Sometimes when a fridge loses power like this, no amount of scrubbing can get the smell out...been there done that. Between the 2 of us, we scrubbed that fridge everyday for almost a week with almost every chemical cleaning product we could get our hands on.

Finally after talking to an appliance repair person, he told us the smell was from bacteria growth in the cooling system (vents) in the fridge and freezer compartments. Short of dismantling the fridge completely, no amount of cleaning will kill bacteria that you cannot get to. The cost and time to dismantle, clean then re-assemble the fridge was still no guarantee that all bacteria had been killed.

In the interests of our health, we replaced the fridge and recycled the original.
