When washing with isopropyl alcohol or ethanol do a quick was with dried and frozen material and keep the bottle of the alcohol in the freezer too. Put your sugar trim, larf, popcorn, whatever youre working with, in a jar and in the freezer overnight. Keep 2 or 3 empty jars in the freezer and put double coffe filter in them. Unbleached preferably. Pour your ice cold alcohol into the ice cold jar, close the jar and shake it like fuck for about minutes then pour it all in the filter equipped jars and leave it all in the freeze to strain as it's gonna take for a while. You can do a second and a third wash if you like but the return will be insignificant and dirty.
You could also make some canna butter for the simplicity of it.
