Removing Odors from Refrigerators and Freezers
Objectionable odors can develop in refrigerators and freezers. This happens when food is left too long or is improperly packaged, when the drain pan near the condenser at the base of the refrigerator needs cleaning, or when the refrigerator is turned off and the door is closed.

Check your refrigerator and freezer to determine
•	Warning lights show high temperatures or power
failure.
•	Temperature controls do not work.
These odors can be difficult to remove. Insulation absorbs some of the odor and sometimes makes removal impossible. Plastic-lined interiors absorb more odors than porcelain enamel on steel interiors.

To prevent odors from occurring:
1.	Clean the refrigerator weekly to reduce spoiled food odors.
2.	Wash the interior of the refrigerator using a solution of 2 tablespoons of baking soda per gallon of warm water.
3.	Defrost when frost is about 1/4 inch thick (manual defrost refrigerators).
4.	Keep an opened box of baking soda in the refrigerator to absorb odors. (Replace every six weeks to two months).

To remove odor, choose one of the following cleaning materials. Combining two of these may develop a toxic fume which could be fatal if inhaled.
•	Vinegar—1 cup per gallon of water
•	Household ammonia—1 cup per gallon of water
•	Chlorine bleach—1/2 cup per gallon of water
Wash the refrigerator with the solution. Rinse with clear water and dry.

A second method for removing odors is to use one of the following to absorb moisture that contains the odor:
• Activated charcoal
•	Silica gel
•	Kitty litter
•	Chloride of lime (slack lime)

These products may be available at pet shops, hobby shops, farm-supply stores, or hardware stores.

Follow these steps to remove odors:
1.	Disconnect the refrigerator.
2.	Clean the refrigerator using a solution of 2 tablespoons soda per gallon of warm water.
3.	Place charcoal, kitty litter, or silica gel on paper plates in the refrigerator.
4.	You will need heat and forced air circulation, such as that provided by a heater fan or hair dryer. Place the heater fan or hair dryer in the refrigerator.
5.	Leave the door open. Turn on the fan and heater.
6.	Be sure the refrigerator or freezer is disconnected when the fan and heater or hair dryer is in use.

If the odor still remains after you have tried one or more of these methods, write to the manufacturer. The address should be on the name plate of the appliance or in the instruction book. If neither can be located ask your local dealer or
