• Unplug the refrigerator and thoroughly wash the inside of the unit with a mixture of two tablespoons of baking soda dissolved in one quart of warm water. Wash the shelves, drawers, accessories and gaskets. Be sure to wash corners, crevices or grooves where odor-causing liquid may have settled. Dry thoroughly.
• Place activated charcoal or activated carbon in a shallow bowl and leave it in the refrigerator while it is running for several days. The charcoal or carbon is available where aquarium and/or plant and garden supplies are sold. It will become saturated but can be reactivated by heating in a 300 degree oven for one hour and then put back into the refrigerator. Try this for about 10 days.
• Place toothpaste (not the gel type) on small pieces of foil and set in several spots in the refrigerator.
• Lightly crumple sheets of newspaper and loosely pack a refrigerator shelf which has been emptied of food. Sprinkle the newspaper with water and close the door. Replace the newspaper every 1-2 days. In 5-6 days the odor should be gone.

If odor gets into the plastic lining or the insulation of the refrigerator, it can take a long time to dissipate.
