Throw out the spoiled food first, then take out the shelves and drawers and wash them in hot, soapy water. Wash the inside, including the door gasket, with baking soda and water, then let it air out. Still smelly? Put activated charcoal, baking soda or fresh coffee grounds inside and let the empty fridge run for 2 or 3 days. The USDA warns you may have to repeat this. And never mix bleach and vinegar.

Step 0: Be Ruthless With the Food
A fridge that stinks usually means something in there went bad, maybe after a power outage, maybe just a forgotten container at the back. The FDA’s rule is short: anything that looks or smells suspicious should be thrown out. Bag it, tie it, and take it straight outside so the smell doesn’t move to your kitchen bin.
After a power outage, smell isn’t a good test the other way around either: food can make you sick without smelling bad. For a power outage, the FDA says to throw out perishable food such as meat, poultry, fish, milk, eggs and leftovers that has been above 40°F for 4 hours or more. (The USDA’s general refrigeration rule is stricter: above 40°F for more than 2 hours, don’t eat it. More in what temperature your fridge should be.)
My tip: while the fridge is empty, put the food you keep in a cooler with ice packs. Cleaning takes longer than you think.
The Deep Clean, Step by Step
This is the method Nebraska Extension gives, based on USDA advice:
- Take everything out that comes out: shelves, crisper drawers, ice trays.
- Wash them in hot water with dish detergent.
- Sanitize them: rinse with 1 tablespoon of regular unscented liquid chlorine bleach per gallon of water. Open a window, follow the label on the bottle and your fridge maker’s cleaning instructions, and mix the solution fresh (the CDC says to make diluted bleach new each day).
- Wash the inside of the fridge and freezer with hot water and baking soda, including the door and the rubber door gasket. Texas A&M gives an amount: 1 tablespoon of baking soda per quart of water.
- Rinse the inside with the same bleach solution.
- Air it out: leave the door open for about 15 minutes. The USDA’s own list says to let it air out for several days if you can.
The gasket matters. The USDA specifically says to scrub the gaskets, shelves, sides and door. Spilled juice loves to hide in the folds of that rubber seal. An old toothbrush helps (my tip).
Safety: What Not to Use
- Never mix bleach with vinegar, or with any other cleaner. The CDC says never to mix household bleach with other cleaners or disinfectants. Poison Control explains why: bleach plus an acid such as vinegar makes chlorine gas, and bleach plus ammonia makes chloramine gas. Use the vinegar method or the bleach rinse, on different days, and rinse with plain water in between (my advice).
- Air and protection. The CDC says to make sure you have good ventilation when using bleach indoors (open windows and doors), to follow the label, and to check whether you need gloves or eye protection.
- No harsh cleaners. The USDA says to avoid solvent cleaning agents, abrasives and cleansers that can leave a chemical taste in food or ice cubes, or damage the inside of the fridge. Follow your fridge maker’s cleaning instructions.
- Unplug before deep work if your manual says so. Texas A&M unplugs the fridge for the charcoal method.
Smell Still There? Try These (One at a Time)
Spoiled-food smells can soak into plastic. The USDA says these steps may have to be repeated. Here’s what the USDA and two university extensions suggest, roughly from easiest to slowest:
| Method | How | How long |
|---|---|---|
| Vinegar wipe | Wipe the inside with equal parts vinegar and water (USDA). Texas A&M uses 1 cup of vinegar per gallon. | Let it dry |
| Activated charcoal | Trays or pans of activated charcoal on the shelves or bottom. Texas A&M says it absorbs odors faster than grill charcoal; replace it if the smell stays. | 2 to 3 days (Nebraska), several days (Texas A&M) |
| Baking soda | Sprinkled loosely in the bottom or in an open container (USDA), or on trays (Nebraska). | 2 to 3 days, fridge running empty |
| Coffee grounds | Fresh grounds on cookie sheets or in an open container (USDA, Nebraska). A slight coffee smell may stay but washes off. | 2 to 3 days |
| Newspaper | Pack the shelves with crumpled newspaper and set a cup of water on the top shelf (Nebraska). Slow, but Nebraska says it works on strong odors. | 5 to 6 days |
| Vanilla | A cotton swab soaked in vanilla, in the freezer, door closed (USDA). | 24 hours, then sniff |
| Store-bought odor absorber | Follow the maker’s instructions (USDA). | As labeled |
When the Smell Won’t Leave
If a fridge stood closed with spoiled food for days, the smell can get into the insulation behind the plastic walls. Nebraska Extension says drippings from meat or fish can leak in there, and that a technician may have to remove the liner and replace the insulation. Texas A&M says to contact the manufacturer, and adds honestly that “sometimes nothing can be done.”
My advice: that’s the moment to ask whether a repair is worth it or a new fridge makes more sense, before you spend another week sniffing shelves.
Keep It From Coming Back
- Open box of baking soda on a shelf, the USDA’s everyday tip for keeping the fridge smelling fresh.
- Cover your food. The USDA says covering food also stops it from picking up odors from other food.
- Wipe spills right away with hot, soapy water (USDA). The FDA adds that cleaning the fridge regularly helps reduce the growth of Listeria.
- Do a weekly clean-out of food that’s past its time (USDA). Where things go so they don’t get lost at the back: where to put food in your fridge.
- Keep the fridge cold enough. 40°F or below: how to check it.
Frequently Asked Questions
What absorbs bad smells in a fridge?
Activated charcoal, baking soda and fresh coffee grounds, according to the USDA and Nebraska Extension. Put them in open containers or on trays and let the empty fridge run for 2 or 3 days. For everyday freshness, the USDA suggests an open box of baking soda on a shelf.
How do I get rid of a rotten meat smell in my fridge?
Throw out the meat, remove and wash the shelves and drawers, wash the inside and the door gasket with hot water and baking soda, rinse with a sanitizing solution of 1 tablespoon unscented liquid chlorine bleach per gallon of water, and air it out. If the smell stays, use activated charcoal for a few days. If juice leaked into the insulation, Nebraska Extension says a technician may be needed.
Can I use vinegar and bleach to clean my fridge?
Never mix them. The CDC says not to mix bleach with any other cleaner, and Poison Control explains that bleach plus vinegar makes chlorine gas. You can use one method, rinse with plain water, and use the other on another day, with the windows open.
How long does it take to get a smell out of a fridge?
It depends on how strong the smell is. For strong spoiled-food smells, Nebraska Extension’s methods take 2 to 3 days (charcoal, baking soda, coffee) or 5 to 6 days (newspaper), and the USDA says you may have to repeat them.
