but liter(s) are getting time consuming, smelly, and annoying... How do you explain naphtha fumes....ummm... I was... uh, cleaning...yeah, thats it. I was just trying to remove this glue for the past three days..... If I get a vacuum there shouldn't be shit for smell until the still is opened. I'm figuring if the oder is a problem I can run tubing from the vacuum adapter and put it out my window. I'd only have to crack open the window then to get rid of all the smell.
