Your washing machine should leave your clothes fresh and clean—but if you’ve noticed a musty or sour odor coming from it, you’re not alone. Over time, washing machine smells can develop due to moisture buildup, detergent residue, and bacteria or mold growth.
The good news? With a little maintenance and a few simple steps, you can get rid of the smell and keep your machine running in top shape. This guide will walk you through how to get rid of washing machine smell, prevent future issues, and keep your washer smelling fresh every time.
Why does your washing machine smell?
Several factors contribute to a smelly washer, including:
🦠 Bacteria and Mold Growth
Warm, damp conditions inside the drum and rubber seals create the perfect environment for bacteria and mold.
🧼 Detergent and Fabric Softener Residue
Using too much detergent can leave behind a sticky film that traps dirt and odors.
🚫 Clogged Drain or Filter
Lint, dirt, and soap scum can clog the filter and drainage system, causing stagnant water and bad smells.
💧 Standing Water in Seals and Hoses
Water trapped in the rubber gasket or hose can harbor mold and mildew.
❄️ Low-Temperature Wash Cycles
Frequent cold washes don’t kill bacteria effectively, allowing them to thrive.
Signs that your washing machine needs cleaning
Look out for these common indicators:
✔️ Unpleasant Odor – A sour, musty smell that lingers even after a wash.
✔️ Residue on Clothes – Clothes smell damp or stale post-wash.
✔️ Visible Mold or Mildew – Black spots or buildup inside the gasket or drum.
✔️ Slow Draining – Water pooling in the drum after a cycle.
These signs mean it’s time for a deep clean to remove mildew smell from washer components.

✔️ Wipe Down Gasket and Drum Regularly – Dry and clean the drum and rubber seal after use.
