TL;DR
A hamper that smells like old towels has a moisture habit, not a dirt problem. Damp towels and sweaty clothes sit in an unventilated container and mildew within a day or two. Wash the liner, clean the shell by material, and stop putting anything wet in there.
Why does a laundry hamper smell musty?
Because damp textiles in a closed container are ideal conditions for mildew. A wet towel tossed in on Monday keeps the fabric around it damp all week, and the smell you notice is the byproduct of that microbial growth on the fibers.
Sweat adds to it. Body oils and bacteria on worn clothing break down over days, producing sour odors that transfer into the hamper's liner and, on a plastic or woven shell, into the material itself.

That is why the smell is worst in bathrooms. High humidity means nothing in the hamper ever fully dries.
How do you clean a laundry hamper?
Remove and machine wash the liner in hot water if the tag allows, adding oxygen bleach for mildew odor. Wash the shell by its material: plastic gets soap and water, metal gets a damp wipe and dry, and woven or wooden shells get vacuumed and only lightly damp wiped. Dry everything completely.
The order matters. Liner in the machine first, then the shell, then reassemble only once both are bone dry. A liner returned to a damp shell restarts the whole problem immediately.
Step by step
- Empty the hamper completely and start a laundry load with the contents.
- Take the liner out and check its care tag.
- Wash the liner in the hottest water the tag allows, with detergent and oxygen bleach for musty odor.
- Vacuum the inside of the shell to remove lint and hair.
- Clean the shell by material, using the guidance below.
- Dry the shell in sun or moving air, and dry the liner fully rather than leaving it damp.
- Wipe the floor where the hamper sits, which collects lint and dust.
- Reassemble only when both parts are completely dry.
Lint is the hidden part of this job. Hampers accumulate a surprising amount of fiber, hair, and pocket debris in the base, and it holds odor along with everything else.
How do you clean each hamper material?
- Plastic: wash inside and out with hot water and dish soap, rinse, and dry. This is the easiest material and the most forgiving, much like plastic storage totes.
- Coated wire or metal: wipe with a soapy cloth, rinse with a damp cloth, and dry immediately so the coating does not chip and rust underneath.
- Wicker, rattan, or seagrass: vacuum the weave, then wipe with a barely damp cloth and dry fast with a fan or sun. Never soak, since natural fiber holds water and mildews from the inside. The same caution applies to a wicker basket used for storage.
- Canvas or fabric collapsible: check for a cardboard or plastic stiffener before washing. Fabric with a removable stiffener can go in a cold gentle cycle; fabric bonded to cardboard must be spot cleaned only.
- Bamboo or wood: damp wipe and dry immediately. Standing moisture raises grain and can loosen glued joints.
For any woven or wooden hamper in a bathroom, a removable washable liner is the practical solution, because the shell itself will never tolerate the cleaning the contents demand.
How do you get the mildew smell out for good?
Wash the liner in hot water with oxygen bleach and let it dry completely in sun if you can. Then change the habit: hang wet towels to dry before they go in, and never put damp workout clothes straight into a closed hamper. Ventilation and dryness solve what cleaning alone cannot.
Oxygen bleach is a peroxide-based powder and is safe on most colors, unlike chlorine bleach. Do not use chlorine bleach on colored liners, and never combine it with any other cleaner, since bleach plus ammonia releases chloramine gas and bleach plus an acid releases chlorine gas.
If a musty smell persists in the room after the hamper is clean and dry, look at the wall, floor, and baseboard behind it. Visible black growth on building surfaces is a moisture and remediation issue, which is a separate trade from cleaning.
What kind of hamper stays cleanest?
Ventilated ones. A hamper with open slats, mesh panels, or a woven weave lets moisture escape, which slows mildew significantly compared with a sealed plastic bin with a tight lid.
Two-compartment hampers help in a different way, because sorting at the source means clothes move to the machine faster instead of sitting. And a removable, machine-washable liner turns the whole maintenance job into one laundry load.
Avoid a lid in a humid bathroom. It traps exactly the moisture you need to release, and it is the reason bathroom hampers smell worse than bedroom ones with identical contents.
How often should a hamper be cleaned?
Wash the liner monthly and wipe the shell at the same time. Move to every two weeks for a bathroom hamper, a shared hamper, or a household with sports gear. Do it immediately any time something genuinely wet goes in.
Making it part of a normal laundry day is what makes it stick. The liner goes in with towels, the shell gets wiped while that load runs, and both dry together. The home object cleaning guide uses that same attach-it-to-an-existing-routine idea for other overlooked items.
FAQ
Can you wash a hamper liner in the washing machine?
Usually yes. Most fabric liners are cotton or polyester and wash in hot water with regular detergent. Add oxygen bleach for musty odor. Check the tag first, since some liners have a coated or laminated backing that should be washed cold and air dried instead of tumbled.
How do you get the smell out of a plastic laundry hamper?
Wash it inside and out with hot water and dish soap, scrubbing the base and any ridges where lint packs in. Rinse, then dry it in sun if possible, since sunlight and complete drying both help. Deep-set odor in aging, softened plastic sometimes means it is time to replace the hamper.
Should you use a lid on a laundry hamper?
Generally no, especially in a bathroom. A lid traps humidity and slows drying, which is exactly what causes mildew smell. An open or ventilated hamper lets moisture escape. If you want a lid for appearance, choose one with vents and keep genuinely damp items out of the hamper entirely.
Can you put wet towels in a hamper?
You should not. A wet towel keeps everything around it damp for days and is the most common single cause of hamper odor. Hang towels to dry on a bar or hook first, then add them to the hamper once they are dry, or take them straight to the machine.
How do you clean a wicker laundry hamper?
Vacuum the weave with a brush attachment, then wipe with a barely damp cloth using mild soap and dry it immediately with a towel and a fan or sunlight. Do not soak or hose wicker, because natural fiber absorbs water, mildews internally, and can unravel as it swells and dries.
Does baking soda help with hamper odor?
It absorbs moisture and some odor between cleanings, so a small open container in the base helps as maintenance. It will not fix an existing mildew smell in fabric, which needs washing with hot water and oxygen bleach. Treat it as prevention rather than as a cure.
What if the hamper smells again a week later?
Something wet is still going in. Check for damp towels, workout clothes, or swimsuits, and check whether the room's humidity stays high after showers. Running the exhaust fan longer and switching to a ventilated hamper usually solves the recurrence when washing alone does not.
Laundry areas and bathrooms tend to develop odor problems in several places at once, and fabric storage bins nearby often have the same issue. Every home is different, so the real scope depends on your layout, ventilation, and what you want covered. Our house cleaning services page has more, or get a quote and we will walk you through it.
