2. Remove The Blender Jug

The blender jug must be put away most importantly. Separate the base of the blender from the top glass or plastic pitcher by taking it apart.

When you’re done sharpening the blades, you can choose to wash the plastic container if you want to combine a smoothie.

Once the sharpening is complete, you can clean it again. Don’t forget to clean the remainder of the blender while you’re doing this.

A brush, cloth, or gentle dishwashing will work.

3. Remove Blade Assembly from Blender

4. Wash The Blade

Now is the time to give your blades another rinse in the warm, soapy water. You may successfully remove any food particles or hardened food bits from the blade with a brush.

Remember that even a dull blade will still cut you if you hold it incorrectly. This kind of accident is best avoided.

Another thing is that rubber gloves should always be worn whenever handling the blades directly. Your skin is at least somewhat protected by it.

Make sure to carefully clean the blades, and keep an eye out for any traces of food. Take them out using a scouring pad.

Metal pieces can be easily removed using a sponge.

Before sharpening the blade of a Ninja blender, it is essential to wipe off any residue or debris from the blade assembly. Use a clean cloth or paper towel to carefully wipe the blades, ensuring all food particles and buildup are removed.
