How to Deal with Refrigerator Odor After a Power Outage

Refrigerator

A lingering smell in your refrigerator after a power outage is not only unpleasant—it can also be tough to eliminate. Whether the smell is caused by spoiled food, trapped moisture, or overlooked spills, the key to a fresh-smelling fridge is a thorough clean and a few preventative habits. Here’s how to get rid of refrigerator odor after power outages, or even when there hasn’t been one.

What Causes Refrigerator Odor After a Power Outage (and Even When the Power Stays On)

A refrigerator odor after a power outage is a common issue. When the fridge loses power, it stops circulating cold air. As the internal temperature rises, perishable food can spoil quickly, creating ideal conditions for bacterial growth and unpleasant smells. Even after power is restored, those odors can stick around.

But a bad smell in your refrigerator isn’t always tied to an outage. Even when the appliance is running properly, odors can develop from everyday use. Common causes of refrigerator odor include:

Forgotten or expired food
Spills that weren’t fully cleaned
Moisture buildup or mildew
Open containers with strong aromas

These issues can build up over time and may be intensified after a power outage—but they can also occur anytime regular cleaning and food rotation are neglected.

What You’ll Need to Remove Odors

To eliminate refrigerator odor after a power outage or anytime there are odors, gather the following supplies:

Baking soda or white vinegar
Warm water
Dish soap
Sponge or microfiber cloth

These simple ingredients are often all you need to clean and deodorize your fridge safely.

Step-by-Step: How to Get Rid of Refrigerator Odor After a Power Outage

Step 1: Empty the Refrigerator
Start by removing all contents from the fridge and freezer. Dispose of anything that looks spoiled, smells off, or has been stored without power for more than a few hours.

Step 2: Clean Every Surface
Mix dish soap with warm water or use a vinegar-water solution. Wipe down all shelves, drawers, walls, and door seals with a sponge or cloth. Be sure to reach corners and crevices where food residue or moisture may be hiding.

Step 3: Deodorize Naturally
Place an open box of baking soda or a small bowl of vinegar in the fridge. These natural deodorizers help absorb lingering smells over time.

Step 4: Air It Out (Optional)
If the smell persists, unplug the refrigerator and leave the doors open for a few hours to ventilate. This step can be especially helpful after a prolonged power outage.

What to Do for Strong or Lingering Odors
If you’re dealing with a strong refrigerator odor after a power outage, you may need to go a step further.

Remove and wash shelves and bins in the sink with warm, soapy water.
Use a paste made from baking soda and water to scrub problem areas or stuck-on residue.

For extra odor-fighting power, place one of the following in the fridge for 24–48 hours:
