Strong unpleasant smell inside the refrigerator even after removing spoiled food.

Deep cleaning:

• Unplug the fridge and remove all food, shelves, and drawers.
• Wash all removable parts with warm water and mild detergent; rinse and dry.
• Clean interior surfaces with a solution of baking soda and water (about 2 tablespoons per liter).

Clean drain and hidden areas:

• Flush the defrost drain hole with warm water using a syringe or turkey baster.
• Clean around door gaskets and folds where mold can grow.

Odor absorption:

• Place an open box of baking soda or activated charcoal in the fridge to absorb residual odors.

Air filter (if fitted): Replace any internal air filter cartridge with a Finlux-compatible deodorizing filter.
