If your freezer cooler has developed a bad smell, here are some steps you can take to get rid of the odor:
Remove all Contents: Empty the freezer cooler completely. If there are any expired or spoiled items, dispose of them properly.
Unplug the Freezer: For safety reasons, unplug the freezer cooler from the power source before cleaning.
Defrost the Freezer: If your freezer has a lot of frost buildup, it's a good idea to defrost it. You can do this by letting it sit with the door open until the frost melts away. You can also speed up the process by placing bowls of hot water inside the freezer to help melt the ice faster.
Clean with Soapy Water: Use a mixture of warm water and mild dish soap to clean the interior surfaces of the freezer. Wipe down all the shelves, walls, and drawers. Pay special attention to any spills or stains.
Baking Soda Solution: After cleaning, create a solution of 1 part baking soda to 3 parts water. Wipe down the interior surfaces with this solution, as baking soda can help neutralize odors.
Activated Charcoal or Coffee Grounds: Place a small bowl of activated charcoal or coffee grounds inside the freezer. Both of these substances are known for absorbing and eliminating odors.
Ventilation: Keep the freezer door open for a few hours to allow proper ventilation and to help dissipate any remaining odors.
Vinegar Solution: If the smell persists, you can try wiping down the interior with a mixture of equal parts water and white vinegar. Vinegar is effective at neutralizing odors.
Odor-Absorbing Products: Consider using commercial odor-absorbing products specifically designed for refrigerators and freezers.
Vanilla Extract: Dab a cotton ball or sponge with a few drops of vanilla extract and place it in the freezer for a pleasant scent.
Avoid Strong-Smelling Foods: In the future, try to avoid storing strong-smelling foods without proper containment in the freezer. Use airtight containers or double-wrap pungent items.
Regular Cleaning Maintenance: To prevent future odors, make it a habit to clean your freezer regularly and remove any spoiled or expired items promptly.
By following these steps, you should be able to eliminate the unpleasant smell from your freezer cooler. However, if the odor persists despite your efforts, there might be an underlying issue, and it's best to have the appliance checked by a professional technician.
