How to Clean Your Washing Machine the Right Way (and Why It Matters for Your Laundry)

When was the last time you cleaned your washing machine?

If you’re drawing a blank, you’re not alone. Most of us assume the washer cleans itself — after all, it’s constantly running soap and water through its system, right? But here’s the thing: your washing machine is actually one of the dirtiest spots in your home. Every load leaves behind traces of detergent, dirt, body oils, and fabric fibers. Over time, that buildup creates a breeding ground for bacteria, mold, and mildew. The result? Clothes that smell weird even after washing, a funky odor wafting from the drum, and a machine that’s working way harder than it should.

The good news is that cleaning your washing machine is easier than you think — and the payoff is huge. We’re talking fresher-smelling laundry, a longer-lasting appliance, and cleaner clothes that actually feel clean. Let’s walk through how to do it right.

Why You Should Clean Your Washing Machine

Your washing machine is supposed to make things clean, so it feels counterintuitive that it needs cleaning too. But think about what goes into every load: sweat, dirt, pet hair, food stains, and whatever else life throws at your clothes. Add in liquid detergent (which can be thick and sticky) and fabric softener (which leaves a waxy coating), and you’ve got a recipe for serious buildup.

Detergent and Grime Create a Hidden Mess

Most detergents don’t rinse away completely — especially if you’re using too much or washing in cold water. That leftover soap clings to the drum, hoses, and rubber gasket. It mixes with lint, dirt, and minerals from hard water, creating a slimy film you can’t always see but can definitely smell. Over time, this gunk hardens and traps moisture, which is exactly what bacteria and mold need to thrive.

Your Clothes Are Picking Up What’s Left Behind

If your washer is dirty, your clothes are coming out dirty too — even if they look clean. That musty smell? That’s bacteria transferring from the drum onto your towels and shirts. The grayish tint on your white laundry? That’s detergent residue and minerals coating the fabric. Basically, you’re washing your clothes in a machine that’s recycling its own mess.

Front-Loaders vs. Top-Loaders: Both Need Attention

Front-loading washers are notorious for smelling bad because they use less water and have that rubber door gasket where moisture loves to hide. But top-loaders aren’t off the hook either. They might not trap water the same way, but they still accumulate detergent scum, especially around the agitator and under the rim of the drum. Both types need regular cleaning — front-loaders just need it a little more often.

If you’ve ever opened your washer and been hit with a damp, sour smell, you know exactly what we’re talking about. That smell doesn’t just stay in the machine. It clings to your clothes, your towels, and anything else you wash. And no amount of extra detergent or fabric softener is going to cover it up.

How Often Should You Clean Your Washing Machine?

Ideally, you should deep clean your washing machine once a month. Think of it like brushing your teeth — if you skip it for too long, things get gnarly fast.

That said, some households need to clean more often:

• Large families doing multiple loads daily? Clean every 2–3 weeks.
• Pet owners washing blankets and bedding regularly? Same deal.
• Live in a humid climate? Moisture sticks around longer, so bump up your cleaning schedule.
• Using liquid detergent or fabric softener? These leave more residue than pods or sheets, so monthly cleaning is non-negotiable.

If you’re only doing a few loads a week and using low-residue detergent (like detergent sheets), you can probably stretch it to every 6 weeks. But don’t push it past that. A clean washer = cleaner clothes, and that’s worth the 30 minutes it takes.

Step-by-Step: The Right Way to Clean Your Washing Machine

Cleaning your washer isn’t complicated, but doing it the right way makes all the difference. Here’s the full rundown.

Step 1: Run a Hot, Empty Cycle

Start by running your washing machine on the hottest, longest cycle — completely empty. No clothes, no towels, nothing. Hot water helps dissolve built-up detergent and kills bacteria that cold water can’t touch. If your machine has a “clean” or “tub clean” setting, use that. If not, just select the hottest water and longest cycle available.

This is your baseline clean. It loosens grime and preps the drum for a deeper treatment.

Step 2: Add a Washing Machine Cleaner Tablet

Here’s where you level up. Drop a washing machine cleaner tablet into the drum before starting another hot cycle. These tablets are specifically designed to break down detergent residue, eliminate odors, and sanitize the drum without harsh chemicals.

CLEARALIF’s Washing Machine Cleaner Tablets are a great eco-friendly option — they’re plastic-free, dissolve completely, and use plant-based ingredients to cut through buildup naturally. Just toss one in, run the cycle, and let it do the work. No scrubbing required.

If you don’t have cleaner tablets on hand, you can use two cups of white vinegar or a half-cup of baking soda as a natural alternative. Pour the vinegar into the detergent drawer (or directly into the drum for top-loaders) and run a hot cycle. Vinegar is acidic enough to break down soap scum and kill mildew, though it won’t be quite as powerful as a dedicated cleaner.

Pro tip: Never mix vinegar and baking soda in the same cycle — they neutralize each other and you end up with fizzy water that doesn’t actually clean anything.

Step 3: Wipe Down the Rubber Gasket, Door, and Detergent Drawer

After your cleaning cycle finishes, grab a microfiber cloth and some warm soapy water (or a vinegar-water solution). This is when you tackle the spots the cycle can’t reach:

• The rubber gasket (on front-loaders): Pull it back gently and wipe out any gunk, hair, or mildew hiding in the folds. This is where most of the gross stuff lives.
• The door or lid: Wipe down the inside and outside, especially around the edges.
• The detergent drawer: Pull it out completely and rinse it under warm water. Use an old toothbrush to scrub out any dried detergent or fabric softener buildup in the compartments.

These areas don’t get cleaned during the cycle, so they need your attention. It only takes a few minutes, but it makes a huge difference in keeping your machine fresh.

Step 4: Leave the Door or Lid Open

After you’re done, leave the washer door or lid open for a few hours (or overnight) to let the drum air out completely. Moisture is mildew’s best friend, and a closed drum stays damp way longer than you’d think. Prop the door open and let fresh air circulate — it’s the easiest way to prevent that sour smell from creeping back.

If you have a front-loader, make this a habit after every wash. Just leave the door cracked so air can flow through. It’s a tiny step that saves you from bigger headaches down the road.

Bonus Tips: Keep Your Washer Fresh Longer

Once your machine is sparkling clean, here’s how to keep it that way between deep cleans:

• Don’t overload your washer. Cramming too many clothes in means detergent and water can’t circulate properly, which leads to buildup. Aim to fill the drum about three-quarters full.
  
• Use the right amount of detergent. More soap doesn’t mean cleaner clothes — it just means more residue. If you’re using liquid detergent, cut your usual amount in half and see if your clothes still come out clean (they probably will). Better yet, switch to pre-measured laundry sheets that dissolve completely and rinse away without leaving gunk behind.
• Remove clothes immediately after washing. Leaving wet laundry in the drum — even for a couple of hours — creates the perfect environment for mildew. Set a timer on your phone if you need to. Your future self (and your nose) will thank you.
• Wipe down the drum after each use. It sounds extra, but a quick swipe with a towel after you empty the washer keeps moisture from settling in. It takes 10 seconds and prevents so many problems.
• Run a “rinse and spin” cycle occasionally. If you do a lot of cold-water washing, run an extra rinse cycle once a week to flush out any lingering detergent or fabric softener.

These small habits add up. You’ll notice your clothes smell fresher, your washer stays cleaner longer, and you won’t have to deep clean quite as often.

Your Washer Deserves Some TLC Too

It’s easy to forget that the appliance doing all the dirty work needs a little care of its own. But when you think about it, your washing machine handles some of the grossest stuff in your home — sweat-soaked gym clothes, muddy jeans, pet blankets, baby blowouts. It’s only fair to give it a reset every now and then.

A clean washing machine means cleaner clothes, fewer odors, and a machine that lasts longer. It’s one of those home care tasks that feels like a chore until you see (and smell) the difference. Then it just feels like common sense.
