It’s possible to refresh your washer by cleaning the drum. This guide shows you how to prep, choose cleaners, run a drum-clean cycle, and verify results, with safety tips and a maintenance plan to prevent buildup. Follow these steps to guard against odors, mold, and residue in daily use.
Why drum cleaning matters
Keeping the washing machine drum clean is more than a cosmetic task—it directly affects hygiene, appliance performance, and the longevity of seals and hoses. Over time, mineral deposits, soap scum, and mold can accumulate inside the stainless steel drum and along the rubber door seal, leading to musty odors and less efficient cleaning. If you’re unsure what to do for washing machine drum clean, starting with a simple wipe-down and a regular maintenance routine can make a big difference. This section explains why a clean drum matters for your laundry routine in 2026 and beyond, and how a few deliberate steps can prevent odor, residue, and fabric complaints.
Common causes of drum odor and residue
odors and residue in the drum stem from a few repeat culprits: mineral build-up from hard water, soap and detergent residue, fabric softener deposits, and mold growth in gaskets and folds. These issues can accumulate quietly and release unpleasant odors as you wash. The bulk of buildup tends to collect in hard-to-reach areas such as the drum lip, the seal, and the hose paths behind the drum. Understanding these causes helps you target the right cleaning approach and avoid over-cleaning with harsh chemicals.
Before you start: safety and prep
Safety comes first. Always unplug the machine before you begin any interior cleaning. Remove any loose items from the drum and detach the detergent drawer to access the cavity behind it. Have your cleaning supplies ready, including gloves and an absorbent towel, so you can catch splashes and wipe up spills. Checking your user manual for any drum-cleaning cautions is wise, as some models have specific recommendations or warnings about aggressive cleaners.
Quick-win cleaning methods
If you want fast results, start with a quick wipe-down: dampen a microfiber cloth and wipe the drum interior, the rim, and around the door seal to remove visible residue. Then run a hot cycle with no clothes, using a simple cleaner like white vinegar or a ready-made washer cleaner. This 1- to 2-step approach can eliminate odor-causing residues in under an hour, making it a practical starter method while you gather supplies for deeper cleaning.
Deep cleaning with vinegar and baking soda
For a deeper drum clean, combine white vinegar and baking soda in the drum. A common approach is to pour two cups of white vinegar into the drum and add half a cup of baking soda directly inside. Run a hot water cycle with the drum empty, pause midway to scrub the door seal and interior grooves, then resume the cycle to complete the wash. This combination helps dissolve mineral buildup and neutralize odors without harsh chemicals. Remember: never mix vinegar with bleach.
Using a commercial drum cleaner
If you prefer a commercial option, choose a washer-safe drum cleaner and follow the product directions. Most cleaners are added to an empty drum and run through a hot cycle. Afterward, run an extra rinse to flush residues. Commercial cleaners can be effective for stubborn buildup and may be a good choice for households with older machines or hard water. Always read the label for compatibility with your model and gasket materials.
Cleaning the door seal and detergent drawer
Odors often originate from mold and residue around the door gasket and in the detergent drawer. Wipe the gasket folds with a damp microfiber cloth, paying attention to creases where water collects. Remove and clean the detergent drawer separately, rinse it thoroughly, and dry before re-inserting it. A quick weekly wipe-down of these areas helps prevent future buildup and keeps your washer smelling fresh.
Rinse, dry, and air-out for best results
After any cleaning cycle, run an extra rinse to ensure all cleaner residues are flushed away. Leave the door or lid slightly ajar for a few hours to air-dry the drum and seal; this reduces dampness that can foster mold. If you see standing water in the drum or around the seal, wipe it dry with a towel and allow the machine to finish drying before the next use. A dry environment limits odor recurrence.
Maintenance plan to prevent future buildup
Create a simple monthly maintenance routine to prevent future drum buildup. This can include a hot-cycle drum clean every 1–3 months, depending on usage and water hardness. Keep a small supply of microfiber cloths and a dedicated cleaning brush nearby for quick touch-ups. Tracking your cleaning schedule in a calendar helps you stay consistent and extend the life of your washer.
Troubleshooting common issues after cleaning
If odors linger after cleaning, inspect the door gasket for hidden mold, and check the drain pump and filter for blockages. If the drum still smells, repeat a hot cleaning cycle with vinegar or a dishwasher-safe cleaner and verify there are no leaks or standing water in the drum area. For persistent issues, consult a professional technician to assess seals and hoses for wear or damage.
What to do if odor persists or stains remain
When odor or stains persist despite cleaning, you may be dealing with deeper mold growth or seal deterioration. Consider running multiple maintenance cycles, using a specialty mold cleaner, and inspecting the rubber gasket for cracks. If the problem continues, arranging a service visit might be necessary to prevent long-term damage and maintain efficiency.

Steps
Estimated time: 60-75 minutes
- 1
Power down and unplug
Turn off the washer and unplug the power cord to avoid any electrical hazard during cleaning. This simplification helps you handle internal components safely. If your model has a built-in drain, disconnect only after you’ve spaced steps that require it. Make safety your first step to prevent accidents.
Tip: Always start with power off and unplug before removing any parts. - 2
Remove detergent dispenser
Carefully pull out the detergent drawer to access the drum area behind it. This gives you a chance to rinse and wipe the cavity and remove leftover soap or softener deposits that can contribute to odors.
Tip: Take the drawer to a sink for a quick rinse to prevent drips on the floor. - 3
Inspect drum for objects
Look inside the drum for any coins, hair ties, or foreign objects that could cause noise or damage. Removing these items helps prevent jams and ensures a smooth cleaning cycle.
Tip: Use a flashlight if needed to see into the drum edge and seal area. - 4
Wipe interior with microfiber
Wipe the drum and the interior of the door seal with a damp microfiber cloth to remove visible residues. This quick wipe reduces the amount of grime that vinegar and baking soda must break down later.
Tip: Rinse the cloth frequently to avoid redistributing grime. - 5
Pour vinegar into drum
Pour two cups of white vinegar into the empty drum to loosen mineral buildup and deodorize. Vinegar is safe in moderation and works well for lightening odor-causing residues.
Tip: Do not combine vinegar with bleach or any chlorine cleaners. - 6
Add baking soda to drum
Add 1/2 cup of baking soda directly into the drum. The baking soda helps neutralize acids and lift residue, improving the cleaning action of the hot cycle.
Tip: Avoid adding baking soda in the detergent drawer; it should go directly in the drum. - 7
Run hot cycle with clothes removed
Program the washer to run a hot wash cycle with no clothes and allow the drum to fill and agitate. The heat helps dissolve remaining residue and the vinegar fragrance dissipates.
Tip: If your machine lacks a true hot setting, use the warmest available option. - 8
Pause mid-cycle to scrub seals
When the cycle pauses, inspect and scrub the door seal and groove with a brush to remove any remaining grime. Reclose and resume the cycle to finish the cleaning.
Tip: A paused mid-cycle window ensures you reach tight spots you might miss otherwise. - 9
Rinse cycle and air-dry
Run an extra rinse to flush away all residues from vinegar and baking soda. Leave the door ajar after washing to air-dry the interior and prevent dampness.
Tip: Ensure the drum is completely dry before your next load. - 10
Wipe gasket and drawer area
Wipe the door gasket edges and the detergent drawer cavity to remove any residual moisture. Drying these parts reduces the chance of mold growth between uses.
Tip: Keep a small towel handy for quick wipe-downs after every wash. - 11
Dry and store cleaning tools
Dry all tools and store them in a designated cleaning kit for easy access. Ready-to-use tools reduce setup time for the next drum-clean session.
Tip: Reserve a corner of the laundry area for cleaning supplies. - 12
Leave the door ajar to air-dry
After cleaning, leave the door or lid slightly open to allow air circulation and thorough drying. This practice minimizes mold and keeps odors at bay for the next wash.
Tip: AIRING OUT is an easy, effective maintenance habit.
