How to Deep Clean a Washing Machine in 2026: Step-by-Step

A washing machine makes everyday life easier, but like any appliance, it needs regular care to stay fresh and work efficiently. Over time, detergent residue, fabric lint, and moisture build up inside your machine. This buildup creates the perfect environment for mould, mildew, and unpleasant smells, something many homeowners notice when clean clothes start coming out with a musty scent.

The good news? With a simple routine and the right method, you can deep clean your washing machine and keep it running at its best. Whether you own a front-load or top-load washer, this guide walks you through every step. And if your schedule is packed, professional cleaning services can make the job even easier, especially if you’re booking home deep cleaning, or appliance care.

Why Cleaning Your Washing Machine Is Important

Even if your washer looks spotless on the outside, the inside can hide layers of soap scum, moisture, bacteria, and odour-causing grime. This buildup affects both your clothes and the machine’s performance.

Here’s why regular cleaning matters:

  • Prevents odours caused by mould and mildew
  • Helps your washer run more efficiently and last longer
  • Keeps clothes fresher and prevents residue stains
  • Reduces the risk of maintenance issues and costly repairs

How Often Should You Clean Your Washing Machine?

How frequently you clean depends on your washer usage, water quality, and laundry habits.

Recommended Cleaning Frequency

Usage Level

Deep Clean Frequency

Quick Maintenance

Heavy use (1+ loads daily)

Once a month

Weekly gasket wipe

Moderate use (3–5 loads weekly)

Every 6–8 weeks

Bi-weekly gasket wipe

Light use (1–2 loads weekly)

Every 3 months

Monthly gasket wipe

If you live in a hard-water area, clean your washer more often. Mineral deposits speed up buildup, much like how homes require frequent deep cleaning in dusty or humid environments.

Step-by-Step: Deep Cleaning a Front-Load Washing Machine

Front-load washers are efficient but notorious for trapping moisture and detergent in their rubber seals. This makes them prone to musty smells without proper maintenance.

Step 1: Empty the Drum and Clean the Gasket

Gently pull back the rubber gasket around the door. This area often hides lint, hair, detergent residue, and even mould.

  • Wipe with a damp microfiber cloth
  • Use a vinegar-and-water mix for stubborn mould
  • Pay attention to creases and folds where grime collects

Regular gasket cleaning reduces odours dramatically.


Step 2: Run a Hot Cycle With Vinegar

  • Pour 2 cups of white vinegar into the detergent dispenser
  • Select the hottest, longest cycle
  • Run the washer empty

Vinegar breaks down buildup, kills bacteria, and helps remove lingering smells.

Step 3: Clean the Detergent Drawer and Seals

While the vinegar cycle runs or cools down:

  • Remove the detergent drawer
  • Soak in warm, soapy water
  • Scrub with a toothbrush
  • Wipe the drawer cavity

This small but often overlooked step prevents mold, much like details handled during commercial cleaning or a full deep cleaning service.

Step 4: Run a Baking Soda Cycle

Sprinkle ½ cup baking soda directly into the drum and run another hot cycle. Baking soda neutralizes odours and helps remove leftover residue in the washing machine

Step 5: Clean the Filter and Let the Machine Dry

Locate the drain filter (usually at the bottom front):

  • Place a tray or towel underneath
  • Twist open the filter cap slowly
  • Remove debris (lint, coins, hair)
  • Rinse and reinstall

Leave the door and drawer open afterward so everything dries completely. This prevents mildew from returning.

Step-by-Step: Deep Cleaning a Top-Load Washing Machine

Top-load washers are easier to maintain, but residue still builds up over time.

Step 1: Fill With Hot Water and Add a Cleaning Solution

Set your washer to the largest load size and hottest water setting. When the drum fills:

  • Add 4 cups vinegar for light cleaning
  • Or 3 cups vinegar + ½ cup baking soda for heavy buildup

The fizzing helps loosen stubborn residue.

Step 2: Soak to Loosen Residue

Let the mixture soak for 1–3 hours. Use the solution to:

  • Wipe the agitator
  • Clean the lid and hinges
  • Wipe exterior surfaces

Soaking ensures a thorough clean similar to professional deep cleaning services.

Step 3: Run a Full Wash Cycle

Resume the cycle to flush loosened grime out of the machine. If residue remains, run another rinse cycle.

Step 4: Scrub the Agitator and Lid

Remove the agitator if possible and scrub with a brush. For non-removable agitators, use a long-handled brush.

Pay attention to narrow areas where grime collects — spots often overlooked without professional cleaning services.

Step 5: Final Rinse and Dry

Run one more hot rinse cycle to remove any vinegar scent. Then:

  • Wipe the drum dry
  • Leave the lid open for ventilation

Good airflow prevents that musty washer smell from coming back.

Alternative Cleaning Methods

If vinegar and baking soda aren’t enough, here are some reliable alternatives.

1. Bleach for Heavy Mold and Odour

Bleach is best for severe mould or strong smells:

  • Add 1 cup chlorine bleach
  • Run the hottest wash cycle
  • Follow with an extra rinse

Important: never mix bleach with vinegar.

2. Washing Machine Cleaning Tablets

Brands like Affresh, Tide, and OxiClean offer convenient cleaning tablets:

  • Drop a tablet into the drum
  • Run a hot cycle

These tabs are perfect for busy families, landlords doing move in and out cleaning, or workplaces scheduling regular commercial cleaning.

3. Natural DIY Cleaners

Eco-friendly options include:

  • Lemon juice + baking soda
  • Tea tree oil for antibacterial cleaning
  • Hydrogen peroxide for gentle whitening and disinfection

These methods are safe for routine upkeep and homeowner-friendly.

Frequently Asked Questions

Can I mix vinegar and bleach?

No. This creates toxic chlorine gas.

Why does my washing machine smell bad?

Odours come from trapped moisture, detergent residue, and mould. Routine deep cleaning and airflow help prevent this.

How do I clean a washer that hasn’t been used in a long time?

Run a hot cycle with vinegar, wipe the drum and seals, and use a bleach cycle if mould is visible.

Conclusion

Keeping your washing machine clean doesn’t have to be complicated. A simple routine prevents odours, extends the machine’s lifespan, and keeps your laundry fresh. Whether you handle it yourself or prefer hiring cleaning services, maintaining your washer is an easy way to protect your home and avoid costly repairs.
