Hi - At times the contents of the NutriBullet spill over. What's the best way to clean the interior where the cup gets inserted? Thanks.

Hi, make sure the unit is unplugged from the electricity anytime you clean it. You can use a damp cloth and even use a little bit of soap to clean in and around the base. For additional assistance with cleaning tips, you can contact our Customer Service area in the USA at 855 346-8874.
