TL;DR
Seagrass is a rope-like natural fiber that soaks up water and dries slowly, so cleaning it is mostly vacuuming. Use a barely damp cloth only where you must, dry the basket in moving air right away, and never soak or hose it. Water inside the twist is what causes the musty smell.
What makes seagrass different from other woven baskets?
Seagrass is a marine plant fiber, harvested, dried, and twisted into a rope before it is woven. That twist is the key difference. Water wicks into the center of the twist and stays there long after the surface looks dry.
The fiber also has a natural waxy surface that resists light spills for a minute or two, which fools people into thinking it is water-tolerant. It is not. It just delays absorption briefly.
Seagrass has a characteristic hay-like smell when new, and that is normal. A sour or musty smell is different and means moisture has gotten in.
How do you clean a seagrass basket?
Vacuum inside and out with a soft brush attachment, following the weave direction. Spot clean marks with a cloth wrung out until it is barely damp, using water with a drop of mild soap, then dry that spot immediately with a towel. Air the basket until it is completely dry.

Vacuuming does most of the work here. Seagrass weaves have deep gaps that hold a surprising volume of dust, and no amount of wiping reaches into them.
Step by step
- Empty the basket and turn it upside down to shake loose debris out of the weave.
- Vacuum the interior, exterior, rim, handles, and the underside with a soft brush attachment.
- Work a dry soft brush along the twist to release packed dust, vacuuming behind it.
- For a stain, dampen a cloth with mild soapy water and wring it until it is nearly dry.
- Blot the mark rather than rubbing, working from the outside of the spot inward.
- Dry that section immediately with a clean towel, pressing rather than scrubbing.
- Set the basket in moving air, out of direct hot sun, until it is completely dry.
- Turn it once during drying so the underside dries too.
Blotting rather than rubbing matters on seagrass specifically. Rubbing frays the twist, and a frayed section looks lighter and rougher permanently.
How do you stop a seagrass basket from mildewing?
Keep it dry and give it airflow. Use seagrass in conditioned indoor rooms, not in bathrooms, basements, or garages. Do not store damp items in it, do not set it directly on a concrete floor, and dry it promptly and completely after any spill or spot cleaning.
Circulation matters as much as humidity. A basket packed tight against a wall in a closet has no airflow, and in a humid house that alone can be enough to start a smell.
Rotating baskets occasionally, so each one gets a few days in open air, is a small habit that solves most of this. So does emptying a basket completely once or twice a year rather than letting the bottom layer sit for years.
How do you get a musty smell out of seagrass?
Vacuum thoroughly, then set the basket outdoors in shade with good airflow for several hours, or indoors in front of a fan. If odor remains, seal it in a bag with an open container of baking soda for a few days. Avoid adding more water, which makes the problem worse.
Some gentle sun helps, but prolonged direct sun bleaches seagrass unevenly and makes it brittle, so limit it to an hour or two and keep the basket out of the hottest part of the day.
If dark growth has spread through the fiber rather than sitting on the surface, the basket is generally not recoverable. Growth inside natural fiber cannot be reliably removed, and continuing to treat it just spreads spores around the house.
Can you use cleaning products on seagrass?
Very little, and always diluted. A drop of dish soap in water on a barely damp cloth is enough for household marks. Skip strong degreasers, which strip the natural waxy surface and leave a dull patch, and skip anything that requires rinsing.
Do not use chlorine bleach on seagrass. It weakens plant fiber and lightens it unevenly, and the result looks worse than the stain did. Never mix bleach with any other cleaner either, since bleach plus ammonia releases chloramine gas and bleach plus an acid releases chlorine gas.
Fabric protector sprays marketed for natural fiber can help with new baskets in high-use spots. Test on the underside first, because some leave a visible sheen.
Where should seagrass baskets go?
Living rooms, bedrooms, closets, offices, and shelving in conditioned space. They are ideal for blankets, throws, toys, magazines, and shoes that are dry. The open weave breathes, which is genuinely better than a sealed bin for textiles that would otherwise go stale.
Avoid bathrooms and laundry rooms unless the basket has a removable washable liner. Avoid garages and basements outright, where the combination of humidity and temperature swings guarantees a problem.
Seagrass, rattan, and other woven materials share most of their care rules, so what works for a wicker basket generally works here. And in genuinely damp locations, both fail the same way fabric storage bins do.
How often should seagrass baskets be cleaned?
Vacuum monthly as part of your normal dusting circuit, and empty and clean thoroughly two to four times a year. Baskets that hold shoes, sports gear, or pet toys need more frequent attention because of grit and oils.
Grouping them into the dusting pass is what makes it happen. Baskets read as decor rather than as surfaces, so they get skipped until the dust is visible in the weave. That same batching approach is how the home object cleaning guide handles other easily forgotten items, including a magazine rack and its paper dust.
FAQ
Can you wash a seagrass basket?
No, not with immersion or a hose. Seagrass is a twisted natural fiber that absorbs water into its core and dries very slowly, which causes mildew, softening, and unraveling. Clean it by vacuuming and by spot cleaning with a barely damp cloth, drying each treated spot immediately.
How do you get stains out of seagrass?
Blot with a cloth wrung out in mild soapy water, working from the outside of the stain inward, then dry the spot right away with a towel. Do not rub, since that frays the twist and leaves a permanently lighter patch. Some stains on natural fiber will not fully lift, and light shadowing is normal.
Why does my seagrass basket smell?
A hay-like smell is natural and fades over time. A musty or sour smell means moisture got into the fiber, usually from a damp room, a spill, or damp contents. Vacuum it, dry it thoroughly with airflow, and move it to a drier location. Avoid adding more water.
Can seagrass baskets go outside?
Not for long. Rain, dew, and humidity all penetrate the fiber, and direct sun bleaches and embrittles it. A covered porch in dry weather is acceptable for short periods, but a seagrass basket left outdoors through a wet season will mildew and start to come apart.
How do you keep a seagrass basket from shedding?
Some shedding of short fiber ends is normal, especially when new. Vacuum regularly rather than brushing hard, keep the basket out of prolonged sun so the fiber does not become brittle, and add a fabric liner if it holds items that catch and pull on the weave.
Is seagrass or wicker better for storage?
They perform similarly, with seagrass usually softer and less prone to sharp broken ends, and rattan wicker usually more rigid and better at holding its shape when full. Both need dry indoor conditions. Choose based on look and stiffness, and use plastic wherever moisture is a real factor.
Should you line a seagrass basket?
A liner is worth adding whenever the basket holds clothing, linens, or anything small enough to catch in the weave. It protects the fiber from abrasion, keeps contents cleaner, and can be washed separately. For food or damp items, a liner is essentially required.
Woven storage looks great and quietly collects dust for years. If it is part of a larger reset, every home is different, so the real scope depends on your space, storage, and what you want covered. Our house cleaning services page has more, or get a quote and we will walk you through it.
