Fridge Smells Even After Cleaning
A fridge that still smells after cleaning is usually still holding the source: something spoiled hiding in a drawer, film growing in the drain hole, or odor soaked into the folds of the door gasket. Absorbers help with the air, but they cannot fix a source that is still in there making the smell.
The short answer
Find and remove the source first, wash the drawers and gasket folds, clear the drain hole, then put a fresh box of Arm & Hammer Fridge-N-Freezer in to handle the air that remains. It holds 4.8 stars from 4,164 ratings on Target (November 2026). Baking soda neutralises acid odors. It does not fix a rotting source, which is why changing the box alone so often changes nothing, and why the order of the steps on this page matters more than the box.
Why does this happen?
Refrigerator odor is rarely in the air itself; it is continuously supplied by something in the fridge. The usual causes are a spoiled item pushed to the back of a drawer, liquid from meat packaging pooled under a crisper, residue in the folds of the door gasket, and the drain hole at the back, where a film of microbes can grow in a permanently damp channel and fill the whole cabinet with smell. Wiping shelves does not reach most of those places, which is why a cleaned fridge can smell uncleaned within a day.
Baking soda's role is real but narrow: sodium bicarbonate neutralises the acidic compounds that make up much of food odor, working on the air that passes over the exposed powder. It has no effect on the source producing those compounds, and a saturated old box has little capacity left. That explains the common complaint that a fresh box did nothing. Remove the source, clean the hidden places, then let fresh soda work on the air. Each part of the job then does what it can actually do.
The fix, in order
The steps are ordered cheapest first. Stop at the one that solves it and skip the rest; the product is there only for where the free steps run out.
Free step
Hunt the source before touching any freshener
Empty one shelf or drawer at a time and check the backs and undersides, where spills and forgotten items hide. Sniff the crisper drawers empty, check under them for pooled liquid, and inspect anything in door bins with a broken seal. Dispose of anything questionable. No absorber works better than simply removing what is rotting.
Free step
Scrub the hidden places: gaskets and drain hole
Wash removable drawers and shelves in warm soapy water and dry them fully. Wipe the door gasket folds, where residue collects out of sight, and clear the drain hole at the back of the cabinet with a soft brush or pipe cleaner and warm water, since a blocked, filmed drain is a classic lingering source.
The product step
Set a fresh box of Arm & Hammer Fridge-N-Freezer
With the source gone and surfaces dry, place a fresh box with its vent panel open where air circulates, rather than wedged behind food. Date the box with a marker so you replace it by the date, not by guessing, and replace the freezer box at the same time if your fridge uses both compartments.

Habit step
Keep the replacement and leftovers rhythm
Replace the box roughly once a month in a busy fridge. It slowly loses its ability to absorb smells as it fills up. When you change it, also go through your leftovers: label containers with dates, move older food to the front, and throw away anything you cannot identify before it becomes the next hidden source of smell.
The evidence, in tiers
Tier 1 · The method
Sodium bicarbonate neutralising acidic odor compounds is basic, settled chemistry, and fridge makers' own care guidance points owners at the same hidden sources, drawers, gaskets, and the drain channel, when odor survives a surface clean.
Tier 2 · This product
Arm & Hammer Fridge-N-Freezer holds 4.8 stars from 4,164 ratings on Target (November 2026), and 4.8 to 4.9 stars across Home Depot listings with roughly 5,500 to 6,100 reviews (November 2026).
We have not spoiled food for this guide. The source first sequence follows the drain and gasket mechanism and standard fridge care guidance.
Tier 3 · What owners report
Owners report the familiar two camps: households where a fresh box on a clean fridge keeps the air neutral for weeks, and households where boxes changed nothing until a spoiled item or a filmed drain hole was found behind a drawer. The second camp's stories are the reason this page cleans first and absorbs second.
The alternatives, conceded where they win
| Option | What it is | The honest verdict |
|---|---|---|
| Arm & Hammer Fridge-N-Freezer Baking Soda | Neutralises acidic odors in the fridge air | The pick for the air side of the job: cheap, food safe, widely stocked, and honest about its limits; it finishes a clean fridge rather than substituting for cleaning one. |
| A bowl of ordinary baking soda | The same chemistry without the fridge format | Wins on price per ounce if a kitchen box is already open, and the chemistry is the same; it loses on format, because the vented fridge box exposes more surface, stands stably among food, and carries the replacement reminder the loose bowl never gets. |
| Charcoal fridge fresheners | Adsorb odors onto a carbon surface | Best for some households because it lasts longer between changes and works on odors that are not acidic. It loses on cost, and it has the same limit as everything in this table: no freshener of any kind fixes a source that is still rotting in a drawer. |
The honest price comparison
The honest comparison is a service visit or, at the extreme, replacing a fridge that was never broken, against an afternoon of drawer and drain cleaning and a box that costs very little. Persistent odor is almost always a source problem, and finding the source costs nothing but looking properly.
Where it falls short
The weaknesses below come from the product's own review record, the same record the recommendation rests on.
- It cannot fix a rotting source, and used alone on a dirty fridge it will seem to do nothing, which is the most common complaint about it.
- Its capacity fades quietly, so a box left for many months does nothing. Replacing it regularly is part of using the product, not an extra sale.
- It works on acidic odors in the air near it, so a large, packed fridge may need the source cleaned and the box placed where air actually moves.

Questions people ask next
I changed the box and it still smells. Why?
Because the box treats air, not sources. If something spoiled is hiding in a drawer, liquid has pooled under a crisper, or the drain hole is filmed over, the odor is being produced faster than any absorber can neutralise it. Clean the hidden places first, then judge the box.
Where exactly is the drain hole?
On most fridges it is a small hole in the channel at the back of the fresh food compartment, below the cooling vents. Water from defrost cycles drains through it, and the damp channel grows odor film. Clear it gently with a soft brush and warm water.
How often should the box be replaced?
Roughly monthly in a busy family fridge is the usual rhythm, sooner after a major spill or a spoiled food incident. Writing the date on the box when you install it turns the decision into a quick look instead of a guess.
Can I use the old fridge box for anything else?
Yes, spent fridge soda is commonly poured down a sink drain followed by hot water, or used for light scouring jobs. Do not move a used fridge box into baking; once it has lived in the fridge it stays a cleaning product.
