How to Clean Your Refrigerator and Remove Odour

Why Fridges Develop Odours

A refrigerator is a closed, cool, humid box packed with food, so smells build up naturally over time. Cut onions, leftover curry, ripe fruit, and open packets all release aromas that mingle and cling to the cold surfaces. Small spills that dry unnoticed, and food pushed to the back and forgotten, are usually the real culprits behind a persistent bad smell.

Regular cleaning is not just about odour, though. Storing food at the right temperature and keeping surfaces clean reduces the risk of spoilage and foodborne illness, a point stressed in food-safety guidance from the FSSAI. A clean fridge also runs more efficiently, because a crowded, grimy interior blocks the flow of cold air and makes the compressor work harder than it should.

Empty and Sort First

Start by clearing the fridge so you can clean and inspect everything properly.

1. Take out all the food and place it on the counter, grouping similar items together as you go.
2. Throw away anything expired, spoiled, or forgotten at the back of the shelves.
3. Wipe sticky jars and bottle bases before they go back in, so the shelves stay clean longer.
4. If you have many perishables, keep them in a cooler bag or a bowl of ice while you work.

This is the perfect moment to take stock of what you actually have, which cuts down on waste and double-buying. A quick sort every couple of weeks stops the fridge from becoming a graveyard of half-used packets and mystery containers. You will be surprised how much space you free up simply by clearing out what is past its best.

Work quickly during this stage so perishables do not sit out too long, especially in warm weather. If you plan to do a thorough clean, pick a time when the fridge is fairly empty, such as just before your weekly grocery run. That way you have less to shift around and fewer items to keep cold while you scrub.

Cleaning Shelves, Drawers, and Seals

Now clean the interior properly, working from top to bottom so any drips fall onto surfaces you have not yet done.

Shelves and drawers

Remove the glass shelves and vegetable drawers and wash them in the sink with warm water and dishwash liquid. Let glass shelves reach room temperature before washing so they do not crack from a sudden change in temperature. Dry them fully before refitting, since trapped moisture encourages mould.

Interior walls and the door seal

Wipe the inner walls with a cloth dampened in a mild baking-soda solution, which cleans and deodorises without leaving chemical smells near your food. Pay special attention to the rubber door gasket, where crumbs, mould, and spills love to hide. Clean it gently with an old toothbrush, as a clean seal also closes better and keeps the cold in.

While the shelves are out, wipe the little support ledges and grooves on the inner walls where they rest, as spills often dry there unseen. Rinse your cloth frequently in clean water so you are lifting the grime away rather than smearing it around. Take the chance to wipe the underside of each shelf too, which almost everyone forgets.

Removing and Preventing Odours

Once everything is clean, tackle any remaining smell and set up habits to stop it coming back.

• Keep an open box or small bowl of baking soda on a shelf to absorb odours continuously.
• Store strong-smelling foods like cut onions, garlic paste, and leftovers in airtight containers.
• Cover and date leftovers, and use them within a couple of days rather than letting them sit.
• Wipe up any spill the moment you spot it, before it dries and starts to smell.

Avoid strong perfumed cleaners inside a fridge, since food easily picks up those scents and can taste off. For the outer body, handles, and the top, a wipe with a mild surface disinfectant keeps the most-touched parts hygienic without affecting the food inside. A slice of lemon or a small bowl of coffee grounds left inside for a day can also help absorb a stubborn smell naturally.

If a smell simply will not leave, the source is often the drip tray at the back or the small drain channel that carries condensation away. These hidden spots collect water and food particles and can turn foul over time. Check your appliance manual, and if you can reach the tray safely, empty and wash it as part of your monthly clean.

Keeping Your Fridge Food-Safe

A clean fridge works best when it is also organised sensibly and set to the right temperature.

• Keep the fridge around 4 degrees Celsius and the freezer well below zero for safe storage.
• Do not overpack it, as cold air needs room to circulate around the shelves.
• Store raw meat, chicken, and fish on the lower shelves so they cannot drip onto ready-to-eat food.
• Keep cooked and ready-to-eat items on upper shelves, and vegetables in the crisper drawer.
• Do a quick weekly check for anything nearing its use-by date.

These habits protect your family's health and cut down on food waste, which is money saved too. A well-kept fridge also runs more efficiently, which helps your electricity bill and extends the life of the appliance. Good organisation makes the whole thing easier to keep clean, since you can see everything at a glance.

Avoid a common mistake: do not put hot food straight into the fridge. Let it cool to room temperature first, because a hot vessel raises the internal temperature and forces the compressor to work harder, while the extra steam adds moisture that encourages odour and mould. Keep leftovers in clear, stackable containers so nothing gets lost at the back, and label anything that is easy to forget about.
