How to Clean Your Washing Machine: A Complete Step-by-Step Guide

The appliance that cleans your clothes needs cleaning too. Over time, detergent residue, fabric softener, minerals from hard water, and trapped moisture create the perfect environment for mold, mildew, and that musty smell that transfers right back onto your laundry. Cleaning your washing machine regularly keeps it running efficiently and your clothes smelling fresh.

Why Your Washing Machine Gets Dirty

Every wash cycle leaves behind a small amount of detergent, dirt, and softener. These deposits build up in places you rarely see: the drum seals, the detergent drawer, and the drain filter. Front-load machines are especially prone to mold because the rubber door gasket traps water after each cycle.

If your laundry comes out smelling less than fresh, or you notice a musty odor when you open the door, it is time for a deep clean.

How Often Should You Clean It?

  • Monthly: Run a cleaning cycle and wipe down the gasket and drawer
  • Weekly: Leave the door open after use to let the drum dry
  • After every wash: Wipe excess water from the door seal on front-loaders

Cleaning a Front-Load Washing Machine

Step 1: Clean the Door Gasket

The rubber seal around the door is the number one spot for mold. Pull it back gently and wipe away trapped hair, lint, and residue with a cloth dipped in a mix of warm water and white vinegar. For stubborn mold, use a paste of baking soda and water.

Step 2: Run a Hot Cleaning Cycle

Add two cups of white vinegar to the detergent dispenser and run the hottest, longest cycle with no clothes inside. The heat and acidity dissolve buildup and kill bacteria.

Step 3: Scrub with Baking Soda

After the vinegar cycle, sprinkle a half cup of baking soda directly into the drum and run a second hot cycle. This neutralizes odors and removes any remaining residue.

Step 4: Clean the Detergent Drawer

Remove the drawer completely and soak it in warm soapy water. Scrub the compartments and the cavity it slides into, where black mold often hides.

Step 5: Check the Drain Filter

Most front-loaders have a filter behind a small panel at the bottom front. Place a towel down, open it, and clear out lint, coins, and debris.

Cleaning a Top-Load Washing Machine

Step 1: Fill and Add Vinegar

Set the machine to the hottest, largest load setting. Once it fills, add four cups of white vinegar, let it agitate for a minute, then pause the cycle for an hour.

Step 2: Add Baking Soda

After the soak, add one cup of baking soda and let it sit for another 30 minutes before completing the cycle.

Step 3: Wipe the Interior

While the machine soaks, use a cloth dipped in the vinegar water to wipe the lid, the top rim of the drum, and the fabric softener and bleach dispensers.

Step 4: Run a Rinse Cycle

Finish with a final hot rinse to flush away loosened grime.

Keeping Your Machine Fresh Between Cleanings

  • Use the right amount of detergent. More is not better and leads to buildup
  • Switch to high-efficiency (HE) detergent if you have an HE machine
  • Leave the door and detergent drawer open between loads
  • Remove wet laundry promptly so the drum can dry
  • Wipe the gasket dry after each front-load cycle

When to Call a Professional

If you have done a deep clean and still notice persistent odors, leaks, or drainage problems, there may be a clog deeper in the drain hose or pump. At that point, a service technician can inspect the internal components.

Final Thoughts

A clean washing machine works better, lasts longer, and protects your laundry from the very grime you are trying to wash away. With white vinegar, baking soda, and a monthly routine, you can keep your machine fresh without harsh chemicals. Set a reminder for the first of each month, and your nose and your clothes will thank you.
