You've washed your Activewear or gym kit. It smells like it's clean coming out of the washing machine. You put it on for your next gym session and within ten minutes... there it is. That awful smell. The one that makes you self-conscious mid-deadlift.
Sound familiar? You're not imagining it, and it's definitely not because you're "extra sweaty." It's a laundry problem - and it's incredibly common with activewear.
Here's what's actually going on, and how to fix it for good.
Why Activewear Holds Onto Sweat Smell
Modern activewear is engineered to perform and handle how hard you might train. It's often tight made with moisture-wicking synthetic fibres like polyester, nylon, and spandex which are brilliant at pulling sweat away from your skin however that same tightly woven weave traps bacteria, body oils, and odour deep inside the fabric where regular detergents simply don't reach.
Add to that the fact that most generic laundry detergents leave a residue on synthetic fibres (yes, even after rinsing), and you've essentially created a warm, cosy home for odour-causing bacteria to set up camp. Every wash makes it worse, not better.
The Fabric Softener Trap
If you're using fabric softener on your activewear or gym gear, stop. Right now. Fabric softener coats fibres with a waxy layer that locks in bacteria and blocks the fabric's moisture-wicking ability. It makes your gym kit feel soft initially but it's only masking the odour not removing it and that smell will come back and get even worse over time. It's one of the most common mistakes when it comes to washing your activewear, sports clothes or work out gear.
How to Actually Get Sweat Smell Out of Activewear
Here's the method that works:
- Don't let it sit. Leaving sweaty gym clothes in a bag or hamper for hours (or days, no judgement - life gets busy!) lets bacteria multiply. Air them out or better still wash them as soon as possible after your session.
- Turn clothes inside out. The inside of your activewear is where the bacteria lives. Turning it inside out means the wash water and detergent hit where it matters most.
- Use cold water. Hot water can set odours and damage technical fabrics. Cold water is kinder to the fabric and properly effective when you're using the right detergent.
- Use a detergent designed for activewear. This is the non-negotiable. A standard generic laundry detergent is often not formulated for tight synthetic weaves of performance fabrics. You need something that can genuinely deeply clean and better still has naturally antibacterial action to penetrate into the fibre, help fight bacteria while not leaving residue.
- Skip the dryer. If you can, air dry where ever possible. Heat degrades elastic fibres and can bake in any remaining odour or stains.
The Right Detergent Makes All the Difference
Active Savvy Sports & Activewear Wash was specifically formulated for this exact problem. It's an Australian-made naturally antibacterial laundry sanitiser and specifically curated sports & activewear detergent wash in one - its designed to specifically for those technical fabrics and synthetic fibres, will work to neutralise odours at the source (not just mask them), and rinses completely clean without leaving residue.
One 500ml bottle gives you up to 65 washes. It's 100% biodegradable, free from synthetic fragrances, is ideal for all activewear fabrics including compression wear, yoga pants, and technical running gear etc.
Activewear is concentrated and you generally only need to use a little bit however, if your activewear or gym kit has built up serious odour over time, try soaking it in a solution of Active Savvy and cold water for 30 minutes before washing. It works.
The Bottom Line
Getting sweat smell out of activewear isn't about washing more (or using a lot of the wrong detergent) it's about washing smarter. The right technique combined with a detergent that's actually built for the job makes all the difference. Your activewear or gym kit will thank you. So will everyone around you at the gym!
