Let me guess—you toss your dirty clothes in the washing machine, press start, and assume it’s cleaning both your laundry and itself. If only it were that easy.

Here’s the truth: washing machines need a regular cleaning routine too. Otherwise, you’re left with funky odors, soap scum buildup, mildew in the seals, and ultimately—less-than-fresh clothes. I’ve worked with dozens of homeowners and facility managers who’ve learned this the hard way.

So today, I’m walking you through the step-by-step routine to clean and maintain your washing machine like a pro. Whether you own a top loader, front loader, or high-efficiency model, these tips will help you prevent mold, boost efficiency, and extend your machine’s life.

Step 1: Clean the Drum (Monthly)

Why: Detergent residue, minerals from hard water, and body oils accumulate over time, creating the perfect breeding ground for mildew and odor.

How to do it:

  1. Run an empty hot cycle with 2 cups of white vinegar.
  2. Add ½ cup of baking soda directly into the drum.
  3. Let the cycle finish. Wipe the drum with a microfiber cloth after.

Pro tip: For store-bought options, try Affresh Washing Machine Cleaner or Tide Washing Machine Cleaner (both highly rated on Amazon).

Step 2: Wipe Down the Gasket and Door (Every 1-2 Weeks)

Especially important for front loaders, where mold often hides in the rubber gasket.

Steps:

  • Mix a solution of 1:1 water and vinegar or use an antibacterial wipe.
  • Pull back the rubber seal and clean all around, including hidden folds.
  • Wipe down the interior door glass.

Why it matters: That black gunk you sometimes see? It’s mold, and it smells. Cleaning it prevents buildup and prolongs the seal’s lifespan.

Step 3: Clean the Detergent Drawer (Monthly)

What to do:

  • Remove the drawer completely (check your manual).
  • Soak it in warm, soapy water.
  • Use an old toothbrush to scrub away buildup.
  • Dry thoroughly and replace.

This prevents clogging and ensures your detergent is dispensing properly—essential for machines using liquid HE detergent or fabric softeners.

Step 4: Clean the Filter (Every 2-3 Months)

Why: Lint, coins, hair, and other debris get trapped and can block drainage.

Steps:

  • Unplug the machine.
  • Locate the filter (usually near the base, behind a panel).
  • Remove and clean under running water.
  • Use a towel to catch excess water.

Machines like the Samsung Smart Front Loaders or LG ThinQ Washers have accessible filters you can clean yourself. Older models may need a technician.

Step 5: Leave the Door Open After Every Load

This one’s simple, free, and effective.

Why? It allows air circulation, preventing moisture buildup and mildew growth.

For front-loaders, also consider a door prop or washer door latch clip to keep it slightly ajar without swinging open.

Step 6: Use the Right Detergent

Too much detergent = more residue = gunk in your machine.

Tips:

  • Use HE (high-efficiency) detergent for HE machines.
  • Follow the measuring lines on the cap—more soap doesn’t mean cleaner clothes.
  • If you have hard water, consider adding a water softener or using detergents like Arm & Hammer Plus OxiClean.

Step 7: Descale if You Have Hard Water (Every 3-6 Months)

Minerals from hard water can build up inside your drum and pipes.

Use a descaling solution like Eco-Gals Eco Swirlz or DIY with a mix of citric acid and baking soda.

Step 8: Deep Clean the Exterior (Monthly)

  • Wipe down control panels with a damp microfiber cloth.
  • Vacuum behind the washer to remove dust.
  • Check hoses for wear or leaks—replace every 5 years.

Step 9: Maintain the Hoses (Annually)

Inspect for:

  • Cracks
  • Bulges
  • Loose fittings

For peace of mind, switch to stainless steel braided hoses, which are far more durable than rubber ones.

Step 10: Add These Cleaning Products to Your Toolkit

  • Affresh Washing Machine Tablets (monthly drum clean)
  • OxiClean Washing Machine Cleaner
  • Citric acid powder (natural descaling)
  • Microfiber cleaning cloths
  • Washer door prop clip

Think of your washing machine like a gym buddy. It puts in the work, but it needs some TLC to perform at its best. By giving it a little monthly love—with deep cleans, smart detergent use, and regular maintenance—you’ll extend its lifespan and keep your laundry truly fresh.

And let’s be honest: pulling a clean-smelling towel out of the wash is one of life’s little pleasures.
