How to Get Odour Out of Your Fridge
Fridge odours come from two sources: expired or strongly-scented food, and bacterial and mould growth in spills that have been left too long. Masking the smell with baking soda helps temporarily, but permanently eliminating fridge odours requires a thorough clean and ongoing maintenance.
Step 1 — Remove and Inspect Everything
Remove all food and check expiry dates — expired and rotting food is usually the primary odour source. Remove all drawers and shelves. Smell each drawer and shelf individually to locate the worst areas. Discard any food containers that have absorbed strong odours (old takeout containers, cracked plastic).
Step 2 — Deep Clean the Interior
Wash removable drawers and shelves in hot soapy water and rinse well. For the interior walls and surfaces, wipe down with a solution of 1 tablespoon of baking soda per 1 cup of warm water — baking soda neutralizes acidic and basic odour compounds without leaving a chemical smell of its own. For mould spots (black or pink residue), apply undiluted white vinegar, let sit for 5 minutes, then wipe clean. Dry all surfaces completely before replacing shelves.
Step 3 — Tackle the Drain Hole
Most fridges have a small drain hole at the back of the interior that channels defrost water to the drain pan below. This drain and pan are common sources of odour — bacteria and mould grow in standing water. Clean the drain hole with a pipe cleaner or cotton swab. Remove the drain pan (usually accessible from the front or back bottom of the fridge) and wash with hot soapy water.
Deodorizing After Cleaning
Place an open box of baking soda in the back of the fridge — replace every 3 months. Activated charcoal (available at pet stores or hardware stores) absorbs odours more effectively than baking soda for persistent smells. Coffee grounds in a small bowl work similarly. Avoid scented deodorizers — they add chemical smells to food.
Preventing Future Odours
- Store strongly-scented foods (fish, onions, leftovers) in airtight containers
- Wipe up spills immediately — they become odour sources within days
- Check and clear expired food weekly
- Do a full wipe-down of the interior monthly
