How to Clean a Washing Machine: A Step-by-Step Guide

To clean a washing machine effectively, run an empty cycle on the hottest water setting using two cups of distilled white vinegar or a specialized washing machine cleaning tablet to break down mineral buildup and soap scum. Follow this with a second hot cycle using half a cup of baking soda to neutralize odors. Finish by manually wiping down the rubber door gasket, soaking the detergent dispenser drawer, and clearing debris from the drain pump filter.

Why You Need to Clean Your Washing Machine Regularly

It is easy to assume that an appliance designed to wash clothes stays clean on its own. However, every load leaves behind a combination of detergent residue, fabric softener, body oils, pet hair, and dirt. Over time, this mixture creates a slimy biofilm inside the drum and internal hoses. Combined with the warm, humid environment inside the appliance, this residue becomes a breeding ground for mold, mildew, and foul odors.

Cleaning your washing machine on a monthly basis provides several key benefits:

Prevents musty, sour smells from transferring onto freshly washed garments.
Extends the operational lifespan of your washer by preventing pump and hose clogs.
Improves energy and washing efficiency by clearing hard water scale from heating elements and drum sensors.
Removes bacteria, mold spores, and allergen buildup from the interior drum and rubber seals.

Essential Supplies for Cleaning Your Washing Machine

You do not need expensive commercial products to get a deep clean, though commercial washing machine tablets are an effective alternative. Gather these basic household items before getting started:

Distilled white vinegar (or liquid chlorine bleach, but never mix the two together)
Baking soda
Mild dish soap
Microfiber cleaning cloths
An old toothbrush or small detailing brush
A shallow pan and towel (for draining the filter)

How to Clean a Front-Loading Washing Machine

Front-load washers are highly efficient, but their horizontal drum design makes them particularly prone to standing water, mildew, and smelly rubber gaskets. Follow these steps to restore your front loader.

First, inspect and clean the rubber door gasket. Pull back the folds of the rubber seal to expose trapped lint, hair, and slimy grime. Spray the area thoroughly with white vinegar or a mild bleach solution, then scrub away residue with a soft microfiber cloth or toothbrush. Wipe the seal completely dry when finished.

Second, run the deep-cleaning cycle. Pour two cups of white vinegar directly into the detergent dispenser tray, or place a washing machine cleaning tablet directly inside the empty drum. Select the "tub clean" cycle, or manually choose the hottest water setting with an extra rinse option. Let the cycle run completely.

Third, perform a deodorizing cycle. Sprinkle half a cup of baking soda directly into the drum and run another short, hot wash cycle. This step scrubs away loosened scale and neutralizes any lingering acidic vinegar smells.

How to Clean a Top-Loading Washing Machine

Top-loading machines hold a higher volume of water, allowing you to fill and soak the entire drum to dissolve built-up dirt and fabric softener deposits.

Start by setting your washer to its hottest temperature, largest load size, and longest cycle. Allow the tub to fill completely with hot water.

Once the tub is full, pause the cycle and add four cups of distilled white vinegar. Close the lid and let the machine agitate for two minutes to mix the solution evenly, then open the lid or pause the cycle again to let the water sit undisturbed for 45 to 60 minutes. This extended soak penetrates hardened detergent deposits and mineral scale.

While the water is soaking, use a microfiber cloth dipped in the warm vinegar water to scrub the top edge of the drum, the underside of the lid, and the area around the rim where water does not typically reach.

Close the lid and allow the wash and spin cycle to complete, draining the dirty water. Once finished, sprinkle one cup of baking soda into the bottom of the drum and run one more hot cycle to polish the stainless steel and eliminate odors.

How to Clean the Detergent Dispenser Drawer

Removable dispenser drawers frequently harbor hidden mold and gelatinous fabric softener residue. Neglecting this component can continuously contaminate the clean water entering your machine.

Press the release tab located inside or behind the dispenser drawer and pull it completely out of the machine housing.
Submerge the drawer in a basin of warm water mixed with a few drops of dish soap or vinegar.
Scrub the individual compartments, siphons, and corners using an old toothbrush to remove all residue.
Before reinstalling the drawer, spray inside the empty dispenser cavity on the machine and scrub the interior roof and walls to clear mold patches.
Rinse the drawer thoroughly, dry it with a towel, and slide it back into position.

How to Clean the Drain Pump Filter

Most modern front-load washers and some top-load washers include a drain pump filter designed to catch coins, buttons, lint, and hair before they damage the drainage pump. A clogged filter causes drainage issues, standing water, and strong odors.

Locate the small access door at the bottom front of your washing machine. Place a shallow tray and an old towel on the floor underneath the door. Unscrew the emergency drain tube cap (if equipped) to release trapped water, then slowly unscrew the main filter cap counterclockwise. Remove any collected debris, wash the filter screen under running warm tap water, inspect the interior pump cavity for obstructions, and screw the clean filter tightly back in place.

Preventative Habits to Keep Your Washer Fresh

Performing minor maintenance after every laundry day significantly reduces the frequency of deep cleanings and keeps your laundry room smelling fresh.

Leave the door open: Keep the washer door or lid cracked open between loads to allow airflow and evaporate trapped moisture.
Dry the gasket: Wipe the bottom folds of front-load gaskets with a dry towel after finishing your final load of the day.
Measure detergent accurately: Using too much liquid detergent or fabric softener creates excess suds that fail to rinse away, leaving a sticky coating on internal parts.
Use powder or vinegar alternatives: Liquid fabric softeners contain fats that coat drum walls; consider switching to wool dryer balls or adding half a cup of vinegar to the rinse cycle instead.
Remove damp clothes immediately: Never let wet laundry sit in a closed drum for hours, as this encourages rapid mold and bacteria growth.

Conclusion

Knowing how to clean a washing machine properly ensures that your clothes come out truly clean and odor-free every single time. By combining an automated hot vinegar and baking soda cycle with manual care for the gasket, dispenser, and drain filter, you can easily maintain peak machine performance. Spend thirty minutes once a month on this routine to protect your investment and keep your laundry smelling fresh.
