I'm just here for the answer. Yesterday I cleaned some up by crushing it and washing it in 100% acetone in my Buchner funnel then I boiled some distilled water and pipettes it in until everything just dissolved. Then I nuked some acetone to get it hot and added it dropwise to the mixture which was sitting in the pan I boiled the water in (double boiler style) until it turned cloudy. Then I added a few more drops of water until it clarified. Then I put the lid on the jar and wrapped it with a towel to cool.vafter a couple hours it went in the fridge. Before bed I put it in the freezer. This morning it was a frozen slurry that wasn't really separable so I heated it up and evaporated all of the liquid. Let it solidify and scraped it out of the jar onto some foil and put it under a lightbulb. What I have now is amorphous crystalline nodules, but it did lose 23% of it's weight and tastes way better and gets you high more easily.
Summary; the acetone rinse was reasonably effective and the recrystallization was useless
