Safety: Unplug the refrigerator before deep cleaning. Use non-abrasive, food-safe cleaners.

Steps:

  • 2. Clean interior: Wash all surfaces with a solution of warm water and mild detergent or baking soda. Rinse and dry thoroughly.
  • 3. Clean drain channel: Flush the refrigerator drain channel with warm water and a small amount of disinfectant. Ensure it flows freely to the drain pan.
  • 4. Clean drain pan: Access the drain pan above the compressor and clean it with warm soapy water. Dry completely.
  • 5. Deodorize: Place an open box of baking soda or a refrigerator deodorizer inside to absorb residual odors.

Tip: Avoid storing uncovered strong-smelling foods and clean spills promptly to prevent odor buildup.
