Matters needing attention in using ceramic rice cookers:
Don't use detergent to clean, because detergent will penetrate into the cracks in ceramic pot. If it is not cleaned, the detergent left in the gap will enter the food the next time it is used. Therefore, it is best to wipe it with starch and then rinse it with water.
Because ceramics are breathable materials, do not wrap them in plastic after washing the pot, but wrap them in paper and put them in a place with moderate temperature and ventilation.
