Sweat, high-intensity workouts, and frequent washing: your training gear goes through a lot. To ensure your kit supports your performance long-term while maintaining its technical properties and comfort, proper care is essential. This guide reveals the best tips for maintaining your sports equipment and boosting its lifespan.
Why proper care matters for your activewear
Performance wear is engineered from specific technical fibres, such as polyester or elastane, often combined with breathable and anti-odour treatments. These materials perform best thanks to fine, sensitive structures that can be damaged by high temperatures or aggressive cleaning products. Incorrect care clogs the fibres, reduces moisture-wicking capabilities, and diminishes comfort during exercise.
Poor washing habits also encourage detergent build-up and bacterial growth, leading to persistent “gym smells”. Over time, textiles lose their elasticity, wear out prematurely, and begin to pill—significantly shortening the life of gear that was built to last.
Before you start the wash
Sort by colour and fabric type
Separate your clothes by colour and composition. Synthetic textiles require different care than cotton-polyester blends. Group dark colours together, isolate whites, and wash brightly coloured pieces separately to avoid dye transfer. This preventive step ensures you can match the wash cycle to each fibre’s specific needs.
Empty pockets, zip up, and turn inside out
Always check your pockets; a forgotten tissue can cover your entire load in white lint. Close all zips to prevent them from snagging other garments and turn printed or brightly coloured items inside out to protect the designs. This also preserves seams and reduces visible wear on high-friction areas.
Pre-treat stubborn stains
For ingrained stains, stick to gentle solutions. Bicarbonate of soda mixed with a little water creates an effective paste for sweat marks. Rubbing a bit of traditional Marseille soap (or a gentle laundry bar) onto the area before washing will tackle most grime. Avoid harsh chemical stain removers that could strip the technical coatings from your clothes.
The machine wash
Choose the right temperature
The golden rule: 30°C maximum for most technical fabrics. This temperature is enough to eliminate odour-causing bacteria while protecting the integrity of the fibres. For particularly dirty whites, 40°C is the absolute limit. Hot water degrades elastomers, shrinks fibres, and destroys surface treatments—meaning your running leggings will lose their compression and your gym top will stop wicking sweat.
Select the ideal cycle
Use the “Synthetics” or “Sportswear” programme if your machine has one. These cycles adjust the wash time, spin speed, and drum movement to suit technical textiles. A “Delicate” programme is also suitable, as the reduced spin cycle is gentler on elastic fibres. Avoid long, intensive cycles that cause unnecessary wear and tear.
The perfect detergent
Opt for a liquid detergent specifically formulated for technical fabrics or colours. These formulas respect synthetic fibres and preserve surface treatments. Use it sparingly: too much product leaves a residue that builds up in the fibres and encourages bacteria. The recommended dose for a normal load is more than enough.
Ban fabric softener and bleach
Fabric softener is the ultimate trap for gym wear. It leaves a waxy film that blocks the micro-pores of technical fibres, cancelling out their breathability. Your clothes effectively become “waterproof” to air, trapping moisture against your skin. Bleach is equally harmful, weakening synthetic fibres and causing irreversible discolouration. Both should be permanently removed from your sports laundry routine.
Don’t overload the drum
Leave plenty of space. Clothes need to move freely to be properly cleaned and rinsed. An overloaded machine results in a poor wash, insufficient rinsing, and more creases. Fill the drum to a maximum of two-thirds to ensure optimal circulation of water and detergent.
Drying: Crucial for durability
Air dry in the shade
Natural drying is the safest method. Hang your clothes on a drying rack in a well-ventilated area, away from direct sunlight. UV rays can fade fabrics and weaken certain synthetic fibres. Reshape your garments while they are damp to prevent permanent creases and maintain their original fit.
Avoid the tumble dryer
The tumble dryer is the enemy of technical textiles. Intense heat shrinks fibres, destroys elasticity, and can even melt certain synthetic components. Once damaged, technical properties are gone for good. If you absolutely must use one, select a “Cool” or “Air” setting with no heat, and remove the items while they are still slightly damp.
Tips for fast, effective drying
To speed up natural drying, gently roll your clothes in a clean towel to squeeze out excess moisture before hanging. Place your drying rack near a source of ventilation—such as an open window or a fan—to accelerate evaporation while preserving the fabric’s structure.
Post-workout habits to save your kit
Don’t let wet gear linger
The fundamental rule: never leave sweat-dampened clothes in a closed gym bag. This creates a breeding ground for bacteria and mildew. Take your gear out as soon as you get home to prevent stubborn odours and maintain hygiene.
Air out immediately
Hang your clothes in a ventilated spot as soon as you return. Even if you don’t plan to wash them until later, this prevents bacteria from settling in and makes it easier to remove smells during the wash. For lightly used gear, a good airing might even refresh it for one more quick session.
Mistakes to avoid at all costs
- Leaving laundry too long: Delaying the wash allows stains and odours to set. Aim to wash your gear within 24 to 48 hours.
- Using harsh chemicals: Powerful stain removers and bleach destroy the technical properties of your clothes.
- Ignoring care labels: Every technical garment has specific needs. The care label is your reference for max temperatures and specific “dos and don’ts.”
FAQ – Caring for your sportswear
Can I wash my trainers in the machine?
Some trainers can handle it if you remove the laces and insoles, use a laundry bag, and select a delicate 30°C cycle. Always air dry them away from direct heat. Check the manufacturer’s guidelines first.
How do I get rid of persistent smells?
For stubborn odours, soak your clothes in a mix of lukewarm water and bicarbonate of soda for an hour before washing. You can also add a splash of white vinegar to the fabric softener drawer to neutralise bacteria.
How often should I wash my gym clothes?
Wash them after every intense session or as soon as an odour appears. For low-impact activity without much sweat, an item can be worn 2-3 times if aired out well. Just don’t let damp textiles sit at the bottom of a bag.
Does compression gear need special care?
Yes. Compression wear is very sensitive to heat. Wash in cold water or 30°C max, without softener, and use a gentle spin. Dry flat away from radiators or tumble dryers to preserve the elasticity.
