How to Remove Stubborn Laundry Fragrance: 7 Gentle Things to Try

How to remove stubborn laundry fragrance can be a surprisingly difficult problem to solve, particularly when dealing with the intensely perfumed scents found in many modern laundry detergents and fabric conditioners.

This isn’t simply the faint smell of washing powder that disappears after a day on the washing line. Some fragrances have an almost aftershave-like intensity, lingering on towels, clothes and bedding long after they’ve been washed. They can even transfer between fabrics and leave a noticeable scent on the skin after handling them.

Anyone who has bought second-hand children’s clothes, inherited baby clothes or welcomed guests who use strongly fragranced laundry products may recognise the problem.

From personal experience, these fragrances can be so persistent that even repeated washing makes little difference. On occasion, I’ve reluctantly thrown things away because the smell simply wouldn’t shift.

But why are modern laundry fragrances so difficult to remove? Looking more closely at how these products are formulated reveals why simply washing something again isn’t always enough.

Why can laundry fragrance be so difficult to remove?

Modern laundry fragrance isn’t always simply perfume dissolved within a detergent or fabric conditioner.

Some products use fragrance microencapsulation: microscopic quantities of perfume are enclosed within a shell designed to help fragrance remain associated with fabric and release gradually after washing.

Researchers studying perfume microcapsules have shown that these systems can remain on textiles through repeated laundering. Friction can then rupture some of the remaining capsules, releasing fragrance again.

In other words, that strange moment when a supposedly clean towel suddenly smells strongly perfumed again after you rub it isn’t necessarily your imagination.

The fragrance may have been designed to persist.

That also means we need to be realistic about removing it. There probably isn’t one magic ingredient that will remove every modern fragrance formulation from every fabric.

How to remove stubborn laundry fragrance without simply covering it up

There are plenty of dramatic laundry “detox” recipes online. My preference is to start gently and give the fragrance the best possible opportunity to leave the fabric rather than trying to cover one scent with another.

1. Stop adding fragrance

This sounds obvious, but it’s the most important starting point.

Switch to an unfragranced detergent and don’t add fragranced fabric conditioner.

Also consider the washing machine itself. If strongly fragranced products have been used regularly, residues may remain around the detergent drawer, door seal and other areas of the machine.

Follow your machine manufacturer’s cleaning instructions and clean the detergent drawer and accessible seals before beginning. Otherwise you may unknowingly be reintroducing fragrance each time you wash.

2. For washable, robust fabrics, consider starting with a warmer full wash

Temperature is interesting when it comes to fragrance microcapsules. Research on commercial perfume microcapsules has found that some release considerably more fragrance during washing at higher temperatures than at 30°C. Heat also increases the volatility of many fragrance compounds.

That doesn’t mean a hot wash will magically destroy every fragrance capsule. Different encapsulation technologies behave differently, and some are deliberately designed to be remarkably heat-stable.

But if you’re dealing with something robust such as a cotton towel or cotton bedding, and the care label permits it, I would consider starting with a proper warm or hot wash rather than a cold, short or quick cycle. Use an unfragranced detergent and don’t overload the drum.

The care label comes first. Don’t increase the temperature beyond what the manufacturer recommends, particularly with synthetics, elastics, wool, silk, technical fabrics or delicate children’s clothing.

The aim isn’t simply to release the fragrance. We also need to give released fragrance and residues somewhere to go, which is why rinsing matters.

2. For washable, robust fabrics, consider starting with a warmer full wash

Temperature is interesting when it comes to fragrance microcapsules. The evidence we have suggests that heat can encourage some types of capsule to release more of their perfume. One study examining a commercial encapsulated perfume found that after one hour of laundering, perfume release at 60°C was approximately 1.5 times greater than at 30°C, while release at 80°C was around 3.1 times greater. The particular microcapsules studied had a temperature-responsive polymer shell, so we shouldn’t assume every fragrance capsule will behave in exactly the same way. You can read the study on temperature and commercial perfume microcapsules here.

Importantly, releasing more perfume isn’t necessarily the same thing as removing the fragrance system from the textile. If heat encourages fragrance to escape from a capsule, we still want detergent, plenty of water and effective rinsing to help carry released material away. For that reason, where the fabric’s care label permits it, I would favour a full warmer wash with unfragranced detergent followed by an extra rinse, rather than simply soaking or rinsing the item in hot water.

It’s also worth knowing just how resilient some fragrance microcapsules can be. In one textile study, experimental fragrance microcapsules applied to cotton demonstrated good washing durability even after 15 wash cycles. The capsules studied also showed good thermal stability below 100°C. You can read the published research in RSC Advances here.

Another textile study found microencapsulated perfume continued releasing aroma after as many as five dry-cleaning cycles, illustrating why persistent fragrance isn’t always something a single wash can solve. You can read that research in the Chemical Engineering Journal here.

None of this means that hotter is automatically better. Different fragrance capsules use different shell materials and release mechanisms, and heat can damage or shrink clothing long before it has solved a fragrance problem. Always follow the garment’s care label, particularly with synthetics, elastics, wool, silk, technical fabrics and delicate children’s clothing.

For a robust cotton towel or cotton bedding that permits a warmer wash, however, a proper wash at the highest appropriate care-label temperature, using an unfragranced detergent and followed by an extra rinse, is a sensible place to start.

3. Use an extra rinse

If your washing machine has an extra-rinse function, use it.

This isn’t about “flushing toxins” from clothing. It’s much simpler: if washing has loosened fragrance material or other residues, plenty of clean rinse water gives them a better opportunity to leave the fabric.

For particularly heavily fragranced clothing, I would favour a full wash and extra rinse rather than repeatedly relying on a short or quick-wash programme.

4. Try soaking stubbornly fragranced clothes

If repeated washing isn’t shifting the fragrance, soaking the item before washing can be worth trying. Two of the most commonly used household approaches are bicarbonate of soda and white vinegar.

I haven’t found good evidence showing that either specifically destroys modern fragrance microcapsules, so I wouldn’t describe either as a “detox” or a guaranteed microcapsule remover. But they are practical household approaches people use for managing stubborn odours, and soaking also gives water more time to penetrate the fibres before another wash.

For bicarbonate of soda, try dissolving around half a cup (approximately 100g) in a basin or bucket of warm water and soaking the clothing for several hours or overnight. Rinse thoroughly, then wash using an unfragranced detergent and, if possible, select an extra rinse.

Alternatively, try a white vinegar soak. Add around one cup (approximately 250ml) of plain white vinegar to a basin or bucket of cool or lukewarm water, soak the item for an hour or two, then rinse thoroughly and wash with an unfragranced detergent.

I would use these methods separately rather than mixing bicarbonate of soda and vinegar together. When an acid and bicarbonate are combined they react and largely neutralise one another. The fizz looks satisfyingly industrious, but it doesn’t necessarily make the mixture a better laundry treatment.

Always check the garment’s care instructions first. I’d be particularly cautious with wool, silk, delicate dyes, specialist finishes, elastics or anything precious.

And don’t be discouraged if one soak doesn’t completely remove the scent. With heavily fragranced second-hand clothes and towels, it may take a combination of soaking, washing, thorough rinsing and airing.

5. Give it air — sometimes lots of it

After washing, dry and air the item thoroughly.

If possible, hang it outside or somewhere with very good airflow rather than immediately tumble-drying it and putting it into a cupboard or drawer.

Some fragrance molecules are volatile, meaning they gradually move from the fabric into the surrounding air. Giving clothing time and ventilation can therefore help the smell diminish.

It may take longer than you expect.

I’ve found this particularly relevant with second-hand items where fragrance has probably accumulated through repeated use of strongly scented products.

6. Don’t judge it while it’s wet

The smell of laundry can change enormously between being wet, freshly dried and completely aired.

After washing, let the item dry completely and give it some time before deciding whether another treatment is necessary.

You may even notice fragrance becoming stronger again when you handle or rub the dry material. Some fragrance technologies are deliberately designed to release perfume through movement and friction.

If that happens, don’t assume your wash achieved nothing. It may simply mean that fragrance remains associated with the textile and another wash-and-air cycle is needed.

7. Be particularly patient with different fibres

Different fibres interact with fragrance compounds and laundry formulations differently, so two garments washed in exactly the same product may not behave identically.

If you’re dealing with children’s sportswear, school uniform, fleece, polyester bedding or other synthetic materials, don’t be surprised if they behave differently from a simple cotton sheet or towel.

I’d start with repeated fragrance-free washing, thorough rinsing and airing rather than immediately escalating to aggressive treatments that could damage the material.

How can I stop fragrance transferring onto other laundry?

If you’ve acquired a particularly strongly scented item, I’d keep it separate initially.

Don’t put it straight into the laundry basket alongside bedding, towels or children’s clothes, and don’t store it in a closed drawer with other fabrics while you’re trying to remove the fragrance.

Wash and air it separately until the smell has substantially diminished.

While fragrance molecules can move into the surrounding environment, I haven’t found sufficient independent evidence to say that intact fragrance microcapsules routinely transfer from one garment to another through ordinary household contact. The smell transferring and an intact capsule transferring are not necessarily the same thing.

We don’t need to claim more than we know.

Should you avoid fabric conditioner altogether?

Fabric conditioner is designed primarily to soften and condition fabrics, reduce static and make clothes feel smoother. Fragrance is an additional feature of many products rather than the sole reason fabric conditioner exists.

But if you’re trying to reduce persistent laundry fragrance, it’s worth looking carefully at the conditioner you’re using. Many modern fabric conditioners don’t just soften clothes; they are also formulated to leave fragrance behind, sometimes using fragrance technologies specifically designed to remain on fibres and release scent after washing.

That doesn’t mean you have to stop using fabric conditioner altogether. You might choose an unfragranced alternative, use it less frequently, or simply experiment with washing without it and see whether you actually miss it.

It’s also worth remembering that not every fabric necessarily needs conditioning after every wash. Towels, for example, can become less absorbent when fabric conditioner repeatedly coats the fibres, while some sportswear and technical fabrics specifically advise against its use.

If what you miss most when you stop using a fragranced conditioner is the smell rather than the softness, that’s an interesting thing to notice.

We’ve become very accustomed to fragrance being our signal that washing is fresh and clean. Fragrance-free laundry can initially seem as though something is missing simply because there isn’t a perfume announcing that it has been washed.

But clean and fragranced aren’t the same thing.

Clean doesn’t need to have a smell.

Sometimes we have to decide whether something is worth saving

This is perhaps the least satisfying answer, but it’s also part of conscious living.

I love second-hand children’s clothing. Passing things between families makes enormous environmental and financial sense.

But there have been occasions when I’ve washed something repeatedly, soaked it, aired it and tried to rescue it, and the fragrance has remained so persistent that I haven’t wanted it next to my children’s skin or bedding.

At some point, it’s reasonable to decide that an item isn’t working for your family.

A gentler approach to laundry

As with so much of lower-tox living, I don’t think this needs to become another list of things for parents to fear.

Once you understand that some modern laundry products have been deliberately engineered to leave fragrance behind, you can simply decide whether that’s something you want.

• Choose an unfragranced laundry detergent.
• Skip fragranced fabric conditioner and scent boosters.
• Keep heavily scented second-hand items separate initially.
• For robust fabrics, consider a warmer full wash if the care label allows it.
• Use plenty of rinse water.
• For stubborn fragrance, try a separate bicarbonate of soda or white vinegar soak.
• Give fabrics plenty of time and fresh air.
• Repeat rather than immediately reaching for increasingly aggressive treatments.

There doesn’t have to be fear behind any of this.

It’s simply choosing what you want your family’s clothes, towels and bedding to carry against their skin every day.
