How do I clean a blender properly?

The fastest method: fill the blender halfway with warm water, add a drop of dish soap, and blend on high for 30 seconds. Rinse thoroughly. For deep cleaning, disassemble the blade assembly (if removable) and wash each part separately. Never submerge the motor base. Most blender pitchers and personal cups are top rack dishwasher safe, but hand washing extends their lifespan and clarity.
