Can find acetone in the paint supplies (will be with the other stripper and solvents). My assumption right now is either the acetone I got (jasco, all Lowe's carried) isn't pure acetone, the containers are too wide, I screwed something up, or... i screwed something up, lol. Gonna keep testing, i have about 1/4lb of both the waka and lawena left and won't be drinking it often (I have 2lbs of nambawan and 1/2lb of borogu i'm working through). In the acetone you can definitely see a difference in the kavas though, the lawena has a lot more of the tan powdery residue. The waka has quite a bit, then a lot of "stemmy" looking debris. The borogu looks like sand and has very little of the tan powdery residue. Not sure if you can take that as an indicator of quality or if it deals more with the grind.
