Query: Unsatisfactory

The electric pot is not easy to clean as the lid does not come off therefore there is only a small opening to reach in to dry out this pot after use.Because of the above condition we have a mold mildew that we are unable to stop from returning. After I scour the area in the bottom of the pot and have gotten rid of all residue after the 2nd or 3rd heat cycle the mold is back.
