  1. Your first Vinegar solution ends with “the course”and looks cut off as to it’ ending.

    How long do you let the vinegar sit with the door closed?

    Really like your suggestions, had freezer given to me which had a rotten fish on the bottom self that had been thawed out for quite some time. Maggots and plenty of maggot eggs.

    Hosed iit out , sprayed with bleach soliton and have tried charcoal, baking soda, and some coffee grounds and still have a rotten smell but it is better. Will try the vinegar next.

    An appliance part store here in town told me the repairmen he knew use vinegar douche when working on units which next to be deodorized. Might try that if the other things on the list don’ work

    1. Bought a deep freeze for my daughter from a friends friend. Got it home thinking nothing of it and opened it up to the most horrible shrimp smell. I scrubbed it out with soft scrub with bleach and it took some of it out. So then I used bleach and water literally leaving bleach on the bottom of the freezer for hours. went out and cleaned it all out and washed it again with hot rinse water. Opened it up this morning and I can still smell the shrimp odor. not so bad but it is still there. Tried the vinegar, coffee…ect…I think mine is to gone into the walls of the freezer. Figured bleach would do it and I mean I used alot of bleach. Let me know if you find anything.

  2. I had a rotten meat odor in my deep freezer, I mixed half cup fresh squeezed lemon juice, half cup vinegar and quarter cup water, I sprinkled the freezer with baking soda then sprayed all sides with the lemon vinegar solution and left the freezer closed for few days, then I wiped it clean again. Now it smells fresh and clean again.

  3. Your comments on getting rid of the fish smell works only if you can reach the surface, but how do you really get the smell of fish if it’s in side the frig. The smell of fish, I do not know how it got there is coming out of the freezer exhaust vent where the fan blows the smell right into your face the minute you open the freezer door. Is there any suggestion on how to spray or put something down the exhaust vent to get the smell out. Any help to get rid of the nasty fish smell is appreciated. Send any information that would help. Thank you very much for any helpful suggestions. Sincerely a devoted person to a clean environment.
