Rice cooker inner lid and steam vent: clean food residue after each use
Residue on the inner lid and steam vent may cause odors or affect steam release. For removable parts, follow the rice cooker's own manual, wash gently and dry before reassembly.
Zojirushi's maintenance guidance advises removing washable inner lids after use, clearing rice and starch, and drying parts before replacement. Not every cooker has the same gasket and steam-vent mechanism; never force a part apart.
