The Flip portable blender is very easy to clean. The cup and lid attachments are top-rack dishwasher-safe, but you can also wash by hand by adding a drop of soap to the cup, filling with water, and blending for one blending cycle. To clean the Motor Base, simply wipe it down gently with a damp cloth, and be careful around the sharp blade. NEVER submerge the Motor Base in water or run it through the dishwasher.
