Moisture from food, spills, and areas around the seals can give rise to mold and bacteria. This produces smells in the refrigerator.

Spoiled food in the refrigerator also leads to a bad odor. It results when the food is not stored properly or the temperature is set incorrectly.

FAQs
Why does my refrigerator smell like gas?
There are multiple reasons your refrigerator smells like chemicals or gas, and one potential cause can be refrigerant leaks. Modern refrigerators use particular refrigerants such as R600a (isobutane), R134a, to keep the fridge cool. These are usually sealed to prevent gas leakage.
However, if you rupture the fridge wall during defrosting or an old copper line erodes, the gas escapes.
How to remove odors from fridge after a power outage?
A power outage stops cold air circulation, increasing the temperature in the refrigerator. Perishable food can go bad quickly, becoming the source of unpleasant odors. To remove odors once the power returns, clean the fridge thoroughly and disinfect it with 1 tablespoon of bleach in 1 liter of water. Then dry it completely.
It’s important to know the steps to follow during a power outage.
- Note the duration of the power outage. If it was less than 4 hours and the door was closed, most food will remain safe.
- Check the temperature of the refrigerator. If it is still below 4°C, the food is safe.
- Get rid of the food that has been at a temperature above 4°C for more than 2 hours.
- You can store non-perishable items such as condiments, pickles, and unopened drinks safely in the fridge.
How long does it take for fridge smell to go away?
While mild refrigerator odors take a few hours to go away, stubborn smells may take a few days or weeks. It may take several cleaning and deodorizing sessions before the fridge smells fully dissipate.
My fridge smells bad even after cleaning. Why?
If you are dealing with strong odors, they might take some time to go away. Additionally, your fridge probably smells bad even after cleaning because some smells absorb into the refrigerator’s insulation. This often leads to changing the appliance. Make sure to discard the older one safely.
Clogged evaporation coils can also be the culprit for stubborn odors inside your refrigerator. These are located at the back of the fridge and provide cold air to its compartments.
How does baking soda remove fridge odors?
Smells in the refrigerator are typically due to volatile fatty acids, so when a food goes bad, it discharges butyric acid, which is a nasty odor. We all know that bases neutralize acids, and baking soda or sodium bicarbonate is a base.
To remove odors, sodium bicarbonate reacts with butyric acid and forms sodium butyrate, which doesn’t have a smell as it is not volatile.
