How to Get Rid of Bad Smells in Your Home

Air fresheners and candles mask smells — they don't eliminate them. The only way to permanently remove bad odours is to remove the source. Here's how to find and fix the most common household smell problems.

Identifying the Source

Before any treatment, find where the smell is strongest. Walk room to room, get close to: drains, the space behind the fridge, under the sink, in closets, and near HVAC vents. Smells are almost always source-based, not ambient.

Kitchen Smells

Fridge odour: Clean inside completely including door seals and drip pan. Place open baking soda or activated charcoal inside. Replace every 3 months.

Drain smell: Pour boiling water down the drain, followed by ½ cup baking soda, then 1 cup white vinegar. Let fizz for 15 minutes, flush with hot water. For persistent smell, the issue may be a dry P-trap or biofilm buildup requiring a drain snake.

Garbage/bin smell: Wash bins with dish soap and hot water. Sprinkle baking soda in the bottom under a new bag.

Bathroom Smells

Mildew smell: Source is usually grout, caulking, or the exhaust fan duct. Clean grout with bleach solution, replace mouldy caulking, clean the fan cover and duct.

Drain smell: Same method as kitchen drain. Bathroom drains accumulate hair and soap — a drain snake + boiling water usually resolves it.

Pet Odours

Pet urine contains uric acid crystals that regular cleaning doesn't break down — which is why the smell keeps coming back after you clean. Use an enzyme-based cleaner specifically formulated for pet urine. It breaks down the uric acid permanently.

For carpet: apply enzyme cleaner generously, let sit 15–20 minutes, blot with a clean cloth, sprinkle baking soda, let dry, vacuum.

Musty/Damp Smells

In BC's coastal climate, musty smells are usually mould or mildew. Check: window corners, bathroom ceiling, under-sink cabinets, closets on exterior walls, and any area with poor ventilation. Clean visible mould, improve ventilation, and consider a dehumidifier in damp rooms.

After a Move-Out

Vacant units develop smell quickly from residual cooking grease, drain biofilm, and closed ventilation. A professional move-out clean addresses all of these. Book at maidless.ca.
