The no-cook aspect might get cancelled by the clean up. In my experience with protein shakes the shaker bottles (how I make protein shakes) cannot be rinsed completely clean and if left at room temp will get ripe, like spoiled milk. So a bottle brush, soap and possibly hot water will be needed for a proper, healthy cleanup. At least for me.
