This uses the blender itself to do the scrubbing - quicker than a deep clean, and good for regular upkeep between deeper cleans.

1. Add a small dab or two of dish soap into the soiled cup.
2. Fill the cup about a third of the way with water.
3. Attach the blade, making sure it's screwed on securely. Handle it carefully - it's sharp.
4. Place the cup onto the power base and blend for 20-30 seconds. Never blend hot liquids or foods using this method.
5. Rinse the soapy water thoroughly from the cup and blade, then towel dry or place the parts on a drying rack.

If caked-on residue remains after this, see How do I deep clean my NutriBullet cup and blade? for a longer soak-based method instead.
