Open the door, get hit by a whiff of something sour, and suddenly your morning yoghurt seems a lot less appealing. If you’re wondering how to get rid of smell in fridge problems for good, the good news is that you rarely need expensive gadgets or harsh chemicals — just a methodical clean and a few clever natural deodorisers. In this UK guide, we’ll walk through what causes the pong, how to clear it fast, and how to stop a smelly fridge coming back.
Why does my fridge smell?
Before you can banish the odour, it helps to understand where it’s coming from. A fridge usually smells for one (or several) of these reasons:
- Spoiled food — forgotten leftovers, off milk or wilting veg at the back of a drawer
- Spills and crumbs — sauce, juice or meat juices that have seeped into shelves
- Dirty door seals — the rubber gasket traps residue, mould and mildew-like smells
- A clogged drip pan or drain — standing water under the fridge breeds bacteria
- Strong-smelling foods — uncovered cheese, fish, onions or garlic sharing the air
In short, lingering odour is almost always a sign of bacteria feeding on organic matter somewhere inside. Find that source, and you’re halfway to a fresh fridge.
How to get rid of smell in fridge: step-by-step deep clean
A proper deep clean is the single most effective fix. Set aside 30–45 minutes and work through these steps.
1. Empty it and bin the culprits. Unplug the fridge, take everything out and ruthlessly discard any spoiled food, anything past its date or anything you can’t identify. Pop perishables in a cool bag while you work.
2. Wash the interior. Remove all shelves and drawers and wash them in warm, soapy water. Wipe the inside with a 50/50 mix of warm water and white vinegar, which is mildly acidic and naturally neutralises odours and mildew. For stuck-on grime, a paste of baking soda and water lifts it without scratching.
3. Don’t skip the door seals. Run a cloth dipped in warm soapy water along every fold of the rubber door seals (the gasket). This is the spot most people miss, and it’s a classic odour trap.
4. Clean the drip pan. Slide out the drip pan from underneath the fridge and wash it with warm water and a little washing-up liquid — stagnant water here causes a musty smell that no amount of interior cleaning will fix.
5. Dry and air it out. Dry every surface with a clean towel, then leave the door open for 15 minutes to an hour before switching it back on. If the smell was strong, leaving it open overnight helps even more.
If your freezer is part of the problem, it’s worth pairing this with a proper deep clean of the freezer and, if it’s frosted up, a full defrost of the fridge freezer so you can reach every corner.
How to remove smell from fridge naturally
Once your fridge is spotless, a natural deodoriser will mop up any lingering odour and keep things fresh. Here’s how the most popular options compare.
| Natural deodoriser | How to use it | Replace every |
|---|---|---|
| Baking soda | Open box or shallow bowl on the middle shelf | 1–3 months |
| Activated charcoal | Small bowl at the back of the fridge | 2–3 months |
| White vinegar | Bowl with a vinegar-soaked cloth, left 24 hrs | As needed |
| Lemon | Halved lemon or slices in a bowl | 1 week |
| Coffee grounds | Dry grounds spread on a plate | 1–2 weeks |
| Oats | Uncovered tub of uncooked oats | 2–4 weeks |
Baking soda is the classic for good reason — it neutralises acidic odour molecules rather than just masking them. If you’d like to know exactly what you’re working with, our explainer on whether bicarbonate of soda is the same as baking sodaclears up the confusion. Activated charcoal is even more powerful for stubborn pongs, while a bowl of coffee groundsor fresh lemon leaves a pleasant scent behind. These are all staples of natural cleaning products you probably already have in the cupboard.
How to get rid of a bad smell in fridge fast
Need a quick fix before guests arrive? Pull out and bin anything obviously off, wipe the shelves with a cloth dampened in white vinegar, and sit a bowl of baking soda or coffee grounds inside. Leave the door shut for an hour and the worst of the odour will lift. For a deeper but still speedy refresh, the trick used by food safety experts is to wash the interior with warm water and baking soda, then leave the door open for 15 minutes to let fresh air circulate. White vinegar is a brilliant all-rounder here — the same white vinegar cleaning method works across the whole kitchen.
Why does my fridge smell bad even after cleaning?
Frustrating, isn’t it? If you’ve scrubbed everything and the odour persists, one of these is usually to blame:
| Hidden cause | What to check |
|---|---|
| Odour in the insulation | Strong smells can soak into the plastic lining — repeat with baking soda or charcoal over several days |
| Dirty evaporator coils | Located at the back of the freezer; vacuum off dust and dirt |
| Blocked drain hole | A clogged drain at the back causes a musty, damp smell |
| Lingering gasket residue | Re-clean the door seals thoroughly with soapy water |
A smell coming from the back of the fridge in particular often points to the evaporator coils or drain rather than anything you’ve stored. Give those a clean and the problem usually clears within a few days.
How long does it take for fridge smell to go away?
It depends on how deeply the odour has set in. A light smell vanishes within a few hours of cleaning and adding a deodoriser. A strong, set-in smell (say, after a power cut spoiled a freezer full of food) can take five to six days of running the fridge with bowls of baking soda, charcoal or crumpled newspaper inside before it fully disappears. Patience and a fresh deodoriser usually win.
How to keep your fridge smelling fresh
Prevention beats cleaning every time. To stop a fridge smelling in the first place:
- Keep all foods tightly wrapped or covered, especially strong-smelling ones
- Wipe up spills the moment they happen
- Give the fridge a quick deep clean roughly once a month
- Keep a permanent box of baking soda on a shelf and swap it every few months
- Stay organised so nothing gets forgotten and goes off — our fridge organisation tips make this effortless
It’s also worth remembering that odour can travel between appliances, so keeping your dishwasher clean and your microwave fresh helps the whole kitchen smell better.
When to call in the professionals
If you’ve worked through every step and a deep, persistent odour remains — or if a power cut has left you with a serious spoiled-food situation — it can be worth booking a professional clean. Professionals can tackle a full kitchen refresh (the same way they’d handle a smelly washing machine) so you can hand over the grim jobs and enjoy a fresh-smelling home.
FAQ
How do you deodorize a refrigerator?
Clean it thoroughly first, then place a deodoriser on the middle shelf — an open box of baking soda, a bowl of activated charcoal, or fresh coffee grounds. These absorb and neutralise odour rather than masking it. Replace them every one to three months.
What kills a bad smell in the fridge?
White vinegar is one of the best, because its acidity destroys the mildew and bacteria causing the smell. Wipe the interior with a 50/50 vinegar-and-water solution, then follow up with baking soda to absorb anything left behind.
How do I find the source of a fridge smell?
Check the easiest culprits first: look for spoiled food, hidden spills, and standing water. Then inspect the door seals and the drip pan underneath — both trap residue that smells. If the odour comes from the back, suspect the evaporator coils or drain.
Why is my fridge letting off a nasty smell?
Usually it’s bacteria feeding on spilled or spoiled food, an uncovered strong-smelling item, or a dirty gasket and drip pan. Occasionally it’s a more serious fault like mould in the insulation or dirty coils.
Can I use lemon to remove fridge smells?
Yes — lemon is a great natural option. Wipe shelves with lemon juice on a cloth, or leave halved slices in a bowl for a few hours up to a week. It neutralises odour and leaves a clean, fresh scent.
How often should I clean my fridge to prevent smells?
A quick wipe-down weekly and a proper deep clean about once a month keeps odours from ever building up. Swapping your baking soda every few months tops up the freshness between cleans.
Is there a smell absorber for the fridge ?
Yes, you can find several effective options like the Croc Odor or Fridge Ninja that use activated charcoal to trap nasty niffs. These handy absorbers are much more powerful than baking soda and keep your shelves smelling “easy peasy lemon squeezy” fresh for months.
What’s the most effective refrigerator odor remover ?
According to recent consumer reviews and testing, the most effective refrigerator odor remover for tough smells is often a dedicated deodoriser like the Fridge Ninja or Purriko, which use activated charcoal or catalytic decomposition to neutralise foul smells in just a few hours. While traditional baking soda is a reliable budget choice, these advanced absorbers are significantly more powerful at tackling stubborn fish or garlic odours. For a long-term, “fit and forget” solution, many UK households now opt for rechargeable ionic purifiers or stainless steel deodorisers that can last up to 10 years without needing a refill.
