A rice steamer must be allowed to cool before it's cleaned, and the interior pot's rim should be wiped before removal to keep particles from falling inside the cooker. The removable pot is then soaked in water and washed with soap, but the electronic base must stay dry.
The base and the lid come clean when wiped with a damp rag. Removing the steam vent and the evaporation chamber allows for a thorough rinsing of those pieces. Some models include parts that are dishwasher-safe, such as basket inserts and scoops.
Once all pieces are clean, they should be dried, and the steamer should be reassembled for the next use.
