Refrigerator interior has a strong unpleasant odor that persists after basic cleaning

Safety first: Unplug the appliance before deep cleaning and avoid harsh chemicals that can damage plastics.

• Remove all contents: Discard spoiled food. Remove shelves, drawers, and door bins for separate cleaning.
• Clean surfaces: Wash interior with a solution of mild detergent and warm water, then wipe with a mixture of baking soda and water.
• Clean drain: Flush the internal drain hole with warm water and a small amount of mild disinfectant, then rinse.
• Clean gaskets: Gently scrub door gaskets with warm soapy water and a soft brush to remove mold or residue.
• Air out: Leave doors open for several hours (with fridge unplugged) to ventilate, using towels to catch condensation.
• Use odor absorbers: Place open boxes of baking soda or activated charcoal inside for several days.
