No tools are needed to clean Ninja blenders. The Mega Kitchen System, the Professional blender, the Nutri Ninja and the Ultimate blender all require the same cleaning methods. The motor base is wiped clean with a damp cloth, and the pitchers, lids, blades and attachments are dishwasher-safe.
While the pitcher is cleaned on the bottom rack of the dishwasher, the smaller pieces are placed on the top rack. Another way to clean a Ninja blender is to fill it three-quarters full with warm water, add a small amount of dish washing liquid, put on the lid and hit PULSE several times. After the blender is clean, all components are rinsed under running water. The blender should not be stored until the pieces have dried thoroughly.
