How to Clean the Fridge and Get Rid of the Smell for Good

Every tip here is checked against the sources listed at the bottom.

An open, empty refrigerator with the glass shelves out on a towel, a bowl of baking soda water and a soft cloth on the counter, and an open box of baking soda on a shelf

The short answer

What works Throw out the food or spill causing the smell. Wipe the inside with 1 tablespoon of baking soda in a quart of warm water, and wash the shelves and drawers in warm, soapy water. Dry everything, leave the door open about 15 minutes, then set an open box of baking soda inside.

How long
The longest wait is letting cold glass shelves reach room temperature before you wash them, plus about 15 minutes of airing out. A stubborn smell can take 2 or 3 days with activated charcoal.
What it costs
A 1 lb box of Arm & Hammer Pure Baking Soda was $1.79 and a 14 oz Fridge-n-Freezer box was $1.59 at Target.com on November 6, 2026.
What you need
Baking soda, dish soap, warm water, soft cloths or a microfiber cloth, a cooler with ice packs and a trash bag.

Before you start: did the power go out?

If the smell started after a power outage, the food comes first. The FDA says to throw out refrigerated perishable food, like meat, poultry, seafood, milk, eggs and leftovers, that has been above 40°F for 4 hours or more. The FDA also says you cannot rely on how food looks or smells to tell if it is safe.

A closed fridge keeps food cold for about 4 hours, according to the FDA. A full freezer holds its temperature about 48 hours with the door closed, or 24 hours if it is half full.

Step by step

  1. Find the smell and throw it out

    Go shelf by shelf and drawer by drawer. Check dates, open containers and lift the crisper drawers to look underneath. Throw out anything spoiled or past its date, and bag it right away so the smell leaves the kitchen with it.

  2. Move the good food to a cooler

    Put everything you are keeping into a cooler with ice packs, as Whirlpool suggests. Wipe sticky jars and containers before they go back in later. Whirlpool also says to unplug the fridge or turn off the cooling before a deep clean.

  3. Take out the shelves and drawers, and let glass warm up

    Lift out the shelves and drawers, using both hands on glass shelves because they are heavy. Let cold glass sit on a towel until it reaches room temperature. Whirlpool says glass shelves may break from a sudden change in temperature.

  4. Wash the shelves and drawers

    Once the glass is room temperature, wash the shelves and drawers in warm water with a little mild dish soap. Rinse them and dry them with a soft cloth.

  1. Wipe the inside with baking soda water

    Stir 1 tablespoon of baking soda into a quart of warm water until it dissolves. That is the ratio both Texas A&M AgriLife Extension and Whirlpool give. Wipe the walls, the floor of the fridge, the inside of the door and the door gasket (the rubber seal), and gently lift the folds of the gasket to get the crumbs out.

  2. Rinse, dry and air it out

    Wipe everything again with a cloth dipped in clean water. Dry every surface completely with a lint-free towel. Then leave the door open for about 15 minutes so air can move through, as the University of Nebraska’s extension page advises.

  3. Put it back together and check the temperature

    Put the shelves and drawers back, plug the fridge in and return the food. Keep a thermometer inside, because the FDA says the fridge should be at or below 40°F.

  4. Set out baking soda to catch what is left

    Open a box of baking soda and stand it upright on a shelf. The Arm & Hammer Fridge-n-Freezer box is made for this: you take off the front and back panels and leave the top on. Its label says to change it every 30 days, and to write the date that is 30 days from opening right on the box.

When it will not work, and what to do instead

A strong smell can hang on after a good cleaning. Here is what to do next.

  • The smell is still there the next day. Check under and behind the drawers again, and wipe the gasket folds one more time.
  • It is still strong after that. With the fridge empty, set out trays of activated charcoal and run it for 2 or 3 days, as the University of Nebraska’s page advises. Texas A&M notes that activated charcoal soaks up smells faster than the charcoal you grill with, and that drug stores and pet supply stores sell it.
  • You do not have charcoal. The same Nebraska page lists trays of baking soda or clean kitty litter, or fresh ground coffee on cookie sheets, with the empty fridge running 2 or 3 days. Coffee can leave a light coffee smell that goes away after washing and rinsing.
  • Nothing works. If the smell has soaked into the insulation behind the walls, the Nebraska page says it needs a refrigerator technician, and Texas A&M suggests calling the manufacturer. Texas A&M also says that sometimes nothing can be done.

Be safe

  • When in doubt about food after an outage, throw it out. The FDA says to discard perishable food that has been above 40°F for 4 hours or more, and not to trust looks or smell.
  • Never put cold glass shelves in warm water. Let them reach room temperature first. Whirlpool says they may break from a sudden temperature change.
  • Skip harsh cleaners inside the fridge. Whirlpool says not to use window sprays, scouring cleansers, flammable fluids, cleaning waxes, concentrated detergents, bleaches or cleansers with petroleum products on the liners and gaskets, and to make sure any cleaner is bleach free and ammonia free.
  • One product at a time. If you also use vinegar, wipe it on its own and rinse before anything else. See the full never-mix chart.
  • Keep perishable food cold while you clean. Use a cooler with ice packs.

Why it works

Here is the thing about a fridge smell. Texas A&M’s odor guide starts with one plain step: remove the food. Only after that do you wash and set out baking soda.

After that, baking soda does the cleanup. It is a mild alkali (the opposite of an acid, like vinegar), and the American Cleaning Institute says it can act as a deodorizer inside refrigerators and freezers, where it absorbs odors from food.

Activated charcoal is the next step when baking soda is not enough. Texas A&M notes that it is extra dry and soaks up smells faster than the charcoal you grill with.

Most of us find the smell before we find the cause. You open the door, wrinkle your nose and start sniffing jars one at a time, and that is the right instinct.

A word from Denise

And then make it a habit. Wipe spills the day they happen, and change that box of baking soda every 30 days. Write the date right on the box, so you never have to guess.

Questions people ask

Does baking soda really absorb fridge smells?

It helps. The American Cleaning Institute says baking soda can act as a deodorizer inside refrigerators and freezers. Texas A&M’s guide still says to remove the food and wash first.

How often should you replace baking soda in the fridge?

Every 30 days, according to the Arm & Hammer Fridge-n-Freezer label. Write the date on the box.

How do you get rid of a fridge smell after a power outage?

First follow the FDA food rule: throw out perishable food that sat above 40°F for 4 hours or more. Then clean with baking soda water. If the smell lingers, run the empty fridge with activated charcoal or fresh coffee grounds for 2 or 3 days.

Can I wash cold glass fridge shelves in hot water?

No. Let them warm to room temperature first, because Whirlpool says glass shelves may break from a sudden change in temperature.
