Checking the freezer contents regularly and removing stale or spoiled food helps maintain hygiene and prevents freezer odors. However, this checking is overlooked or postponed many times. Food left in the back of the trays or where it cannot be reached easily is ignored and overstays its life in the freezer, causing it to go bad.

When stale food leaves its traces in the freezer, just pulling out the packet or container of the food will not get rid of the odor. The bacteria might have spread to the whole freezer and its contents if they are not stored in airtight containers. The gasket lining or the water lines could be carrying particles or liquids of the spoiled food and will have to be thoroughly cleaned.

• Regular cleaning
  The freezer interiors have to be wiped clean at least once in 3 months. Before cleaning, empty the freezer and switch it off. After it thaws, remove the water that collects, and repeat this cleaning with a sponge or soft cloth until all the dampness is gone.
• Things to use for cleaning the interiors of the freezer
  Clean the sides and shelves with a mixture of warm water and vinegar. Soak all the bins in soap and water and then clean them thoroughly. If using commercial cleaning liquids, ensure that they are mild or dilute them with water.
  Use a cleaning liquid to spray the interiors of the freezer, and wipe it clean after some time. After that, wipe with clear water sponge. Avoid scrubbing roughly as it may cause the linings or plastic coating to crack or peel. Dry the freezer thoroughly before plugging it in. Also, dry all the shelves and trays properly before putting them back in the freezer.
• Cleaning mold out of the freezer
  Mold forms in damp areas and spreads if the freezer is inactive. Once mold forms, the freezer has to be cleaned thoroughly. Using a cup of vinegar mixed with 3 cups of water and a few drops of dishwashing soap is a good tip to banish the unpleasant freezer odor and prevent mold formation. Dry the freezer properly before switching it on again, and place food only after ensuring that the mold is completely removed.
• Proper storage of food
  One of the most important tips to banish or prevent freezer odors is to store food in airtight containers or bags to seal the odor of different foods within its packing. This prevents it from contaminating other food items in the freezer, and it also keeps the food fresh for a longer time.
• Natural odor absorbents
  A helpful tip is to place some natural odor absorbers like lime, coffee, and baking soda inside the freezer to banish odor and prevent it from spreading.
• Maintaining the correct temperature in the freezer
  The correct temperature should be maintained to help keep food fresh and banish freezer odors.
