How to Wash Activewear So It Lasts Longer

What is the best way to wash activewear?

Most activewear is made from synthetic fibers such as nylon or polyester blended with spandex. These fabrics do best with a gentle routine: cool water, mild detergent, low agitation and no high heat. The aim is to protect the stretch fibers that let the fabric spring back, and the surface finish that gives it its look and feel.

Start with the care tag sewn into the garment. It is written for that exact fabric and trim, so it takes priority over any general advice, including this guide.

• Turn items inside out to protect the outer surface and any texture.
• Close zips and fasten hooks so they do not snag other pieces.
• Wash in cold water on a gentle or delicate cycle.
• Use a small amount of mild liquid detergent.
• Leave out fabric softener and bleach.
• Air dry flat or on a hanger, out of direct heat.

Why wash activewear in cold water and inside out?

Heat is the main enemy of spandex. Hot water and high dryer heat can weaken stretch fibers over time, so waistbands and seats lose their spring and the fabric can start to look thinner when stretched. Cold water is gentler and works well with modern detergents for everyday sweat and grime.

Washing inside out means the inside of the garment, which touches your skin, gets the most contact with water and detergent, while the outside is protected from rubbing against other items. That helps reduce pilling and keeps brushed, ribbed and seamless textures looking fresh. A mesh laundry bag adds extra protection for bras and delicate pieces.

Should I use fabric softener on leggings and sports bras?

No. Fabric softener works by leaving a thin coating on fibers. On stretch synthetics, that coating can build up, make the fabric feel slick or heavy, and affect how well it handles moisture. It can also trap residue that makes clothes feel less fresh after washing.

If you want a softer feel, use a little less detergent and make sure it rinses out fully. An extra rinse cycle can help. Avoid bleach as well, since it can damage spandex and fade colors.

Can I put activewear in the dryer?

Air drying is the safest option. Lay pieces flat on a rack or hang them over a line, out of direct sunlight and away from radiators or heaters. Most thin synthetic activewear dries fairly quickly this way.

If you must use a dryer, choose the lowest heat or an air-only setting and take items out while they are still slightly damp. Avoid high heat completely, as it is the most common cause of tired waistbands and lost stretch. Never iron stretch fabrics on a high setting, and avoid ironing seamless pieces altogether.

What should I keep activewear away from in the wash?

Rough and hooked items cause most snags and pilling. Wash activewear with similar lightweight items, or in a mesh bag, rather than with jeans, towels or anything with Velcro.

• Velcro and hook-and-loop fasteners, which grab and pull fibers.
• Open zips, hooks and buckles, which can snag the knit.
• Towels and fleece, which shed lint that clings to synthetic fabric.
• Heavy denim, which rubs and can transfer dye.
• New bright or dark colors, which are best washed separately the first few times.

How do I wash swimwear?

Swimwear needs a little extra care because chlorine, salt water, sand and sunscreen are all hard on stretch fabrics. Rinse your swimsuit in cool fresh water as soon as you can after every wear, even if you only sunbathed.

Then hand wash it in cool water with a small amount of mild detergent, gently squeeze out the water without wringing or twisting, and lay it flat to dry in the shade. Avoid the dryer, and do not leave a wet swimsuit rolled up in a towel or bag for long. If a bikini or one-piece has removable pads, take them out to wash and dry them separately so they keep their shape. Rotating between two swimsuits gives each one time to dry fully.
