Getting a Smell Out of Fridge/Freezer

Ball up a ton of newspaper and shove it in there everywhere you can fit it then remove it. Also can wet a pan of charcoal and let it sit.

Coffee grinds helped get boiled crawfish smell out of mine

Is there an air filter in there? Some of the newer ones do.

If not make sure you spray down the top of the fridge inside the cooling area because the smells sometimes linger up there.

The other spot I’ve run into was the tracks where the produce and cheese trays roll. Juice and debris can get into those hard to reach areas and it’s really tough to clean them depending on how they are setup.

Next step would be putting baking soda in the back opened to absorb steam some of the smell.

+1 on the charcoal. Just a few briquettes in an open zip lock back usually does the trick for me

What’s the point of vinegar and baking soda? You are left with neither. The reaction yields a salt, water, and carbon dioxide. Maybe the carbon dioxide neutralizes odor??

Don't know about your refrigerator/freezer, but mine has a plastic tray underneath it and it will catch the occasional drip from the auto defrost cycle and it can often dry up and stink.

I had this issue a few months ago and it smelled like rotten shrimp. I put a rag on a stick to access the tray with hot water to loosen the dried on crap and then hit it with some pine oil to kill the smell. It worked.
