Cleaning the Breville Boss To Go is quite easy as its jars and blade assembly are dishwasher-safe if you put them on the top rack. If you want to handwash it, you can use warm water with soap, but if you want to use its blending mechanism to wash the interior of the jar, the manufacturer recommends using cool water due to pressurization. Almond butter is a bit harder to clean, as you need to let the leftovers soak for a few minutes.
