Knowing how to clean the refrigerator properly is essential for food safety, appliance efficiency, and a fresh-smelling kitchen. Even though refrigerators are kept at a cool 40°F (4°C) or below, bacteria and mold can still grow, especially in hidden drips, expired foods, or poorly sealed containers. If left unchecked, contamination can spread and ruin otherwise safe food. With regular cleaning, you’ll extend the life of your food and keep your fridge working efficiently.
Why Refrigerator Cleaning Matters
Refrigerators harbor hidden trouble spots, under drawers, in door gaskets, behind shelving hardware, where moisture, crumbs, and spills collect. Mold and bacteria thrive in these areas. Regular deep cleaning not only removes grime but also helps eliminate odors and keep the environment safe for food storage.
DIY Refrigerator Cleaning Solution
Use this simple and effective formula:
1/4 cup baking soda
1 quart warm water
Baking soda is a mild, food-safe cleaner that helps sanitize, brighten, and deodorize. You typically don’t need to rinse unless you’ve used a large amount and see a visible residue.
Step 1: Unload the Refrigerator
Before you can get into how to clean the refrigerator, you’ll need to empty it:
Pull up a wastebasket, box, or cooler.
Check expiration dates and toss anything that’s gone bad or you know you won’t use (looking at you, 15-year-old jar of tamarind paste).
Group items to keep by category: dairy, condiments, leftovers, etc.
Store perishable or frozen foods temporarily in a cooler or second fridge to prevent spoilage.
Work quickly, refrigerated foods shouldn’t sit out for more than 2 hours.
Step 2: Remove and Soak Shelves and Drawers
Take out all removable parts, shelves, bins, and drawers.
Place them in a clean sink or bathtub.
Spray with a household cleaner or baking soda solution and let them soak for easier scrubbing.
Use a soft brush or sponge to clean; rinse thoroughly and dry with a clean towel.
Avoid using hot water immediately on cold glass shelves, let them come to room temperature first to prevent cracking.
Step 3: Wipe Down the Interior
Using a clean cloth and the baking soda solution, wipe down:
Inside walls
Shelving brackets
Door interiors and gaskets
The ceiling and floor of the refrigerator
Use a toothbrush to clean corners, crevices, and rubber seals.
If needed, switch to a mild dish soap and water solution, but make sure to rinse and dry thoroughly to avoid soap residue.
Step 4: Reassemble and Reload
Dry all removable parts and place them back in the fridge.
Before returning items, wipe jars, bottles, and containers to prevent sticky messes.
Rinse and dry fresh produce before putting it back into the drawers.
Consider lining drawers with paper towels or washable liners to catch future spills.
How to Keep Refrigerator Odors Away
After you’ve mastered how to clean the refrigerator, stay ahead of future odors with a few smart habits:
Keep an open box of baking soda in the fridge to absorb odors, replace every 30–60 days.
Store leftovers in airtight containers.
Wipe up spills immediately, this is the #1 cause of bad smells.
Routinely check for expired or spoiled food and discard promptly.
Before weekly grocery trips, reorganize and toss anything old so you can put new perishables away quickly.
Empty and clean ice cube trays regularly, ice can absorb fridge odors over time.
Keeping a Fresher Fridge
Clean condenser coils (usually behind or underneath the fridge) every 6 months to keep your appliance running efficiently.
If your fridge has a water dispenser or ice maker, refer to the manufacturer’s guide on how to clean and sanitize these parts.
Don’t forget the freezer! Clean it on the same schedule if it’s part of your refrigerator unit.
