When it comes to cleaning immersion blenders, rinse the blending shaft as soon as you’re done. Although many immersion blender shafts are dishwasher safe, such as our winners, it’s still helpful to rinse them as soon as you’re finished blending. Otherwise, food can dry and harden on the blades and become a pain to clean even in the dishwasher. My favorite cleaning tip is to blend some hot and soapy water with your immersion blender. The blending action helps all the soap circulate and gets everything really clean. Just don’t get the handle wet. It houses the motor, so you should always keep it dry. Any water can damage it and could cause electrical injury. If it needs to be cleaned, all you have to do is wipe it down with a damp cloth.
