How to Clean Out Your Refrigerator Step by Step

Start with a plan and a clear shelf

The fastest way to clean your refrigerator is to empty one shelf at a time, wipe it down, and put back only what you're keeping. Don't try to clean around the food—you'll waste time moving things twice and miss spills hiding underneath. Set a timer for 30 minutes; most people finish a full fridge in that window once they know the order.

Before you begin, decide where your cleaned items will go. Use your kitchen counter, a clean cooler, or even a clean sink as a staging area. This keeps cold food from sitting at room temperature for more than two hours while you work. If you're cleaning on a warm day, use a cooler with ice packs to keep perishables safe.

Gather your supplies first: a trash bag for expired food, a damp cloth or sponge, a small bowl of warm water with a few drops of dish soap, and paper towels or a clean kitchen towel. If your fridge has a strong smell, keep baking soda nearby—you'll use it after cleaning to absorb odors.

Key Takeaways

• Empty one shelf completely, check dates on every item, and wipe the shelf before returning food so spills don't hide under containers.
• Throw out anything past its date, anything with visible mold or off smells, and condiments that have separated or changed color.
• Wipe down the inside walls, door seals, and the rubber gasket where mold and bacteria hide, using warm soapy water and a cloth.
• Place an open box of baking soda on a back shelf to absorb odors, and replace it every three months for best results.
• Organize as you return food: keep raw meat on the lowest shelf, produce in the crisper drawer, and dairy and leftovers at eye level.

Check dates and throw out what's expired

As you remove each item from a shelf, look at the date. Throw out anything past the expiration date, use-by date, or best-by date printed on the package. Don't guess—if you can't read the date or it's faded, assume the food is old and discard it. Expired food takes up space and can harbor bacteria that spreads to other foods.

Beyond dates, use your senses. If something smells sour, musty, or off in any way, throw it out. If you see mold on cheese, yogurt, or jam, discard the whole container—mold roots run deeper than you can see. If a container of leftovers has been in the fridge longer than four days, it's safer to throw it away than to guess whether it's still good.

Check condiments too. Ketchup, mustard, and mayo last a long time, but if the color has changed, it's separated, or it smells vinegary beyond the normal tang, replace it. Old condiments won't make you sick immediately, but they lose flavor and can develop off-tastes that ruin food you add them to.

Wipe shelves, walls, and the door seal

Once a shelf is empty, wipe it with your damp cloth. Pay attention to the corners and edges where spills pool and dry. If something is stuck on, let the warm soapy water sit for a minute to soften it, then wipe again. Dry the shelf with a paper towel or clean cloth so water doesn't drip onto the shelf below.

Don't skip the walls and the back of the fridge. Spills splash higher than you think, and dried food particles collect dust and bacteria. Wipe the side walls and the back panel with the same warm soapy cloth. If your fridge has a glass shelf, wipe both sides so you can see what's stored below.

The rubber door seal—the gasket that runs around the edge of the door—is where mold and mildew hide. Wipe it carefully with your damp cloth, working into the folds. If you see black or pink spots, that's mold or bacteria; wipe it away and dry it completely. A dry gasket stays cleaner longer than a wet one.

Return food in the right order

As you put food back, follow this order from bottom to top: raw meat and poultry on the lowest shelf (so drips don't land on other food), then dairy and eggs, then prepared foods and leftovers, then produce in the crisper drawer, and finally condiments and drinks on the door. This layout keeps bacteria from spreading downward.

Don't crowd the shelves. Air needs to circulate around food so cold reaches everything evenly. If you can't see what's on a shelf because it's packed too full, you'll forget what you have and food will expire before you use it. Leave at least an inch of space between items.

Put items you use often at eye level so you see them and use them before they expire. Store leftovers in clear containers so you can see what's inside and when you put it in. Label containers with the date using a piece of tape and a marker—it takes 10 seconds and prevents guessing later.

Deal with odors using baking soda

If your fridge smells stale or sour even after cleaning, place an open box of baking soda on a back shelf, away from food. Baking soda absorbs odors by trapping them in its porous surface. It works best in a small, enclosed space like a refrigerator because the air circulates slowly and the baking soda has time to work.

Replace the baking soda every three months, or sooner if the smell returns. You can test whether it's still working by opening the box and smelling it—if it smells like the fridge (sour or stale), it's saturated and needs replacing. A box that still smells like baking soda has more capacity to absorb odors.

If the smell is very strong, it usually means something is rotting inside. Check the back corners, under the vegetable drawers, and around the door seal. Spills that dry in hard-to-reach places can smell terrible. Once you find and clean the source, the baking soda will finish the job.

Clean the drawers and remove buildup

Pull out the vegetable crisper drawer and any other removable drawers. Wash them in warm soapy water in your sink, dry them completely, and put them back. While the drawers are out, wipe the shelf underneath with your damp cloth—moisture and vegetable scraps collect there and can cause mold.

If a drawer has a buildup of dried food or slime, soak it in warm soapy water for five minutes before scrubbing. Use a soft brush or cloth to avoid scratching plastic. Dry it thoroughly before returning it to the fridge, because moisture left inside will grow mold.

Check the drain hole at the bottom of the fridge if your model has one. It's usually a small opening in the back corner of the floor. If it's clogged with food particles or ice, water pools and smells bad. Use a small stick or pipe cleaner to clear it gently, then flush it with a little warm water.

Set a cleaning schedule so it stays manageable

A full deep clean every month keeps your fridge fresh and prevents the buildup that makes cleaning harder. Mark it on your calendar—the first Saturday of each month, or the day after you grocery shop. When cleaning is routine, it takes less time and you catch expired food before it spoils other items.

Between deep cleans, wipe up spills the day they happen. If you see something dripping or leaking, clean it immediately so it doesn't dry and stick. A quick wipe takes 30 seconds and saves you scrubbing later. Keep a cloth or paper towels in a drawer near the fridge so you're not tempted to skip it.

Every time you put groceries away, move older items to the front so you use them first. This simple habit—called "first in, first out"—means less food expires and your fridge stays organized without extra work.

Frequently Asked Questions

Can I use bleach or other cleaners inside my refrigerator?

No. Bleach and harsh chemical cleaners leave residue that can transfer to food and make you sick. Warm soapy water is safe, effective, and won't damage plastic or rubber seals. If you want extra disinfection, a cloth dampened with white vinegar works well—the smell fades as it dries, and vinegar is food-safe.

What should I do if my fridge smells bad but I can't find the source?

Check the drain hole at the bottom back of the fridge—a clogged drain traps water and food particles that smell terrible. Also check under the vegetable drawers and behind the door seal. If the smell is very old, it may be in the insulation itself; in that case, baking soda and time will help, but the smell may linger for weeks.

How long can I leave food out while I'm cleaning?

Keep perishable food out of the fridge for no more than two hours. If your kitchen is warm (above 90°F), reduce that to one hour. Use a cooler with ice packs if you're cleaning on a hot day or if your cleaning will take longer than 30 minutes.

Should I unplug my refrigerator to clean it?

You don't need to unplug it for a routine wipe-down. If you're cleaning the coils on the back or underneath (which you should do once a year), unplug it first. For regular shelf and wall cleaning, leaving it plugged in keeps food cold while you work.

What's the best way to organize food after cleaning?

Store raw meat on the lowest shelf so drips don't land on other food, dairy and eggs on the next shelf up, prepared foods and leftovers in the middle, produce in the crisper drawer, and condiments on the door. Keep frequently used items at eye level so you remember to use them before they expire.
