How to get rid of bad smells in your fridge

First things first—clear everything out. Yeah, it’s a pain, but you can’t clean what you can’t see. Pull out all the food, condiments, and those mystery containers lurking in the back. Check expiration dates and toss anything that’s past its prime (looking at you, jar of pickles from 2022). If something’s still good but you know you won’t eat it, consider donating it. Pro tip: Do this right before trash day so you’re not stuck staring at a pile of expired yogurt in your kitchen for a week. While you’re at it, take out any removable shelves, drawers, or bins—these’ll need a good scrub too. Oh, and if you find a science experiment growing in the back, don’t panic. Just toss it and move on. We’ve all been there.

Now that your fridge is empty, it’s time to give it a proper bath. Grab some warm, soapy water—dish soap works great—and a sponge or microfiber cloth. Avoid harsh chemicals like bleach or ammonia; they can leave behind strong smells that’ll mix with your food later. Start with the shelves and drawers you pulled out. Scrub them in the sink (or the bathtub if they’re big), then rinse and dry with a clean towel. For the inside of the fridge, focus on the walls, door seals, and any nooks where crumbs or spills might hide. Don’t forget the top of the fridge—it’s a dust magnet and can contribute to odors. If you’ve got stubborn stains or sticky spots, a paste of baking soda and water can work wonders. Just mix a couple tablespoons of baking soda with a little water, apply it to the stain, let it sit for a few minutes, then scrub and rinse.

Once everything’s clean and dry, it’s time to tackle the lingering smells. Baking soda is your best friend here—it’s cheap, natural, and super effective at absorbing odors. Grab an open box (or a small bowl) and place it on one of the shelves. If you want to get fancy, you can mix baking soda with a few drops of essential oil like lemon or peppermint for a fresh scent. Another trick? Coffee grounds. Yep, just like they absorb odors in your freezer, they’ll work in your fridge too. Fill a small bowl with fresh grounds and leave it in there for a day or two. Activated charcoal is another powerhouse for odor removal—you can find it in pet stores or online. Just pop a few pieces in a breathable bag (like a muslin sack) and leave it in the fridge. Swap out the baking soda, coffee, or charcoal every month or so to keep smells at bay.

Sometimes, the source of the smell isn’t obvious. Take a few minutes to inspect the less obvious spots where odors can hide. Start with the drain hole at the back of the fridge—it can get clogged with gunk and start smelling funky. Use a pipe cleaner or a cotton swab dipped in vinegar to clean it out. Next, check the door seals (those rubber gaskets around the edge). If they’re dirty or damaged, they can trap odors and even let warm air in, making your fridge work harder. Wipe them down with soapy water, then dry thoroughly. If they’re cracked or peeling, you might need to replace them—most hardware stores carry replacements for popular fridge models. Finally, peek under the fridge. Spills or crumbs can accumulate down there, especially if you’ve got a bottom-freezer model. Slide the fridge out (carefully!) and sweep or vacuum the area. If it’s really grimy, wipe it down with a damp cloth.

Now that your fridge is sparkling and smell-free, let’s keep it that way. First, store food properly to prevent odors from spreading. Use airtight containers for leftovers, and wrap strong-smelling foods like onions or fish in plastic wrap or foil before popping them in. Keep a box of baking soda in the fridge at all times—it’s a small investment that makes a big difference. Make it a habit to do a quick fridge check once a week. Toss anything that’s past its prime, wipe up spills as soon as they happen, and give the shelves a quick wipe-down with a damp cloth. If you’re storing produce, use those crisper drawers—they’re designed to keep fruits and veggies fresh longer. And here’s a pro tip: line your shelves with plastic wrap or wax paper. It’s easier to replace than scrubbing off dried-on spills later. Finally, don’t overpack your fridge. Air needs to circulate to keep everything at the right temperature and prevent odors from building up.

If you’ve done all the cleaning and deodorizing but still notice a faint smell, it’s time to bring in the big guns. A DIY air purifier can work wonders. Grab a small bowl and fill it with white vinegar—it’s a natural odor neutralizer. Leave it in the fridge overnight, then remove it in the morning. The vinegar smell will dissipate quickly, taking other odors with it. Another option? A slice of lemon or orange. Citrus is great at freshening up the air, and it’ll leave a light, pleasant scent behind. Just cut a lemon in half, place it on a small plate, and let it work its magic for a day or two. If you’re dealing with a particularly stubborn smell, try simmering a pot of water with citrus peels, cinnamon sticks, and a splash of vinegar on the stove. The steam will help neutralize odors in the air, and your whole kitchen will smell amazing. Just don’t leave the pot unattended!

Sometimes, all your fridge needs is a little reset to kick those odors to the curb. Start by unplugging it for a few hours—this gives it a chance to defrost and air out. While it’s unplugged, leave the door open to let fresh air circulate. If you’ve got a freezer, this is a great time to defrost it too. Once it’s unplugged, wipe down the interior one more time with a mix of equal parts water and vinegar. This’ll help neutralize any lingering smells. When you plug it back in, set the temperature to 37°F (3°C) for the fridge and 0°F (-18°C) for the freezer. These temps keep food fresh without overworking your fridge. If your fridge has a built-in air filter (some newer models do), now’s the time to replace it. Check your manual for instructions—it’s usually a quick swap. Finally, give your fridge a day or two to stabilize before restocking it. This’ll help ensure everything stays fresh and odor-free.
