How to Permanently Eliminate Bad Refrigerator Odors

Deep Cleaning: The First Step to a Fresh Refrigerator

A deep clean is always the first step when you notice an odor. A quick surface wipe will not solve the problem because smells often come from hidden areas. Shelves, drawers, seals, and corners must be cleaned thoroughly to eliminate odor at the source.

It is recommended to clean your refrigerator thoroughly at least once every two months, or sooner if:

• A strange odor lingers even after airing.

• Food has spoiled following a long power outage.

• Spilled liquids, mold, or rotten food are discovered in drawers or corners.

Step-by-Step Cleaning

1. Remove all food and check it carefully

Empty the fridge completely. Place food in an insulated cooler to keep it cold. Inspect every item and throw away anything expired, moldy, or giving off a strong odor.

2. Unplug the appliance

Disconnect power before you begin wet cleaning or removing interior parts. This ensures safety and makes it easier to handle shelves and drawers.

3. Soak drawers and shelves

Put all removable parts in warm water mixed with dish soap or a little baking soda. Leave for 15–20 minutes, then scrub gently with a sponge to remove stains and lingering smells.

4. Wipe walls and hidden corners

Use a soft cloth with warm soapy water. Pay close attention to corners, folds, and spots where liquid may have collected. For stubborn stains, use a paste of baking soda and water and scrub gently.

5. Clean door seals and control panel

Rubber gaskets around the doors and the control area often trap food particles and moisture. Wipe thoroughly until clean.

6. Check vents and back coils

Use a soft brush or handheld vacuum to remove dust from air vents and the back of the refrigerator. This improves cooling and reduces moisture that can cause odors.

7. Dry parts completely

Let drawers and shelves air dry or wipe them with a clean towel before putting them back. Never reinstall them while wet, as this encourages bacteria and mold.

8. Reload food and restart

Place food back neatly, leaving gaps for air circulation. Plug the refrigerator in and set the temperature between 36°F and 39°F (2°C–4°C).

Causes of Refrigerator Odors

Cleaning alone is not enough if the root cause is ignored. Understanding why odors develop is the key to stopping them permanently.

Rotten food is the most common reason for refrigerator odors. A forgotten piece of cheese, old leftovers, or opened dairy products can quickly spread smells throughout the entire fridge. Regularly inspect food and discard anything questionable.

Spilled juice, soup, or even plain water that is not cleaned immediately can form sticky layers where bacteria grow. Uncovered food containers also release strong smells that spread easily, especially foods such as onions, garlic, or fish.

Moisture that collects under drawers or in corners creates the perfect environment for mold and fungi. These microorganisms not only cause odors but can also affect food quality. Blocked air vents reduce airflow, which makes the problem worse.

Quick surface cleaning often ignores areas such as door seals, vents, and bottom drawers. Residues left there for long periods become constant odor sources even if main shelves look clean.

Many modern refrigerators include air filters. If these are not cleaned or replaced, they can trap and release smells. Incorrect temperature settings, especially when set too high, also lead to faster spoilage and stronger odors.

Preventing Odors from Returning

A one-time cleaning will not keep the fridge fresh. Consistent habits are required.

Check all contents once a week. Throw away food that is expired, discolored, moldy, or has a strong smell. Acting quickly prevents odors from spreading.

Strong-smelling foods such as fish, cheese, or onions should be stored in sealed boxes or bags. Proper storage prevents odor transfer and keeps other food fresh.

Arrange food so older items are used before newer ones. Leave enough space between containers for airflow. A tidy fridge makes it easier to spot food before it spoils.

Keep the refrigerator between 36°F and 39°F (2°C–4°C). Higher settings encourage bacteria growth and faster spoilage. Use an internal thermometer to double-check, especially in summer.

If your fridge has an air filter, replace or clean it according to the manual. Wipe door seals and handles regularly to prevent dirt and bacteria buildup.

If odors remain after cleaning, unplug the appliance and leave the door open for a few hours. This refreshes the air inside.

Natural Ways to Keep the Fridge Fresh

You do not need chemicals to maintain freshness . Natural methods are safe and effective.

• Baking soda: Place an open container on a shelf. Replace every two to three months.

• Citrus slices: Lemon or orange slices add a light, clean scent. Replace weekly.

• Coffee grounds or activated charcoal: Both are excellent absorbers of strong odors. Place in a bowl or cloth bag.

• Essential oils: Cotton balls soaked in lavender, mint, or orange oil can be placed in a small ventilated container.

Tip: Use one method at a time. Mixing too many scents can cause an unpleasant combination. Replace natural fresheners regularly.

LG Technologies That Help Prevent Odors

LG refrigerators are designed with advanced features that protect freshness and reduce odors even during heavy daily use.

This system circulates cold air quickly and evenly across all shelves. It reduces humidity in corners and prevents odors from concentrating.

Fruit and vegetable drawers are equipped with humidity control. Adjusting the setting keeps produce fresher for longer and prevents odors caused by spoilage.

LG’s advanced compressor provides steady cooling without sharp fluctuations. Stable temperature prevents early food spoilage and reduces odor formation.

Some LG models include built-in filters that trap bacteria and odor-causing particles. Cleaning or replacing them regularly ensures lasting freshness.

Final Thoughts

Bad refrigerator odors are common, but they do not have to be permanent. By combining deep cleaning with smart storage habits, weekly checks, and the support of LG’s advanced technologies, you can enjoy a refrigerator that always smells fresh. Natural methods like baking soda or citrus slices can support your routine, while organized shelves and proper temperature settings keep food safe and tasting better for longer.
