how do i clean my magic bullet blender cups when stuff is really stuck on?

Diagnosis

Stubborn residue stuck to your Magic Bullet cup is common, often caused by blending thick, starchy, or protein-rich ingredients (like nut butter, oatmeal, or raw egg) which can dry and adhere to the plastic. Standard rinsing isn't enough to break this bond.

How to Fix It

First, always unplug the power base. For the most effective cleaning:

1. Fill the dirty cup about 2/3 full with warm (not hot) water and a few drops of dish soap.
2. Screw on the cross blade assembly securely. Place the cup onto the power base.
3. Press down and pulse or blend for 20-30 seconds. The vortex created will force soapy water into every crevice of the blade, loosening grime.
4. Remove the cup, unscrew the blade, and discard the soapy water. Use a soft bottle brush or sponge to lightly scrub the interior and the blade base, paying special attention under the rubber gasket seal.
5. Rinse all parts thoroughly and air-dry.

If That Didn't Work

For extreme cases, create a deeper cleaning solution. Try one of these in the cup (without blending):

• A paste of baking soda and water left to sit for 15 minutes.
• A 50/50 mix of white vinegar and warm water, left to soak for 30 minutes to dissolve mineral and protein deposits.

Heads Up

Never use boiling water, as it can warp the plastic cups. Do not submerge the blade assembly's metal drive socket in water for prolonged periods, and never clean the blades in a dishwasher, as this can cause rust and dull the edges. Always ensure the cup and blade are completely dry before reassembling for storage.
