I just evaped a 1/4 gallon of 153 proof diesel last night from my trimmer clean-out. 2x pyrex dishes, fan on high speed and 10 hrs later all evaped. I then heat my oven to 170*, turn it off, place evaped dishes inside for about 30 mins (the oven temps drop significantly when turned off). this help dry up any remaining milky water from the dishes. scrape the next day. always super nice amber color in the bottom of my dishes. I make all my edibles from this stuff.
