They don't like us to use links here, sorry, but I would order the 99% isopropyl alcohol online or go with the everclear. I have heard too many horror stories with using naphtha. Naphtha can be very dangerous and confusing in finding the safe to use naphtha. Either way, I keep hearing so many bad things about it, I would recommend staying away from it.

I have not tried 190 everclear myself, but my best guess is that it is just not as efficient. It can still produce premium oil though. I am pretty confident of that.

Maybe do your first batch with the 190 since you can conveniently get it. It would be good practice too. It should tide you over until you can order and receive the 99% isopropyl alcohol.

Good luck and God bless.
