How to Clean a Washing Machine and Remove Mold Quickly

If your washing machine smells funky or you spot mold on the door seal, it’s definitely time for a deep clean. Mold loves to grow when moisture, dirt, and leftover soap hang around inside. The fastest way to tackle mold in your washing machine is to use hot water and either vinegar, bleach, or a washer-specific cleaner—then leave the door open so it can dry out.

Mold is a pain because it comes back fast if you let your washer stay damp. Wiping the seal now and then and running a cleaning cycle every month really helps. Just a few extra minutes here and there can keep nasty smells and gunk from taking over.

You don’t need special skills to get your washer sparkling again. With some basic supplies and a bit of elbow grease, you’ll kick mold to the curb and keep your machine humming along. So, how do you actually do it? Let’s get into the details.

Why Mold and Mildew Develop in Washing Machines

Mold and mildew thrive inside washing machines because moisture, warmth, and leftover soap combine to create the perfect breeding ground. When you know where and why mold forms, it’s a lot easier to keep your washer clean and fresh.

Common Causes of Mold

Your washer stays damp inside after a load, especially around the rubber seal or in the drum. When water just sits there, mold gets comfortable.

Using too much detergent—or the wrong kind—leaves a sticky residue. That soap scum is basically food for mold, especially in front loaders with tight seals and less water.

Shutting the door right after a wash traps moisture inside. No airflow means a dark, humid playground for mildew.

Areas Most Affected

The rubber seal or gasket around the door is the main trouble spot. Water and detergent get caught in its folds, turning it musty fast.

The washer drum holds on to moisture, too—especially if you forget a load or the drum can’t dry. Mold doesn’t need much to get going on those damp surfaces.

Detergent dispensers are sneaky. They trap soap and water in little corners that never seem to dry out, so mildew can start there and stink up your clothes.

If you keep an eye on these spots, you’ll catch mold before it’s a problem.

Essential Supplies for Cleaning a Washing Machine

To really get your washer clean and mold-free, you’ll want a few basics: some natural cleaning agents, a commercial cleaner or two, and some simple safety gear.

Eco-Friendly Cleaning Agents

White vinegar and baking soda are my go-to’s for cleaning a washing machine. Vinegar kills mold and helps break up detergent gunk. Baking soda knocks out odors and stubborn buildup. For a front-loader, use about 2 cups of vinegar; for a top-loader, bump it up to 4 cups—just pour it in and run a hot cycle.

An all-purpose cleaner works for wiping surfaces like the door gasket or detergent drawer. Just make sure it’s safe for your machine and skip anything too harsh.

Recommended Commercial Cleaners

Tablets like Affresh are made for washers and dissolve away dirt, soap scum, and odors. Popping one in once a month keeps your washer smelling decent—no fuss.

You can use a bleach solution now and then, especially for the rubber seal. Just don’t forget to run an extra rinse to clear out any leftover bleach.

Safety Precautions

Open a window or switch on a fan when you clean with vinegar, bleach, or tablets. Gloves are a smart idea, too—nobody likes irritated skin.

Never mix bleach with vinegar or baking soda. That combo can release dangerous fumes. Always double-check the label and measure things out so you don’t wreck your washer or hurt yourself.

Step-by-Step Cleaning Instructions

Here’s how I keep my washing machine fresh and mold-free. Start by prepping, then clean the gasket, drum, and detergent drawer—don’t skip any steps if you want the best results.

Preparing the Washing Machine

First, empty your washer. Take out any clothes or random socks. Crack the door open for a bit to let the inside air out.

Grab what you’ll need: white vinegar, baking soda, a soft cloth or sponge, and gloves if you’re not into grime on your hands. Vinegar and baking soda are safe and effective for breaking down dirt and killing mold.

Pick the hottest setting on your washer for the cleaning cycles. If you’re cleaning by hand, unplug the machine just to be safe.

Cleaning the Gasket and Rubber Seal

The gasket and rubber seal on front-loaders are mold magnets. Wipe off loose dirt with a damp cloth.

Soak a cloth in equal parts water and vinegar (or a mild bleach mix), then wipe all around the rubber seal. Get into the folds—mold loves to hide there.

Gently pull back the seal and look for trapped gunk or water. Use a brush or cloth to clean inside, then dry the seal thoroughly with a towel. Moisture left behind just invites more mold.

Washing the Washer Drum

Pour 2 cups of white vinegar into the detergent dispenser. Run the hottest, longest cycle you’ve got—no clothes, just vinegar.

After that’s done, toss half a cup of baking soda right into the drum. Run another hot cycle. This tag team knocks out residue, odors, and mold.

If your washer has a cleaning cycle, use it. Doing this every 30 loads or so keeps things in check.

Sanitizing the Detergent Drawer

Detergent drawers get nasty fast. If you can, pop the drawer out. Let it soak in warm water with a splash of vinegar or some mild soap.

Scrub each compartment with a brush or cloth. Don’t forget to clean inside the slot where the drawer slides in—the water flows through here and mold loves it.

Rinse the drawer well and let it dry before putting it back. Leaving the drawer open a crack after each wash helps keep mold away.

Removing Mold From Hard-to-Reach Areas

Mold sneaks into the tightest spots. If you want a truly fresh washer, you’ve got to go after these hidden areas.

Deep Cleaning Behind the Washer Door

The seal inside the washer door traps moisture—a mold paradise. Gently pull back the rubber seal and wipe inside with a cloth soaked in vinegar or a mold cleaner.

After wiping, run an empty hot wash (about 60°C) with a cup of vinegar or machine cleaner to flush out any hidden spores and smells.

Make sure the seal dries out after cleaning. Seriously, just leave the door open when you’re done. Mold hates fresh air.

Treating Persistent Mold Spots

If mold keeps coming back in the same places, you’ve got to get aggressive. Spray a mold killer or a bleach and water mix on the area. Let it sit for 10-15 minutes—don’t rush it.

Scrub gently with a brush or cloth to remove dead mold. Don’t go overboard and damage the parts, though.

Afterward, run a hot cycle with a cup of vinegar or a washing machine cleaner. This helps clear out any leftover spores hiding in cracks.

Check these spots regularly and jump on any new mold before it spreads.

Running a Cleaning Cycle

A proper cleaning cycle does wonders for removing mold, smells, and buildup. It’s all about using the right settings and cleaner.

Choosing the Right Setting

Go for the hottest water setting on your machine. Hot water kills mold and bacteria. If your washer has a cleaning cycle, use it—it’s made for this job.

No cleaning cycle? Just run the longest, hottest wash you can. And don’t put clothes in during these cycles.

Using Cleaners Effectively

Add a cup of white vinegar or a washer cleaner to the detergent dispenser before starting. These break down mold and soap scum without messing up your machine.

If you’re into homemade solutions, mix equal parts vinegar and water and pour it in. Don’t go overboard on detergent—especially if you use HE detergent. Too much just leaves more residue for mold to munch on.

Deodorizing and Maintaining a Fresh Washing Machine

Want your washer to always smell fresh and clean? It’s easier than you think. A few habits and a cleaning schedule go a long way.

Preventing Unpleasant Odors

Leave the washer door open after every load. Letting it air out keeps the drum dry and mold at bay.

Wipe down the rubber gasket and detergent tray regularly with a mix of water and vinegar. That’s where soap and dirt hide.

Don’t let wet clothes sit in the washer. That’s just asking for mold and bad smells.

Run a hot cleaning cycle with a washer cleaner or natural deodorizer every month. It breaks down buildup and keeps things smelling good.

Scheduling Regular Maintenance

Check your washer’s manual for cleaning cycles and recommended products. Some washers have a dedicated cleaning button—use it.

Plan to clean the detergent drawer, gasket, and drum every month or two. Vinegar, mild soap, or machine cleaner all work.

If you spot mold or stubborn odors, use a cleaner tablet or a bit of bleach. Always follow the manual so you don’t mess anything up.

Stick to a routine and you’ll avoid the worst of the mold drama.
