How to Remove Smell from Hoodies and Sweatshirts

The hoodie is the most-worn, least-washed item most people own — which is exactly why it develops that distinctive smell. Here's how to keep hoodies and sweatshirts fresh between washes.

Be honest about your hoodie. It's the thing you reach for most days, wear for hours, sleep in, throw on over everything — and wash maybe once a fortnight, if that. No other garment gets that ratio of constant wear to rare washing, which is exactly why the well-loved hoodie develops its own distinctive, slightly funky smell over time. The fix isn't washing it to death; it's freshening it the way its wear pattern actually demands.

Here's how to keep hoodies and sweatshirts fresh between the washes they don't get often enough.

Why hoodies smell the way they do

Hoodies combine every odor-trapping factor. They're thick — usually a cotton-polyester fleece — so they hold sweat and oils deep in a dense, lofted fabric. They're worn for long stretches, often in varying temperatures (cool outside, warm indoors), so you sweat into them more than you realise. And they're washed rarely because they feel like outerwear, so the build-up accumulates over many wears.

The polyester content is part of why the smell gets stubborn — it holds sweat oils the way synthetics trap odor worse than cotton, while the cotton portion absorbs sweat readily. The hood and collar, sitting against your neck and hair, and the cuffs and underarms take the worst of it.

Why over-washing isn't the answer

You could just wash your hoodie constantly, but thick fleece takes ages to dry (especially in humidity), frequent washing pills and flattens the fabric, and drawstrings and prints don't love repeated cycles. A hoodie washed every few wears wears out and loses its softness fast — and still smells again within a couple of wears because the deep odor in the blend isn't fully flushed.

The better approach matches the garment's reality: freshen often, wash occasionally. That keeps the hoodie soft, intact and fresh without the constant laundry.

Freshening hoodies between wears

After wearing, turn the hoodie inside out and hang it in moving air rather than balling it up on a chair or in a bag — trapped warmth and moisture in thick fleece is a fast route to smell. Give it a few hours. Then mist the hood, collar, cuffs and underarms with ODORSTRIKE and let it dry.

It neutralises the sweat odor built up in the fabric rather than masking it, so the hoodie genuinely freshens up instead of smelling of fragrance over funk. Because it dries clear and residue-free, it's safe on dark hoodies and prints alike — and it reaches the deep odor in the blend that airing alone can't.

The drawstring, pocket and sleep factor

Hoodies hold smell in spots people never treat. The drawstring sits against your neck and soaks up sweat and hair oil; the kangaroo pocket traps hand sweat, crumbs and warmth; and if you sleep in a hoodie, it picks up a full night of body moisture on top of the day's wear. Spraying only the body misses all three.

When you freshen a hoodie, hit the drawstring, the inside of the pocket and the cuffs along with the hood and underarms — these are the quiet sources of the worn-hoodie smell. And if it's a sleep-and-lounge hoodie rather than an outdoor one, treat it more like daily wear: air it every morning and freshen it more often, because it's accumulating moisture around the clock rather than just when you're out.

Washing hoodies the right way

When a hoodie does need a wash — genuine build-up that won't freshen out, a spill, visible soil — turn it inside out, use cold water and a gentle cycle, skip fabric softener (it coats the fleece and locks odor in over time), and dry it thoroughly. Thick fleece that's put away even slightly damp turns musty fast, so make sure it's bone-dry, ideally with airflow or sun.

With freshening handling the everyday, you'll find a hoodie needs far fewer washes — which keeps it soft and lasting while staying fresh.

The hoodie routine

Simple and repeatable: wear it (a lot), air it inside out, freshen the hood, collar, cuffs and underarms, and wash only when it genuinely needs it. That keeps your most-worn garment fresh without the constant washing that wears it out — and without ever being the person whose hoodie announces how many times it's been worn.

A hoodie is meant to be lived in. A little airing and a 50ml bottle of ODORSTRIKE let you live in it and keep it fresh, which is the whole point. It's the same neutralise-and-rewear approach that works across your whole wardrobe.
