Kashering an Electric or Gas Regular Oven

To kasher an oven that is not self-cleaning, you must:
  • Remove any deposits on the walls, racks, and window.
    Note If there are stains or deposits, you must clean them off or burn them off. If the stains or deposits do not come off after two cycles of using strong oven cleaner such as Easy Off, the oven is considered sufficiently clean.
  • Turn the oven on to its maximum temperature for 40 minutes.
    Note Self-cleaning ovens attain a higher maximum temperature than do non-self-cleaning ovens.
