ok bros its pretty easy..... make your butter as usual....then get a glass cup or a glass jar put the cannabutter in it.
Get a small pot of water and heat it on the stove...place your glass container of cannbutter in the hot water and let it melt about 1/2 way...
remove the glass from the water continue to stir the butter until its melted..... now add hot water to your glass of cannbutter and mix the 2
together......set in the fridge and let solidify and seperate.
This process is called a liquid-liquid extraction, and takes advantage of the different solubilities of polar (salts) vs nonpolar (hydrocarbons) compounds in polar (water) vs nonpolar (oil) solvents
Repeat the melting and water adding cleaning process until the water is clear(about 5 times). I use a pulp strain to pour the water through to catch any cannnbutter that falls out
Use a knife and make a hole in the middle of the cannabutter in the glass to drain out the water from under the butter.
This is 2 sticks of butter...... I always do 2 sticks of butter (1/2 pound)....most recipes call for 1./2 pound or a cup
......................................this is after one cleaning, butters cold......................................this is after 3 cleanings, butters warm.......big difference
