Learn how to effectively remove built-up scum from your washing machine using a simple scrubber. Follow these easy steps to get your appliance clean and fresh again.

To remove washing machine scum using a scrubber, you need to manually scrub away the accumulated residue from the drum, rubber seal, and detergent drawer using warm soapy water and a stiff brush. Follow up by running a hot maintenance cycle with white vinegar and baking soda to clear out any remaining looseness.

Washing machines work hard to clean our clothes, but over time, they accumulate a hidden layer of grime known as washing machine scum. This unpleasant buildup is a mixture of undissolved laundry detergent, fabric softener, body oils, dirt, and mold spores. It typically thrives in warm, damp environments, settling heavily inside the rubber door gasket, around the inner drum perforations, and within the detergent dispenser tray. Left unchecked, this scum causes persistent musty odors that transfer to freshly washed laundry, and it can even stain light-colored garments. Tackling this issue requires a hands-on approach, utilizing phys Nov 11, 2026 · Aug 30, 2025 · Buy Football Louisville Cardinals Football event tickets at Ticketmaster.com.

Gather your cleaning supplies before you begin, keeping everything straightforward and household-ready. You will need a sturdy hand-held scrubbing brush with firm bristles, a microfiber cloth, an old toothbrush for tight crevices, liquid dish soap, white vinegar, and baking soda. Protect your hands with rubber gloves, as the stagnant water and mildew hiding inside the machine can be harsh on the skin. Ensure the washing machine is powered off and unplugged before you start working near any internal components or electrical panels.

Examine the rubber door seal

Open the washing machine door and locate the rubber gasket surrounding the opening. This flexible ring is the primary trap for washing machine scum, hair, lint, and standing water. Gently peel back the folds of the rubber seal using your gloved fingers to inspect the hidden interior channels. You will likely see a dark, slimy residue accumulated along the bottom curves.

Spray the interior of the gasket liberally with a mixture of warm water and liquid dish soap, or a mild all-purpose cleaner. Take your scrubbing brush and work it carefully into the folds and crevices of the rubber, applying gentle pressure to lift the grime without tearing the delicate material. For the tightest corners and small drainage holes at the bottom of the seal, switch to the old toothbrush. Once the scum is loosened, wipe the entire area thoroughly with a damp microfiber cloth, removing all loosened debris and soap residue. Leave the washing machine door wide open when finished to allow this area to dry completely.

Remove the detergent dispenser drawer completely from the machine. Most modern washing machines feature a small release tab or button inside the softener compartment that allows you to pull the drawer straight out with a firm tug. Take the drawer to a nearby sink or basin to clean it thoroughly.

Spray the drawer with warm soapy water, paying close attention to the siphon caps and the upper compartments where sticky fabric softener and powder residue tend to bake onto the plastic. Use your scrubbing brush to scour every surface, working the bristles into corners and narrow channels where mold and gray scum settle. If there is stubborn, calcified mineral buildup or hardened detergent cakes, apply a paste of baking soda and water directly to the spots, let it sit for a short duration, and then scrub again. Rinse the drawer thoroughly under warm running water until all soap and debris are gone.

Scour the inner drum

Examine the stainless steel or porcelain drum of the washing machine. Look closely at the small drainage holes and the outer edges where the drum meets the back panel, as washing machine scum frequently forms a dull, greasy film over the metal surface.

If your machine is a front-loader, pay special attention to the glass on the inside of the door, as scum and soap film often dry onto this surface as well.

Scrubbing the entire drum manually requires patience, but physical friction is essential for removing the stubborn biofilm that routine detergent alone leaves behind. Once you have scrubbed the accessible interior surfaces, take a damp microfiber cloth and wipe down the drum to collect the loosened grime and soap suds, rinsing your cloth frequently in a bucket of clean water.

Fill a container with white vinegar and pour it directly into the empty drum, or add it to the main wash compartment of the detergent drawer. Baking soda can be added straight to the drum alongside the vinegar to create a mild effervescent reaction that helps lift remaining organic matter from unseen plumbing lines.

Select the hottest and longest wash cycle available on your machine's control panel, such as a sanitary cycle or heavy-duty setting. Ensure the water temperature is set to hot, as heat is required to melt away remaining greasy soap residues and sanitize the internal tub. Start the cycle and allow the machine to fill, agitate, and drain completely. The mechanical action of the drum spinning combined with the acidic properties of the vinegar will flush out loosened particles of scum from the internal pipes, pump, and filter that your brush could not reach.

Wipe down the exterior and seals

Finish the entire cleaning process by addressing the outer surfaces of the appliance. Dampen a microfiber cloth with warm soapy water and wipe down the control panel, the outer rim of the door, and the exterior housing of the washing machine to remove any drips, dust, or transferred grime from your cleaning session.
