The jug bottom contains the base that holds the blades to the jug.

The time has come for you to remove the blade.

The blades work with the rest of the device to create perfect smoothies, not by themselves. You want a clean blender with no harm done to any of its components. Wash away to encourage the soap water to loosen the seal sitting cozily between the jug and the blades. Quick Note: If your blender model allows for the blender jug and blade to remove as one, then fill your sink with warm soapy water and sink the container inside. Clean the rest of the device at this time too mild dishwasher and a brush or cloth will do. You can give it a second clean once the sharpening process is done. At this time, you can if you like choose to wash the plastic container in case you have plans to blend a smoothie immediately after blade sharpening. Separate it from the base, namely the big sitting portion ensconced in plastic and housing the motor.

The last thing you need is an electric shock for some reason that has nothing to do with you or the blender. To sharpen your Ninja’s blades and get it back up to its pureeing, chopping, dicing, and blending prowess, you will first need to unplug the Ninja.With the right tools and technique, you can do this at home. On such devices, the blender blades could do with a re-sharpening.Dull blades are never the case with new ninja benders, perhaps one that you have had and used for a few years.
