One of the most challenging part of using your Vita-Mix is how to get everything out of that deep container - especially with nut butters.
This is the best I've come up with: try ...
Plan to make a green smoothie after making your nut butter. Once you've made your delicious raw nut butter and scraped out what you can from the depths of the Vita-Mix container, don't wash it! Instead, make a green smoothie in there. That way you are sure to use the that bit of nut butter at the bottom that you can't reach.
At the very least put some water or nut milk in there and make a delicious drink.
