A good option is to rosin your traditional hashes ... gives a good return and gives you some more options.
Hey
@herbivore21 is there any way to clean up my traditional hash rosin? Its super nice and tasty and coming out clean (using 25 micrin metal screens for pressing) but leaves a lot of residue would be nice to clean up even more ... would it be worth winterizing or something? (Didnt really wanna use iso with non solvent extraction)
Oh damn just saw this now! Sorry man for some reason I never noticed the notification.
I do not recommend using solvents to clean up hash rosin. You would be much better off just using ethanol to wash the hash in the first place rather than rosining it and then winterize.
Also iso is nearly useless for winterizing. Frozen washes with iso are still helpful of course, but in terms of causing the wax/lipid fraction to solidify, only ethanol and methanol get it done reliably - and the latter shouldn't be used unless in a closed loop system where you're lab testing for solvent residue.
Short of finding finer screens (I don't know of many options for this myself, but I'm sure it is out there), you might need to change to another extraction technique to get something that leaves less residue. Does the oil taste bad at all or is it just the residue that bothers you? As a regular full melt dabber, I have come to prefer that level of residue (which qtips off the nail so much more easily than a rosin stain after dabbing that) personally and know that the best tasting concentrates actually leave more residue than the average stuff in most cases.
Some pics of the material might help give an idea of what you have?
