The refrigeration appliance is dirty because of food that has leaked.
Small amounts of milk or orange juice can spill out and then drip into the drain at the back of the appliance. The drain is designed so that defrosted water evaporates in the defrost drip tray. If liquids like milk or orange juice get into the drain, this can result in a bad smell when the appliance is defrosted.
To neutralize the odor, pour an odorless mild cleaning agent into the drain.
Only use food-safe cleaning agents to clean the interior of the refrigeration appliance.
To avoid damaging the surfaces of the refrigeration appliance, do not use the following cleaning agents:
cleaning agents containing soda, ammonia, acids, or chloride
cleaning agents containing descaling agents
abrasive cleaning agents, such as scouring powder, scouring liquid, or pumice stones
cleaning agents containing solvents
stainless steel cleaners
dishwasher cleaners
oven sprays
hard, abrasive sponges and brushes, e.g., pot scourers
India rubber sponges
metal scrapers
