How to Clean a Washing Machine: Complete Step-by-Step Guide & Maintenance Tips (2025)

Funny story – last year I ignored my washing machine for months until my towels started smelling like wet dog. Turns out, that "clean" smell doesn't just happen by magic. Whether you've got a front-loader or top-loader, learning how to clean laundry machine properly is non-negotiable unless you enjoy musty gym socks.

Why Bother Cleaning Your Washing Machine?

Three words: mold, bacteria, and stink. That damp environment? Perfect breeding ground. I tested mine once – swabbed the rubber seal and sent it to a lab buddy. Results came back with more germs than a subway handrail. And get this: Consumer Reports found 60% of front-loaders develop mold if not maintained.

What Happens When You Don't Clean

  • Black mold in rubber gaskets (I scraped out enough to fill a shot glass once)
  • Musty odor that transfers to clothes
  • Reduced washing efficiency – detergent buildup blocks water flow
  • Mechanical failures from limescale ($200 repair bill taught me this)

What You'll Need to Clean Your Washing Machine

Item Why You Need It Cost Estimate
White vinegar Dissolves mineral deposits | Kills bacteria $3/gallon
Baking soda Scrubs away residue | Neutralizes odors $1/box
Microfiber cloths Lint-free cleaning (old t-shirts work too) $5/pack
Toothbrush (dedicated) Gets into crevices and detergent dispensers $1
Commercial washer cleaner (optional) For heavy buildup – Affresh tablets work well $10/6 tablets

Step-by-Step Guide to Cleaning Your Laundry Machine

Let's get hands-on. I'll walk you through exactly what I do monthly in my LG front-loader:

Cleaning the Interior Drum

This is where the magic happens. Skip this and you're washing clothes in dirty water.

  • Run hot water cycle on highest setting without clothes
  • Pause mid-cycle after drum fills (wait 1 hour)
  • Add 4 cups white vinegar – restart cycle
  • After completion, sprinkle 1 cup baking soda inside
  • Run second hot water cycle

Sounds excessive? Trust me, when I cut corners, I get gray sludge in the filter.

Scrubbing the Rubber Gasket (Front-Loaders)

The mold magnet. Pull back the rubber seal completely – you'll probably find gunk.

  • Wipe with vinegar-soaked cloth
  • Scrub grooves with toothbrush
  • Dry thoroughly with towel (leave door open after every wash!)

Pro tip: Shine flashlight into the folds. Found a Lego in mine last month.

Detergent Dispenser Deep Clean

That slimy feeling? Yeast and detergent scum.

Component Cleaning Method Frequency
Detergent drawer Remove and soak in vinegar water Monthly
Fabric softener compartment Q-tips + baking soda paste Every 2 weeks
Dispenser housing Wipe with diluted bleach (1:10 ratio) Monthly

Cleaning the Drain Pump Filter

Most neglected part. Located behind bottom access panel.

  • Place towels on floor (water WILL spill)
  • Turn filter counterclockwise slowly
  • Remove debris (coins, hair, glitter – always glitter)
  • Rinse under faucet
  • Reinstall securely

My record? 37 cents and a Barbie shoe.

Top-Loader Specific Tip

Agitator removal is crucial. Unscrew the cap, lift straight up. Soak in bathtub with 2 cups vinegar overnight. Scrub with brush. That funk inside will shock you.

Maintenance Schedule That Actually Works

Based on appliance repair tech recommendations (and my trial/error):

Task Frequency Time Required
Wipe door/gasket After every wash 30 seconds
Leave door ajar After every wash 0 seconds (just do it)
Clean detergent tray Weekly 3 minutes
Vinegar wash cycle Monthly 2 hours (mostly unattended)
Filter check Quarterly 15 minutes

Top 3 Cleaning Mistakes (I've Made Them All)

  • Using bleach instead of vinegar – reacts with residues creating toxic chloroform gas (yes, really)
  • Ignoring hard water – if your kettle has limescale, use citric acid monthly
  • Overloading detergent – causes more buildup than dirt (use 1/2 manufacturer's recommendation)

FAQs: Real Questions from My Readers

Why does my washing machine still smell after cleaning?

Check two things: 1) The drain hose loop – should be higher than water level to prevent backflow. 2) Hidden lint in the pump filter housing. Took me 3 cleans to find that one.

Can I use washing machine cleaner tablets monthly?

Yes, but rotate with vinegar. Tablets contain surfactants that build up over time. I do tablets every 3rd month.

How to clean laundry machine with bleach safely?

Only if you've never used vinegar in recent cycles. Run empty hot cycle with 1 cup bleach only in drum. Ventilate the room. Never mix with other cleaners.

Why is there standing water in my drum?

Clogged filter (90% chance) or kinked drain hose. Unplug before investigating. Found a toddler sock blocking mine.

How often to clean front load washer?

Monthly deep clean if you wash daily. Every 2 months for average use. Postponed mine 5 months once – took 3 cycles to fix the mildew smell.

When Cleaning Isn't Enough

If you still get mold after proper maintenance, two possibilities:

  • Faulty door seal – tears trap moisture. Replacement costs $30-$80
  • Drain pump issues – standing water breeds bacteria. Requires professional diagnosis

My neighbor replaced his seal after my advice – said it was like getting a new machine.

Proven Methods That Actually Work

After testing every hack on the internet:

Method Effectiveness Risk Level
Vinegar + baking soda cycles ★★★★★ Safe
Affresh tablets ★★★★☆ Low
Bleach wash ★★★☆☆ Moderate (fumes)
DIY citric acid soak ★★★☆☆ Low
"Self-clean" cycles ★★☆☆☆ Safe but incomplete

Final Reality Check

No magic solution exists. I spent $40 on "miracle" cleaners before accepting that elbow grease wins. Set calendar reminders for monthly maintenance – future you will thank present you. Seriously, it's easier than removing mildew smell from your favorite shirt.
