How to Get Rid of Sweat Smell in Workout Clothes

The leggings look clean. The top feels fine. But the moment you start to move—there it is again. That stubborn, sour note of sweat clinging to your favourite gym kit. Ordinary detergents often mask the problem with fragrance, only for the smell to return the moment heat and sweat hit the fabric. It’s one of the most frustrating issues for anyone who trains hard. You want clothes that feel fresh, not ones that betray you halfway through a session. So how do you get sweat smell out of clothes for good? Let’s break it down.
Why Workout Clothes Hold Onto Odour
Synthetic fabrics polyester, nylon, elastane—are engineered for performance. They stretch, wick sweat, and dry fast. But there’s a hidden trade-off: those same fibres trap odour-causing bacteria deep in their structure. Once sweat and body oils settle into the fibres, they create the infamous “permastink.” Regular detergents wash the surface but can’t reach deep enough to neutralise bacteria. That’s why odours resurface as soon as you warm up again. This is where a proper sweat smell remover is needed—not just something that masks the problem.
What is the Best Odour Eliminator for Fabric?
Most laundry products try to hide the smell. A shot of fragrance here, a brightener there. But BIORESTORE Odour Defense was designed to work differently. It’s more than just a cloth smell remover—it’s a science-backed treatment that tackles the root cause of odour.
Here’s how it works:
- Coconut-derived active: A sustainable ingredient that helps break down sweat residues.
- Self-Renewing Si-QAC™ Odour Barrier Technology: This bonds directly to fibres, creating a shield of positively charged “spikes.” These spikes attract, rupture, and neutralise odour-causing bacteria.
- Lasting effect: The barrier doesn’t rinse away it stays active for up to 10 washes.
The result? True sweat odour removal for activewear, not a cover-up. You get fresher kit that actually resists future smells.
How Do You Get Armpit Smell Out of Clothes?
Armpit odour is the trickiest of all. It’s not just sweat; it’s sweat mixed with deodorant and bacteria, creating that stubborn patch under your tops. Traditional detergents struggle here, but Odour Defense makes it simple:
- Pick the problem pieces — gym tops, sports bras, or uniforms that smell worst.
- Drop in a sachet — pre-dosed, no guesswork. Each treats around 1kg of clothing.
- Wash warm — 40°C for at least an hour gives the treatment time to work.
- Tumble dry if you can — heat helps lock in the barrier.
After one wash, the armpit smell is gone. And because the barrier is bonded to fibres, the smell doesn’t rush back after your next training session.
This is what sets Odour Defense apart as a sweat smell remover: it fixes today’s odour and prevents tomorrow’s.
Everyday Habits to Boost Sweat Odour Removal
Even with the best odour technology, small tweaks in your laundry routine can help:
- Air before washing: Don’t leave sweaty kit bunched up in a bag. Letting it dry stops bacteria from multiplying.
- Skip the softener: Fabric softeners coat fibres, making odour harder to remove.
- Wash inside out: This exposes the sweat-heavy areas to water and treatment.
- Don’t overload the drum: More space means better penetration of odour removers.
Some people reach for vinegar or baking soda as a cloth smell remover. While these can freshen clothing in the short term, they don’t provide the long-lasting protection that keeps sweat smell out of clothes after multiple wears.
Why Odour Defense is Different
BIORESTORE Odour Defense isn’t just another detergent. It’s part of a new generation of Laundry Re-Tergent™ Treatments—precision products that focus on fabric care, not just stain removal.
Here’s why it matters for activewear:
- Neutralises odour at the source instead of covering it up.
- Prevents permastink, saving your favourite leggings and tops from early retirement.
- Gentle on fibres, keeping your kit stretchy and strong.
- Eco-conscious, reducing the need for rewashing and wasted water.
For anyone who trains regularly, this means you don’t need to replace your gear as often. Fewer rewashes, fewer discarded leggings, and a smaller environmental footprint.
That’s not just sweat odour removal for activewear—that’s sustainable garment care.
The Human Side of Freshness
Think about it. Clothes aren’t just fabric—they carry our routines, our pride, our energy. Pulling on a favourite running top should feel like motivation, not a compromise.
When your kit smells fresh, you feel fresh. Confidence builds. You run harder, lift heavier, push further. That’s the subtle power of a sweat smell remover that actually works—it doesn’t just clean clothes, it resets how you feel in them.
