Hi All, I've been doing some digging into winterizing BHO, and I'm a bit concerned about the step where an open container of 190 proof Everclear is kept in the freezer while the waxes and lipids are being filtered. Isn't that step unsafe? I would be using my kitchen freezer which has a fan which I assume could spark the fumes. None of the written tutorials or youtube videos mention this as a precaution. Shouldn't I be concerned? My wife would have my balls if I blew up the fridge or worse.
