Hand Blender How Do I Clean My Hand Blender With Out Blowing Myself Up?

How do I clean my hand blender with out blowing myself up? - hand blender

I use a hand blender for food for my baby of 6 months puree, but in reality, the struggle for cleaning after each use. My husband proposed to her head in the water and turn it on, not sure if you kill me, or want to be useful! I have tried to use a brush to wash the leaves, but only on the street. How can I clean?
