The removable grinding bucket is dishwasher-safe. However, you don't really need to clean it at all! If the bucket is not jammed with processed food waste, you can simply continue to add food waste to the bucket and cycle as usual. Any residue stuck to the bucket is almost always a cosmetic issue, and caused by the oil/grease or moisture content of the unit cycle. For an all-natural clean, try cycling citrus peels by themselves! This will also help to eliminate any trapped odors in the unit's ventilation system.
If dried food waste is stuck to the bucket, soak in warm soapy water to remove.
CAUTION: Do not reach your hand into the FoodCycler® Eco 5TM bucket, as the blades are extremely sharp.
