How to Wash and Care for Elastane (Spandex) Clothing
To wash elastane, spandex, and Lycra (a branded fabric), there are a few things to know. These fibers give clothes their stretch and then return to their original state. Spandex blends are used in compression garments, sportswear, or any garment requiring comfort and a more conforming fit. Spandex is also used in swimsuits, hosiery, waistbands, and lingerie.
To maintain the elasticity of this fabric over time, always wash with cold water, inside a mesh garment bag and air-dry whenever possible. Wash any tight-fitting spandex garments after every use with mild detergent. Never use chlorine bleach. Here are the step-by-step instructions and helpful tips for care, repairs, storing, and more.
What is Elastane?
Elastane is a synthetic fiber manufactured from polyurethane that's more commonly referred to as spandex or by the brand name Lycra. It's mostly used in leggings, yoga pants, activewear, or shapewear.

Instructions

Presoak if Necessary
If the garment seems excessively stinky—like grimy workout clothes—give it a presoak in the sink in a solution of cool water and 1 cup baking soda for a minimum of 30 minutes or soak overnight before washing as usual.
-
Put Clothing in a Mesh Laundry Bag
Place the spandex clothing in a mesh laundry bag before adding it to the washing machine. A mesh bag helps protect the elastane fibers from becoming twisted and possibly snagging.
-
Set the Washing Machine
Set the washing machine’s settings so it runs on a gentle cycle and uses cold or cool water.
-
Air-Dry or Machine-Dry on Low
The heat of a clothes dryer can damage elastane fibers. If you have the time and space, hang the garments to drip-dry away from the sun or direct heat. Air-drying an item should take a few hours.
Treating Stains on Elastane (Spandex) Clothing
Treat oily stains on elastane garments as soon as possible because they can be difficult to remove once they set. Apply a small amount of mild liquid detergent to the stain, rubbing it in gently. Wash as instructed.
Elastane (Spandex) Care and Repairs
Spandex fibers are highly elastic, stretchable up to 500% without breaking, and can return to their original length after repeated stretching. They are durable, lightweight, and resistant to damage from body oils, sweat, and most chemicals found in deodorants and lotions. This being said, tears can still occur.
When mending by hand or machine, use a polyester thread because it has a bit of give. Keep stitches somewhat loose to allow for stretch. Avoid using straight pins on fabrics with a high percentage of spandex because they may leave tiny holes in the material. If using a machine to fix a tear, a ballpoint needle will reduce the possibility of snagging the fabric. Use a stretch stitch or a narrow zig-zag stitch, which is best for stretchy fabrics. As you're sewing, stretch the fabric as you guide it through the feed—but not too much, or it will pucker.
If you spot a snag, fix it with a needle and thread of the same color. Aim for the snagged thread with your needle. Poke the needle up through the fabric's wrong (opposite) side to the right side of the item. Grab the snag with the needle, and bring it back to the wrong side of the fabric to make it disappear. Sometimes, you can achieve this with just a needle and no thread.
Ironing Elastane (Spandex) Clothing
While spandex can be used alone to weave fabric, it's often combined with natural fibers like cotton and wool and other manufactured fibers, like polyester or nylon, to lend some stretch to these fabrics.
Even if the item is made of a blend, if the clothing is very high in spandex content, don't iron it—the heat will ruin the fibers. Luckily, spandex doesn't easily wrinkle. If it's a blend that doesn't contain a high amount of elastane, iron on the lowest setting. Keep the iron moving to avoid melting fibers.
Storing Elastane (Spandex) Clothing
Though elastane clothing is usually not considered delicate or keepsake quality, take care to clean it before you store it long-term, or else stains will become permanent. Store any clothing with spandex away from heat or light that may fade colors. Some Lycra blends, such as nylon, may fade over time if exposed to natural light in storage.
How Often to Wash Elastane (Spandex) Clothing
Elastane clothing is extremely durable when correctly washed. The fabric can withstand constant washing in cold water, so don't worry that you're washing it too much.
Tight-fitting spandex workout gear requires cleaning with every use, but you may be able to wear looser items two to three times before washing. Check the label to see the amount of elastane or spandex the garment contains before washing it. If it's 5 percent or less, you can wash and dry the item as usual. If it's higher, give it a little extra attention.
Tips for Washing Elastane (Spandex) Clothing
- Never use fabric softener or dryer sheets when washing spandex. Also, avoid products that combine detergent and fabric softener. The latter leaves a residue on spandex that can dull the finish and attract bacteria, which causes excessive odor.
- Avoid using chlorine bleach, which will destroy the elastane fibers. Instead, use oxygen bleach to brighten white clothing and remove stains.
- If you prefer, it's safe to take elastane clothing to the dry cleaners.
- Once in a while, you may want to tighten up form-fitting spandex clothing that's become slightly saggy, such as leggings. To do that, carefully toss the garment into a dryer on medium to high heat for no more than 30 minutes. This should be enough time to tighten the fibers without damaging the garment.
-
Is elastane or spandex machine washable?
Elastane or spandex is usually machine washable, but to be certain, check the fabric care label since it's often blended with other fibers. Wash in cold water with mild detergent on a gentle cycle.
-
Will elastane disintegrate in the dryer?
A full elastane garment, like a bathing suit, will lose its elasticity if repeatedly dried in a clothes dryer. Spandex does not do well in high heat; the fibers weaken and eventually break.
-
Will elastane or spandex lose its elasticity?
Even if you properly care for your elastane and spandex, the material will eventually lose some of its elasticity over time and a lot of use. You will speed up the process by introducing harsh chemicals like chlorine bleach, hot-temperature water, or a high-heat dryer.
