Empty the fridge, pull the drawers and shelves, and wash the box with baking soda in warm water. Then go after the smell where it actually lives: the puddle under the crisper, the drain hole at the back of the floor with its drip pan below, the folds of the door gasket, and the ice. A smell that survives a wipe-down has a reservoir.
That is the part almost nobody answers. The manufacturers and the big guides all explain how to clean a refrigerator; our own step-by-step is in how to clean your refrigerator. This post is the other half: why the smell is back in six or seven days, and what Miami does to make it worse.
“If the smell came back, you did not clean badly. You missed the reservoir.”
The four reservoirs
1. The puddle under the drawers
Crisper and deli drawers sit in a channel, and that channel is the most-skipped surface in the entire refrigerator: fruit juice, defrost water, something that used to be lettuce. Pulling the drawer and washing it accomplishes nothing if the channel underneath stays as it is. Drawers come out whole, the channel gets washed, and everything dries before it goes back — because water on top of an odor dilutes it for a day and hands it back the next.
2. The drain hole and the drip pan
At the bottom of the compartment, usually centered on the back wall at floor level, there is a hole about the width of a pencil. Defrost water runs down it into a shallow pan under the unit, near the compressor, where it is supposed to evaporate. It is the reservoir nobody cleans because nobody knows it is there: it clogs with crumbs and whatever spilled three months ago, the water stands, and the odor climbs back up the same hole it went down. Before you touch it, check your model’s manual — every manufacturer has its own instruction for clearing that drain and its own answer for whether the pan is reachable at all.
This is where Miami humidity collects its fee. A pan of water gives up moisture more slowly into air that is already damp, so what would evaporate on its own in a dry climate simply sits there in August. That is not a statistic or a measurement — it is drying physics, and it is why a pan in Kendall has a harder time than the same pan in Denver.
3. The gasket folds
The rubber gasket that seals the door is an accordion, and every fold holds crumbs, liquid and moisture. In a Miami home that door opens onto humid air twelve months a year and the cold edge condenses every time, so the folds here stay damp longer than they would in a dry climate — and a damp fold with crumbs in it is where dark spotting starts. Warm soapy water and an old toothbrush, fold by fold, dried at the end. A dirty gasket also seals worse, and a door that seals worse lets in more humid air — the same loop, again.
If what you are looking at is visible growth rather than a stain, stop. That is not a cleaning problem and we do not treat it as one: our Terms say we reserve the right to refuse or stop service where conditions are unsafe for our team — such as mold, infestation, biohazards, or abusive behavior, and that if we stop early for safety, a partial refund applies for the unworked portion. A cleaning visit is not remediation.
4. The ice, and anything porous
Old ice takes on freezer odor and hands it back in your glass. Dump the whole bin, wash it, and let the machine make fresh. The same goes for uncovered butter, bread, and any scratched plastic container: porous things absorb and then emit. If everything is clean and the smell is unchanged, throw out the first thing you open and have to sniff twice.
What baking soda does — and does not do
As a cleaner, baking soda dissolved in warm water does honest work: it cuts grease and leaves no scent, which is exactly what you want next to the butter. That is why it goes on the inside of the box and why bleach and perfumed cleaners stay out of food zones.
The open box on the shelf is a different claim. It is a household habit, not a tested product, and we are not going to tell you how much odor it removes or how fast — we have nothing to back that up with. Same for activated charcoal, coffee grounds and a cup of vinegar: where a product makes a claim, its label is the only honest source for what it does, and the label is what counts. What we can say from doing this for a living is that none of them substitutes for finding the reservoir. They are for what is left, not for what is still there.
And one distinction that matters in a kitchen: cleaning is not disinfecting. They are two different steps with two different purposes, and we keep them apart in cleaning vs. sanitizing vs. disinfecting instead of blurring them here.
What South Florida does to a refrigerator
June through November: the outage
Hurricane season runs June through November, and a refrigerator that spent hours without power is not the same job. Defrost water fills the pan at once, protein liquid runs into the drawer channel, and if the door stayed shut for days the odor settles into the plastic. What food stays and what goes is not our call and not this post’s: that belongs to public health guidance and to your appliance manual, not to a cleaning company. All we cover here is what to do with the box once you have decided.
The local rhythm, which is not spring
Our deep cleaning in Miami page puts it this way: most Miami homes benefit from a deep clean two to three times a year, because humidity, salt air, and year-round pollen mean buildup happens faster here than in drier climates. The fridge fits that same calendar with one local adjustment: do it before the season starts, while you still have power and time, and again once it ends.
In a building, the smell may not be yours
A Miami tower gives you more suspects than a house does. Before you strip the fridge again, check the disposal, the dishwasher filter, the sink trap, the trash cabinet and your floor’s trash-chute room. If the smell is all over the kitchen and not inside the refrigerator when you open the door, the fridge is the victim, not the cause.
What we do — and what we ask of you first
The fridge interior is an add-on with a published price: the Deep clean card on our services page lists “empty refrigerator $65 · refrigerator with food $85”. That $20 difference is exactly the emptying and restocking work, and it is why we ask you to empty it before we arrive: which food stays is your decision, and the team’s time goes further on the drawer channel and the gasket than on auditing your hot sauce.
The deep clean around it is its own service: a 4–6 hour visit with a 2-person team, 42 items verified by photo, a CleanCheck Report on eligible completed visits, and a 24h reclean guarantee. Appliance interiors, cabinet interiors and window cleaning remain separately priced unless your confirmed scope explicitly includes them, and areas behind or beneath appliances are cleaned only when safely accessible without moving installed or heavy appliances. We arrive with everything: vacuums, mops, and eco-friendly products by default, with fragrance-free options on request — which matters when you have just removed one smell and do not want it replaced with another.
The short version
Emptying, washing with baking soda and drying is half the job. The other half is four places: the channel under the drawers, the drain with its pan, the gasket folds and the ice. Find the reservoir and the smell does not come back on Thursday. And if the smell is all over the kitchen, the fridge was never the problem.
