Sanitizing Flooded Refrigerators and Freezers

If water has seeped into refrigerator or freezer, sanitize it before using it again. If insulation is wet, the appliance will probably have to be discarded eventually, since it may run continuously, frost up on the outside, or develop bad odors. Before cleaning and sanitizing refrigerator or freezer, be sure motor and freezing unit are in safe working order.

1. Dispose of any spoiled or questionable food.

2. Remove shelves, crispers and ice trays. Wash them thoroughly with hot water and detergent.

3. Rinse with a disinfectant solution (1 teaspoon chlorine bleach for each gallon of water).

4. Wash the interior of the refrigerator, including the door and gasket, with hot water and baking soda.

5. Rinse with disinfectant solution.

6. Leave the door open for about 15 minutes to allow free air circulation.

7. If odor remains, place several pieces of activated charcoal in an open metal container, or use a commercial refrigerator deodorizer.

8. Wash the outside of the refrigerator with a mild detergent and hot water. If stains are difficult to remove, or soil particles remain, use a mild abrasive cleanser. Be careful not to damage the finish.
