Methanol extraction for precipitation of waxes works great with a little bit of water.
Methanol will push out fats and with addition to water, after the initial fat move will remove the rest of them fats.
I used warm extraction methanol , i use my delta cup bags to remove majority of fats, then filter using hot carbon scrub and then add water to anothet filter.
It doesnt take long, my keg takes me about 2 hours to do filter into a mild yellow/red crude oil that has very minimal amounts of fats and great color at end, i also take disty and do water wash with heptane then roto then dump into spd. Method really makes my product stand out.
Methanol is 2-1 and then i add about 1000 ml of water to my keg. I see fats precipitate.
