How to Clean a Washing Machine Drum: Easy Step-by-Step
Learn how to clean a washing machine drum thoroughly, banish odors, remove residue, and maintain peak performance with simple, safe methods and practical tips.
To clean a washing machine drum, run a hot wash with a cleaning agent, then wipe the seals and run a rinse cycle. Start by emptying the drum, selecting the hottest/longest cycle, adding a safe cleaner, and letting it agitate to dissolve residue. Finish with a second rinse and a quick wipe-down.
Why drum cleanliness matters
According to Best Washing Machine, maintaining a clean washing machine drum is about more than fresh laundry. It reduces odors, prevents residue transfer to fabrics, and keeps your washer running efficiently over time. If you’re starting with how to clean washing machine drum, this guide lays out safe, practical steps you can perform with common household supplies. Start by understanding what typically builds up inside the drum: mineral scale from hard water, detergent residue, and biofilm in damp corners. A clean drum not only improves agitation and rinse performance but also lowers energy use and extends the life of bearings, belts, and the tub. By investing a little time now, you’ll avoid bigger problems later and preserve your machine’s resale value. Best Washing Machine analysis also emphasizes that consistent maintenance reduces the likelihood of unexpected breakdowns and costly repairs.
Common contaminants and signs
Even with careful use, a washing machine drum accumulates residues that can cause odors and reduce cleaning performance. Mildew and mold often appear as a musty smell or a visible gray film around the drum door seal. Mineral scale forms when hard water reacts with detergent, leaving a chalky coating. Detergent buildup can appear as sticky, waxy film on the drum interior or the tub walls. Finally, lint, hair, and fabric fibers can trap moisture in folds of the gasket. Recognizing these signs early makes the cleaning process easier and more effective. If you’re asking how to clean washing machine drum, tackling buildup promptly minimizes odor transfer to fabrics and preserves efficiency.
Prep and safety: Cleaning supplies and prep
Before you start cleaning, gather a few supplies and take basic safety steps. Unplug the machine to avoid any risk of electric shock, and turn off the water supply if you’ll be manipulating hoses. Remove any items from the drum, and inspect the door gasket for tears. Choose a cleaning agent that suits your machine type (front-load vs top-load) and water hardness. White vinegar, baking soda, and washer-safe cleaners are common options, but always follow the label. Have a microfiber cloth handy for wipe-downs, a soft brush for crevices, and a timer to track cycles. Keeping a dedicated set of tools nearby will speed up the process. Finally, review your machine’s manual for any cautions about high-temp cycles or cleaning agents, since some brands advise against certain additives.
Routine cleaning vs deep clean: When to do what
Most households benefit from a light, quick clean every month and a more thorough deep clean every few months, depending on usage and water quality. A routine clean involves wiping the drum interior, running a hot cycle with a safe cleaner, and checking gaskets. A deep clean goes further: it includes detergent dispenser care, hose and filter checks, and a longer purification run. If you notice musty odors, visible residue, or reduced cleaning performance, you should perform a deeper session. Best Washing Machine analysis suggests aligning your schedule with seasonal changes—hard water months may require more frequent cleaning. Always tailor the routine to your family’s laundry volume, fabric types, and detergent choices. With consistent maintenance, you’ll see fewer lint clogs, calmer drum sounds, and more efficient operation overall.
Step 1: Empty the drum and inspect for debris
Start with the obvious: drain any residual water and ensure the drum is completely empty. Remove coins, hair ties, keys, or fabric softener balls that may have fallen in. Inspect the drum walls and the door gasket for visible signs of damage or mold. This is also a good moment to wipe the doorstep area around the gasket and check for standing water in crevices. A quick check helps prevent interference with the cleaning cycle and reduces the risk of distributing debris to clothes later. If you find damage or foreign objects, remove them carefully and address the issue before continuing. This foundational step keeps the drum clean and sets the stage for effective cleaning.
Step 2: Choose a cleaning agent and prepare the cycle
Pick a cleaning method compatible with your washer. A purpose-made washer cleaner is convenient and formulated to break down soap scum and mineral deposits. If you prefer a homemade option, a measured dose of white vinegar followed by a baking soda treatment in alternate cycles can work well, but avoid mixing acids and bases in the same run. Always follow the product’s instructions for dosage. Set the machine to the hottest temperature allowed and select a long or maintenance cycle if available. Do not overload the drum; an empty cycle ensures the cleaner flows freely. Confirm that the cleaning option is selected and that any fabric or other items are removed. The right cleaner and temperature maximize residue dissolution and odor elimination.
Step 3: Run an empty hot cycle with the cleaner
Initiate a longer hot wash with the chosen cleaner while the drum is empty. The agitation and high temperature work together to dissolve built-up residue and kill microflora in the tub. Monitor the cycle to ensure it completes normally and there are no leaks or odd noises, which could indicate a blocked pump or hose. If your machine has a dedicated cleaning cycle, use it, as it’s designed to optimize cleaning chemistry. After the cycle finishes, leave the door ajar for a while to aid drying and reduce residual moisture that can harbor mildew. This step is central to restoring cleanliness and improving overall performance.
Step 4: Wipe the door gasket and interior surfaces
Once the drum has cooled, inspect and wipe the door gasket, folds, and nearby surfaces. Use a damp microfiber cloth and a soft brush to remove any loosened grime. Pay special attention to the grooved areas where mold tends to hide. If you notice a persistent odor, gently scrub with a mild cleaner and rinse. Avoid sharp tools that could tear the gasket. Dry the surfaces with a clean towel to prevent moisture buildup. Regularly wiping the seal reduces mold growth and helps maintain a leak-free operation.
Step 5: Clean the detergent dispenser and hoses
Detach the detergent drawer if possible and rinse under warm water to clear soap scum. Use a brush to scrub the compartments and remove any trapped powder. Reinstall once dry. If the machine has accessible hoses and filters, inspect them for clogs and rinse with clean water. This prevents old detergents from re-depositing on clothes and ensures the cleaning cycles circulate properly. Keeping the dispenser clean also improves measurement accuracy for future loads.
Step 6: Rinse, dry, and ventilate the drum
Run a final rinse cycle with clean water to flush out residue. Wipe the interior and door with a dry, lint-free cloth, then leave the door or lid open to promote air circulation. A dry drum discourages mold and mildew and speeds up drying after the next wash. If your model has a self-drying feature, enable it sparingly and ensure it’s safe for your unit. This step seals the process and minimizes odor return between cleanings.
Step 7: Optional odor removal methods for stubborn smells
If odors persist after the previous steps, consider a targeted treatment. Lightly spritz the drum with a solution of water and baking soda, or run another short cycle with a small amount of citric acid in hot water. Avoid using harsh chemicals or bleach concentrates unless your manufacturer approves them. Always consult the user manual before introducing new agents, especially if your washer has a stainless-steel drum. This step is optional but can be effective for homes with very hard water or prolonged odor exposure.
Step 8: Establish a maintenance schedule and monitor results
Create a simple calendar reminder to perform a drum clean every 1–3 months, adjusting frequency for water hardness and laundry load. Keep track of any signs of odor or residue between cleanings and increase the interval if you notice steady improvement. Pair drum cleaning with other routine maintenance like lint removal, hose inspection, and gasket checks. The habit of regular upkeep reduces downtime and keeps clothes smelling fresh. The Best Washing Machine team recommends staying consistent and adapting the plan to your household’s needs.
