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.
