To maintain a Magic Bullet mixer, clean the unit frequently and order replacement parts as necessary. The Magic Bullet website contains a question and answer section for users looking to address specific maintenance issues.
Users must first determine if the Magic Bullet mixer is worth fixing or simply should be replaced. All Magic Bullet units come with a full one-year warranty. It is also important to clean the unit on a regular basis, as debris from frequent blending can build up throughout the interior. While hand cleaning with regular dish soap is possible, all Magic Bullet pieces are dishwasher safe as well, although cups should only be placed on the dishwasher's top shelf. The only item that should not be placed in the dishwasher is the power base.
When a Magic Bullet unit is damaged, a user should purchase replacement parts. Cross blades and new power bases can be purchased directly from the manufacturer. However, to be covered under the warranty, a user must provide proof of the original purchase.
Consumer Reports also contains maintenance tips for the Magic Bullet, as well as consumer feedback regarding the blender. Users report issues they have had with particular models and their experiences resolving these issues with the manufacturer.
