Both brands offer dishwasher-safe jars and blades for their blenders, but some models also have self-cleaning features that make cleaning easier. For example, the Hamilton Beach Professional Quiet Shield Blender has a clean program that runs a cycle of water and soap through the blender. In contrast, the Oster Versa has a pre-programmed soup setting that heats the jar and loosens any residue. You may use warm water and a small amount of dish soap for manual blender cleaning.
