You can clean up any extract very well by boiling it first in 70/30 iso/water rubbing alcohol. This will cause any green chlorophyls to swell up along with the waxes which get denatured too by the alcohol. Iso and water form an azeotrope so the iso will not boil off completely at first but the mix will become a higher percentage of water as you boil it off. Extract will drop out of solution as the percentage of water increases and you will be left with an emulsion of water and compound. Putting the flask then into the freezer hardens up the extract enough that the water (likely chalk white with pinene) can be poured off easily.
Then put a few inches of either white or brown aluminum oxide, 220 grit abrasive grade on the top of the glass frit of a Büchner funnel. Wash the boiled extract through the alumina at room temperature or lower with 70/30 iso/water (rubbing alcohol) by pulling a vacuum. The denatured proteins and waxes along with the green chlorophyls have all been subject to hydrolysis during the boil. Pinene if present will turn the water chalk white. The swollen waxes and green gunk are stopped on top of the alumina column and will not pass. The cannabinoids and terps all pass easily with water white pinene laden water generally eluting first (I toss this).
After the boil the solution must be cooled to at least room temp for this to work right otherwise the solvent will pull the chlorophyls and waxes through the alumina if it is hot. This method is a complete clean up and you will see a thick gunk layer form on top of the alumina. You can skip the boil and just denature the waxes in the iso/water (or methanol) and it will still catch the waxes this way but not the chlorophyls - those must be subjected to hydrolysis first or they will pass the alumina. The iso allows the water to come into close contact with the extract which is not miscible in water alone. This is my SOP prior to further refinement.
note: I do not use ethanol in my lab, however since it too forms an azeotrope with water it should work in like fashion. Methanol works to denature and grab a LOT of waxes when passed through Alumina but it does not work well for the boil because it does not form an azeotrope with water and quickly boils off first. This prevents the extract and water from forming an intimate contact during the boil.
