Daily Cleaning Routine
A simple daily cleaning process keeps your Ninja BL770 fresh and ready to use. Here’s a 5-minute routine:
- Unplug the Unit: Safety first.
- Disassemble All Parts: Separate the pitcher, lid, blades, and cups.
- Rinse Immediately: Prevent food from drying onto surfaces.
- Use Warm, Soapy Water: Clean with a non-abrasive sponge.
- Air Dry: Set all pieces on a drying rack or towel.
If you’re short on time, the self-cleaning method (see below) is quick and effective.

Every week, or after heavy use, give your Ninja system a deeper clean:
Self-Cleaning Method
- Fill the pitcher halfway with warm water.
- Add 2–3 drops of dish soap.
- Pulse for 20–30 seconds.
- Rinse and dry thoroughly.
Manual Deep Clean
- Use a soft-bristle brush to reach under blades and seals.
- Inspect for trapped food under the lid gasket and around the base.
- Soak tough stains in baking soda and vinegar solution.
