To clean the jar, Ninja recommends that you either hand wash it or use the ‘CLEAN’ function. It’s important not to submerge the jar in water or put it in the dishwasher, as it can damage the heating element. The ‘CLEAN’ function is a six-minute cycle that uses the heating element to warm up the water, and quick pulses to dislodge debris.
Cleaning the blender of smoothie debris is relatively easy, as you only need to run a ‘CLEAN’ cycle, rinse the jar to remove any remaining debris, and wipe down the rim since it was sealed. Cleaning the jar of almond butter by hand is near impossible, as there’s a lot of almond butter that gets stuck under the blades. The ‘CLEAN’ cycle does a good job of cleaning most of it, but you might need to use the provided cleaning brush to dislodge any almond butter stuck at the bottom of the jar.
The lid, the center cap, and the tamper are all dishwasher-safe.
