That faint, closed-in smell drifting from a coat you haven’t worn since last winter, or the musty waft that hits when you open a suitcase stored in the spare room — is one of those small domestic irritations that feels oddly stubborn. The good news is that you can remove musty smell from clothes naturally, without reaching for heavily perfumed fabric softeners or chemical sprays that simply mask the problem rather than solve it. What follows is a practical, textile-respectful guide that works just as well for people with sensitive noses or allergies as it does for anyone who simply prefers a gentler approach to laundry.
Understanding Where That Musty Smell Actually Comes From
Before you can tackle the problem properly, it helps to understand what you’re actually dealing with. That renfermé smell, that slightly damp, closed-in mustiness, isn’t just a matter of staleness. It’s biological. Clothes develop this odour when microscopic fungi and bacteria find the conditions they love: a little moisture, limited airflow, and darkness. A wardrobe kept in a cool bedroom wall, a damp cellar cupboard, or even a washing machine left with the door shut can all become the perfect incubator.
The scenario most of us recognise is the “forgotten laundry” problem. You leave a load in the drum overnight, and by morning, even clean clothes have developed a mildly sour, musty edge. That’s not dirt, it’s mould spores and bacteria making themselves comfortable in the warm, damp conditions. Similarly, clothes packed away slightly damp, or stored in an airless box over summer, can emerge smelling as though they’ve been there for decades.
Why Strong Perfumes Make Things Worse
Reaching for a heavily scented dryer sheet or dousing clothes in fabric conditioner feels like a solution, but it’s really just decoration over the problem. The micro-organisms causing the smell are still there, you’ve simply added a floral layer on top. For anyone with respiratory sensitivities, hay fever, or skin allergies, strong synthetic fragrances can cause genuine discomfort. Babies, elderly people, and those recovering from illness often react badly to them too. The aim of truly removing the smell is to neutralise and eliminate the source, which is something that natural, unperfumed methods do rather well.
Natural Methods That Actually Work
White Vinegar: The Workhorse of Natural Laundry
White wine vinegar (the inexpensive distilled variety you’ll find in any supermarket) is probably the single most effective natural deodoriser for laundry. Its acidity disrupts the cellular structure of odour-causing bacteria and neutralises alkaline compounds from sweat and detergent residue that can themselves start smelling stale over time.
For a standard wash, add 100–150ml of white vinegar to the fabric softener compartment of your machine. Run the cycle as normal with your usual (unscented or lightly scented) detergent. The vinegar smell disappears almost entirely during the spin and drying stages, leaving clothes fresh and neutral rather than pickled. For particularly stubborn cases, soak the affected items in a basin of cold water with 250ml of white vinegar for 30–60 minutes before washing. Cotton, linen, and synthetic blends respond very well to this treatment. Do be cautious with elastic and rubber trims, repeated vinegar soaking can degrade them over time. For a broader look at how vinegar fits into a full laundry routine, the collection of natural laundry hacks is well worth reading alongside this guide.
Bicarbonate of Soda: Gentle, Dry, and Surprisingly Powerful
Where vinegar works in water, bicarbonate of soda earns its keep as a dry deodoriser, which makes it ideal for items you can’t easily wash, like a jacket, a knitted jumper, or a vintage piece you’re nervous about soaking.
Sprinkle a generous amount of bicarbonate directly onto the garment, press it gently into the fabric, and leave it to sit for several hours, overnight if possible. Then shake it off thoroughly and, if the item is washable, follow up with a normal wash. For storage freshness, a small open dish of bicarbonate placed inside a wardrobe or storage box acts as a quiet, continuous deodoriser that absorbs moisture and odours without adding any scent of its own. Two tablespoons added to a machine wash alongside detergent also helps freshen a full load.
A tip that often gets overlooked: bicarbonate works especially well on remove sweat stains naturally when combined with a little lemon juice to form a paste, which is useful if your musty-smelling item also has yellowed underarm areas.
Fresh Air and Sunlight: The Oldest Trick in the Book
There’s a reason our grandmothers hung everything on the line regardless of temperature, and science supports them entirely. UV light from direct sunlight kills mould spores and bacteria with impressive efficiency, no chemicals, no cost, no effort beyond carrying clothes outside. Even on a cool, overcast British day, airflow alone goes a long way towards dispersing the musty compounds clinging to fibres.
For best results, turn garments inside out to protect colour, and leave them outside for at least three to four hours. A breezy day will always outperform a still, sunny one when it comes to odour removal. If outdoor drying isn’t possible, hanging clothes near an open window or in a well-ventilated room for 24 hours achieves a remarkable improvement on its own. This costs nothing and leaves no residue whatsoever.
Lemon: Subtle, Effective, and Kinder Than You Might Think
Fresh lemon juice contains citric acid, which has mild antibacterial properties and gently brightens fabric at the same time. Add the juice of one or two lemons (or 3–4 tablespoons of bottled lemon juice) to a cold-water soak for white and light-coloured cottons. Leave for 20–30 minutes, then wash as normal.
Lemon is best kept for cotton and linen, avoid it on wool, silk, or brightly coloured garments, as the acid can affect dyes and delicate protein-based fibres. It works particularly well in combination with sunlight: lemon juice activated by UV produces a gentle bleaching effect that also happens to neutralise odour compounds. Those interested in taking this further can explore how to whiten clothes naturally without bleach using lemon and other household ingredients.
Coffee Grounds, Clay, and Activated Charcoal
These three might sound like they belong in a beauty column, but each has genuine deodorising properties worth knowing about. Dried used coffee grounds placed in a small breathable cloth bag (an old sock works perfectly) inside a storage box will absorb odours over several weeks. They won’t wash out of fabric, so keep them as a storage remedy rather than a washing one.
Absorbent clay (the unscented kind sold for cat litter, or cosmetic-grade bentonite) works on the same principle and can sit in a wardrobe drawer to prevent musty smells from developing. Activated charcoal granules, available in garden centres or health food shops, are perhaps the most powerful of the three, a handful in a small container inside a storage trunk will absorb moisture and odour compounds for months.
What to Avoid (and What Might Surprise You)
Protecting Delicate Textiles
Wool, cashmere, silk, and acetate require a gentler hand. Vinegar in small quantities (50ml in a cool hand-wash basin) is generally safe for wool, but hot-water soaks and long exposure times are not. Bicarbonate is low-risk for most fibres when used as a dry treatment, but avoid leaving it on silk for extended periods. When in doubt, test on a hidden seam allowance first and wash at the temperature shown on the care label.
Counter-Productive Habits
Pouring undiluted essential oils onto clothes is a mistake many people make when trying to freshen things up naturally. Tea tree oil and eucalyptus do have antimicrobial properties, but they are highly concentrated and can permanently stain fabric, particularly cotton and linen. If you want to use essential oils, a couple of drops on a small cloth placed near (not on) garments in a drawer is sufficient.
Tumble drying musty clothes without washing them first simply bakes the odour into the fibres. And storing laundry in plastic bags while still warm from the dryer creates exactly the warm, moisture-trapping environment where mould spores thrive.
Prevention: The Simplest Part of All
Drying and Storing Properly
Clothes must be completely dry before they go into a wardrobe or drawer. This sounds obvious, but even slightly damp jeans folded and put away will develop a musty smell within 48 hours. If you’re drying indoors, make sure the room has adequate ventilation, a slightly open window makes a substantial difference. Cedar blocks or sachets of dried lavender placed in drawers and wardrobes help discourage moth activity and add a faint, pleasant scent without synthetic fragrance.
Keeping the Washing Machine Fresh
A machine that smells stale will transfer that smell directly to your laundry. Running an empty hot cycle (60°C or higher) with 200ml of white vinegar in the drum once a month keeps mould and bacteria under control. Leave the door and detergent drawer open between washes to allow the drum to dry out completely.

Frequently Asked Questions
Can you really remove a persistent musty smell without any fragrance?
Yes, and often more effectively than with perfumed products. Fragrance masks odour; the methods described here neutralise or physically remove the compounds causing it. A vinegar soak followed by outdoor drying will shift a smell that fabric conditioner has been failing to budge for weeks.
What if the smell comes back after washing?
Persistent smell that returns quickly usually points to the storage environment rather than the clothes themselves. Check the wardrobe or chest for signs of dampness, condensation on walls, or poor air circulation. Treating the garment while the environment remains damp is like bailing a leaking boat, you need to address the source. A dehumidifier in a particularly damp room can make a significant difference.
Do these methods work for all fabric types?
The short answer is mostly yes, with adjustments. Cotton, linen, and synthetics handle vinegar and bicarbonate well. Wool and silk need cooler temperatures and shorter exposure times. Dry treatments (bicarbonate, charcoal, clay) are the safest option for items you’re unsure about. When the care label says “dry clean only”, honour that, but a gentle airing outdoors is always safe.
