Here is how to clean a blender in about 5 minutes: warm water, a few drops of dish soap and a quick blend. For cloudy buildup or stuck chia seeds, I use a baking soda paste or a vinegar soak that works on Vitamix, Ninja and NutriBullet.
Fill the blender halfway with warm water and add the dish soap.
Secure the lid and blend on high for 20 to 30 seconds.
Pour out the soapy water and rinse the blender well. If it still isn't clean, repeat using the baking soda and vinegar.
Notes
Timing Tip: Clean the blender right after using it, before anything dries on.
Stuck-On Spots: Mix the baking soda with a little water into a paste, spread it on and let it sit for 30 minutes. Scrub gently with a soft cloth and rinse well.
Cloudy Container: Soak it overnight in equal parts white vinegar and warm water, then rinse.
Motor Base: Never submerge the base; wipe it with a damp cloth instead.
