5 Common Myths About Washing Activewear (and What to Do Instead)

Your activewear works hard—absorbing sweat, stretching through every squat, and keeping you comfortable during your toughest workouts. But if you’re washing it the wrong way, you could be cutting its lifespan in half or locking in stubborn odours.

The truth is, activewear needs special care to stay fresh, stretchy, and high-performing. Unfortunately, there are plenty of laundry myths that do more harm than good. Let’s bust the 5 biggest ones and show you how to keep your workout clothes looking (and smelling) brand new.

Myth 1: You Can Wash Activewear the Same Way as Regular Clothes

The Truth: Activewear fabrics like spandex and elastane are far more sensitive than cotton or denim. Throwing them in with heavy fabrics (like towels or jeans) can cause pilling, snags, and wear. Instead, wash activewear separately or in a delicates bag on a gentle cycle to protect the fibers and maintain stretch.

Myth 2: Fabric Softener Makes Workout Clothes Softer and Fresher

The Truth: Fabric softener leaves a waxy coating on moisture-wicking fabrics, which traps sweat, bacteria, and odour over time. If you want your gear to stay fresh and breathable, skip the softener altogether. A specialized detergent for activewear is your best friend here.

Myth 3: Hot Water is Best for Killing Bacteria and Odours

The Truth: While hot water is great for disinfecting towels and sheets, it’s too harsh for activewear. It can damage stretch fibers, fade colours, and even set stubborn odours deeper into the fabric. Cold water is the way to go—it’s gentler and works perfectly when paired with the right detergent.

Myth 4: More Detergent Means Cleaner Workout Gear

The Truth: Using extra detergent can backfire by leaving residue on performance fabrics. That residue holds onto sweat and odour, making clothes smell worse over time. Always use the recommended amount of detergent (or even slightly less) for activewear.

Myth 5: You Should Always Tumble Dry Activewear for Faster Drying

The Truth: High heat is the enemy of stretchy, high-performance fabrics—it breaks down elasticity and shortens the lifespan of your gear. Instead, air-dry your activewear whenever possible. If you’re in a rush, use a low or no-heat tumble setting.

Final Tips for Washing Activewear

• Turn your clothes inside out before washing to protect the outer fabric and target sweat buildup.

• Wash soon after workouts to prevent bacteria and odour from setting in.

• Use a detergent designed for activewear—they’re formulated to break down sweat and odour without damaging performance fabrics.

• Skip bleach and harsh chemicals, which weaken fibers over time.

Taking care of your activewear doesn’t have to be complicated—just ditch the myths and use the right techniques. Your leggings and sports bras will thank you with a longer lifespan, better stretch, and zero stink!
