Hey guys! First 420 mag post! Lol. Well, just coming on here for a little help. I recently bought some bho off of a friend of mine's "caregiver" and the thing was still full with butane. I decided to try and purge it more by letting it purge on a glass Pyrex dish using a torch. I got it down to a clear amber color, but it is still really harsh on the throat. Any suggestions on how to further on clean the product? Maybe winterize it with everclear?
