Ok, ended up deciding against the ISO/brine wash, I didn't even get much wax to precipitate in the iso, even in a dry-ice/iso bath.
I ended up using 151proof everclear, strongest available in mi.
I'm glad to report it works supremely well, 95% might evaporate slightly faster, but the lower proof worked very well.
A benefit of the lower proof(at least it seems a benefit) is that near the end of evaporation, you end up with more of the milky white water, which serves as a fairly good "water wash".
I pour out the white liquid as soon as its clear little to no alcohol remains, leaving a very clean shatter.
I'd like to try centrifugation in ethanol at low temps, but getting temperature down while simultaneously processing in a centrifuge posess a challenge.
Also, has anyone experimented with activated charcoal?
