How to eliminate bad odors from inside the refrigerator?

 

Empty and Inspect Your Refrigerator

 

First step in eliminating bad odors from your refrigerator is to remove all items. Check expiration dates and discard any spoiled or questionable foods, leftovers, or beverages. Inspect thoroughly to identify stains, mold, or spills. Sometimes odors originate from forgotten produce or spillage that has hardened onto surfaces. Removing these items and cleaning thoroughly helps immediately reduce unpleasant odors.

 

Unplug and Defrost if Necessary

 

If odors persist after removing food items or if you spot ice buildup, unplugging your refrigerator and allowing it to defrost can help eliminate built-up odors caused by moisture and ice accumulation. If you live in warmer climates—such as Nashville—defrosting can be quicker and ensuring your appliance is completely dry afterward is important to prevent bacteria and odor recurrence.

 

Clean Interior Surfaces with Natural, Household Products

 

Cleaning thoroughly and regularly is key to keeping odors away. Use mild detergent and warm water or a solution made from vinegar and water to thoroughly clean all interior surfaces. Vinegar is especially effective as a natural disinfectant and odor neutralizer.

• Mix equal parts water and white vinegar.
• Clean shelves, drawers, door seals, and walls.
• For tougher stains or residue, sprinkle baking soda onto a moist sponge or cloth and gently scrub.
• Rinse thoroughly with clean water and dry all surfaces well before placing items back.

 

Use Baking Soda or Activated Charcoal to Absorb Odors

 

After thoroughly cleaning your refrigerator, using odor absorbers can ensure freshness. Baking soda and activated charcoal can naturally absorb unpleasant odors.

• Place an open container or box of baking soda on a shelf towards the back of the refrigerator. Replace this every 30 days.
• Alternatively, activated charcoal packaged specifically for refrigerators is widely available and highly effective at odor removal. Simply place activated charcoal in a small bowl or breathable bag in various areas inside the fridge. Replace or refresh monthly.

 

Consider Natural Odor Neutralizers

 

If you prefer a pleasant aroma, certain household items can also help neutralize odors naturally.

• Freshly ground coffee placed in an open container absorbs lingering odors and leaves a pleasant scent behind.
• Lemon slices in a bowl can provide a fresh citrus fragrance while also helping neutralize odors.
• A few drops of vanilla extract on a cotton ball placed inside the fridge can leave a subtle, pleasant scent.

 

Maintain Appropriate Refrigerator Temperature

 

Maintaining the correct temperature in your refrigerator (ideally between 35–39 degrees Fahrenheit or 1.7–3.9 degrees Celsius) helps inhibit bacterial growth that can cause unpleasant odors. Regularly check thermostats to ensure proper cooling.

 

Regularly Check and Clean Drip Trays or Drain Pans

 

A commonly overlooked source of refrigerator odors comes from drip trays or drain pans located at the bottom or back of the appliance. Regularly cleaning and emptying these trays prevents bacteria and mold growth, especially important in humid areas like St Louis during certain seasons.

 

Seal Odorous Foodairtightly Before Placing in Refrigerator

 

Properly sealing meal leftovers, pungent cheeses, garlic, onions, or other odorous foods ensures the scents remain inside containers and do not circulate throughout your refrigerator. Airtight storage containers or resealable plastic bags effectively prevent odors from escaping into a clean refrigerator.

 

Check and Replace Refrigerator Filters

 

Some refrigerator models have built-in air filters or water filters. Regular replacement of these filters, according to the manufacturer recommendations (typically every 6 months), can significantly reduce odor-causing bacteria and improve your refrigerator's overall freshness.

 

Develop a Regular Cleaning Schedule

 

To prevent bad odors from reoccurring, establish a routine cleaning schedule—ideally once every month—coupled with weekly quick checks for spoiled food items or spills. A consistent practice of regular maintenance goes a long way in keeping your refrigerator fresh and odor-free.
