Should leggings go in the dryer?

Preferably not. Heat breaks down elastane, which is the fibre responsible for the garment returning to shape. If you use a dryer, use the lowest heat setting and take them out while slightly damp. Air drying flat is the single biggest thing you can do to extend their life.

How do I stop black leggings from fading?

Wash cold, inside out, with dark colours only, and avoid detergents with optical brighteners. Dry out of direct sunlight. Heat and surface abrasion cause most of the visible fading.

How do I remove pilling from leggings?

Use a fabric shaver held flat against the surface. Avoid razors, which cut into the knit and create thin spots. To prevent new pills, wash inside out in a mesh bag on cold and skip the dryer.

Can I restore stretched-out leggings?

A cold wash and air dry restores most temporary stretch, which is why they feel like new again after washing. If they stay loose after that, the elastane has permanently lost recovery. Hot water does not shrink them back; it accelerates the damage.

Care

Making stretch pants last

Key takeaways

The dryer is the main cause of permanently stretched-out leggings and waistbands.
Fabric softener coats elastane and reduces both stretch and moisture handling. Skip it.
Washing after every second or third wear is enough for jeans and jeggings; leggings worn for exercise need washing every time.
A stretched-out pair usually recovers in a cold wash and air dry. If it does not, the elastane is spent and no treatment restores it.

Washing

Cold water, always. Elastane degrades with heat. Cold also holds dark dye far longer, which is the other common complaint about black leggings.
Inside out. Reduces surface abrasion, which is what causes pilling and fading.
Gentle cycle, and a mesh bag for leggings. Zips and hooks from other garments do most of the visible damage.
No fabric softener. It leaves a coating that reduces stretch recovery and, on technical fabric, blocks moisture movement.
Mild detergent, less of it. Excess detergent does not rinse fully out of dense knits and stiffens them over time.

Drying

Air dry flat or on a rack. Hanging heavy wet knits by the waistband stretches the waistband, which is the part you least want stretched.

If you must use a dryer, use the lowest heat and remove the garment while it is still slightly damp. The last ten minutes of a hot cycle does most of the damage to elastane.

How often to wash

Leggings worn for exercise: every wear. Sweat degrades elastane and sets odour into synthetic fibres quickly.
Leggings worn as everyday wear: every two to three wears.
Jeggings and pull-on jeans: every three to four wears, or when they have stretched out enough to feel loose - a wash restores the shape.
Stretch jeans: every four to six wears. More frequent washing fades them without adding anything.

Fixing specific problems

Pilling between the thighs

Use a fabric shaver held flat against the fabric. Do not use a razor, which cuts into the knit and creates thin spots. Prevention is washing inside out, cold, in a mesh bag, and skipping the dryer.

Black leggings fading

Cold water and inside out are the two changes that matter. Wash dark garments together, avoid detergents containing optical brighteners, and keep them out of direct sun when drying.

Stretched-out leggings or waistband

A cold wash and air dry restores most temporary stretch. If they stay loose after that, the elastane has lost recovery permanently. Hot water does not shrink them back - it damages the remaining elastane and makes it worse.

Do jeggings shrink?

The cotton or rayon content can shrink slightly on first wash; the elastane does not. Wash cold and air dry and shrinkage is usually under 2%. A hot wash and hot dry can shrink the base fibre while damaging the elastane, which produces a garment that is both tighter and baggier in different places.

Storage

Fold knits rather than hanging them. Hanging leggings and ponte pants by the waistband over months lets gravity stretch the band. For woven jeans, hanging is fine and helps them keep their line.
