How Often to Run Washing Machine Cleaner

Why You Should Care About Cleaning Your Washing Machine

Let’s be real—your washing machine is the unsung hero of your household. It hauls the stank, the mud, the mystery stains, and yet, you rarely think about its internal dirtiness. But here’s a hot tip: your washing machine is bound to get grimy over time, harboring detergent buildup, mold, mildew, and funky odors that can turn your freshly laundered clothes into noses crinklers.

Cleaning it regularly isn’t just about keeping smells in check; it boosts performance, protects your investment, prevents repair headaches, and extends the machine’s life. Sounds like a win-win, right? Now, cue dramatic pause… how often should you actually run that washing machine cleaner?

The Golden Rule: Once a Month or Every 30 Loads

Experts from Avocado Green Mattress and Affresh agree: the sweet spot for cleaning your machine with a washing machine cleaner is monthly or roughly every 30 wash cycles. This cadence keeps the grime, residues, and microbes from setting up shop.

Why monthly? Because on average, most households do multiple loads weekly—two to three loads a week quickly add up, and that’s when detergents and softeners, along with dirt, start leaving their “footprints” inside.

So mark your calendar or set a reminder: one wash cycle with a washing machine cleaner once a month, no excuses.

Front Loader vs. Top Loader: The Cleaning Frequency Showdown

Not all washing machines are created equal, and the way they get dirty varies too. According to Professional Appliance, here’s what you need to know:

  • Top-loading machines: These work more like your classic agitator, with ample ventilation so mold has fewer chances to lurk. Cleaning once a month with a washing machine cleaner is recommended to keep them running smoothly and smelling fresh.
  • Front-loading machines: These beauties are efficient but tend to be airtight, trapping moisture inside. This creates the perfect storm for mildew and funky odors. For these, quarterly cleaning—every three months—is generally advised, unless odors creep in sooner.

If your laundry room looks like a damp cave, or you suspect mold getting cozy, don’t wait—clean it sooner.

Sanitize Like a Pro: When to Step Up Your Game

Running a standard washing machine cleaner is great, but sometimes your machine needs a date with the big guns.

If you’ve been hit with illnesses in your household, or your freshly washed clothes smell less than fresh, it’s time for a thorough sanitizing cycle. Manufacturers and experts like Affresh recommend sanitizing as soon as odors or contamination issues surface.

Advanced washing machine cleaner products and sanitizers can kill bacteria and remove biofilms lurking inside your machine, killing the stink and health hazards alike.

Give It a Deep Clean Twice a Year

While monthly or quarterly maintenance keeps your washer in fine shape, don’t forget about the deep clean. According to The Home Depot, this should be done about every six months.

A deep clean involves more than just running a cleaning cycle. It includes scrubbing the gasket (yep, the rubber door seal), cleaning detergent dispensers, and wiping down the drum and door.

What Happens When You Skip Cleaning?

Ignoring washing machine cleaning is like skipping oil changes in your car—you might get away with it for a bit, but eventually, things fall apart.

Leaving residue can clog the filter, reduce washing efficiency, and even cause your machine to break down faster. More annoyingly, you might notice that your clothes come out dingy or smelling funky despite a full wash.

  • Empty pockets and pre-treat stains to reduce grime entering the drum.
  • Regularly wipe the rubber gasket and dispenser trays with a cloth to remove dirt.
