Compression leggings rely on stretch fibers and snug elastic recovery to support your legs and stay in place. Washing them incorrectly can weaken that recovery, loosen the waistband, fade dark fabric, trap detergent against your skin, or create permanent creases. High heat is especially risky: a hot washer or dryer can damage elastane, even when the leggings still look fine after one wash.
The safest routine is simple: follow the care label first, use cold water, choose a gentle detergent, avoid fabric softener and bleach, and let the leggings air-dry. These instructions work for most plus size compression leggings, including pocketed yoga and workout styles. They also apply whether you paid about $8 to $14 for a basic pair, such as the SINOPHANT High Waisted Leggings with Pockets, Full Black, XXL at $8.49, or the MEJING Plus Size Capri Leggings Women Pocket Yoga Pants Tummy Control Black at $13.99.

Quick answer: Our top pick in 2026 is the Cold water, about 60–80°F — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
What You Need
| Item | Why | Optional? |
|---|---|---|
| Cold water, about 60–80°F | Helps protect elastic fibers, dark dyes, and printed details. | No |
| Gentle liquid detergent | Dissolves easily and removes sweat without leaving as much residue as powder. | No |
| Mesh laundry bag, about 12 by 16 inches | Reduces snagging, stretching, and contact with zippers or hook-and-loop fasteners. | Yes, but recommended |
| Clean towel | Helps press out excess water without twisting the fabric. | Yes |
| Drying rack or wide hanger | Allows air circulation while reducing stress on the waistband. | Yes |
| Soft toothbrush or cloth | Useful for gently treating deodorant, mud, or a small stain before washing. | Yes |
Use approximately 1 teaspoon of concentrated detergent for one or two pairs, or follow the bottle’s low-load measurement. More soap does not mean cleaner leggings; excess detergent can leave a sticky film that holds odor and irritates skin. Do not use fabric softener, chlorine bleach, dryer sheets, or stain removers containing strong solvents.
Step-by-Step
1. Read the care label and empty the pockets (2 minutes)
Look for the manufacturer’s instructions inside the waistband or along a side seam. If the label says hand-wash only, do not put the leggings in a machine. Also check whether the garment includes a compression panel, reflective print, silicone grip, or bonded seam that requires special care.
Turn out every pocket. Remove tissues, cards, keys, and earbuds. A forgotten item can stain the fabric or pull a pocket out of shape. Close zippers and fasten any hook-and-loop closures on other garments that will share the load.
2. Pre-treat visible marks (3–5 minutes)
Rinse sweat, mud, or food stains with cool water from the back of the fabric. Apply a drop of gentle liquid detergent to the mark and lightly pat it with your fingers or a soft cloth. For dried mud, let the spot soften for a few minutes first; rubbing aggressively can create a shiny patch or pill the surface.
Skip soaking in undiluted detergent. If the leggings contain bright colors, test any specialty stain product on an inconspicuous inside seam and follow the care label.
3. Turn the leggings inside out (1 minute)
Turning the garment inside out protects the outer finish, printed logos, and color from friction. It also puts the side that contacts sweat closest to the detergent and water. Gently straighten the legs and waistband rather than pulling them to their full stretch.
4. Choose hand-washing or a gentle machine cycle (5–30 minutes)
For the longest possible garment life, hand-wash the leggings in a clean sink or basin filled with cool water. Add the measured detergent, submerge the leggings, and gently move them through the water for about 2 minutes. Let them sit for another 5 minutes, then rinse until the water runs clear.
For machine washing, place one or two pairs in a mesh bag. Wash with other lightweight activewear, not towels, denim, bras with hooks, or garments with rough zippers. Select the delicate, hand-wash, or activewear cycle and use cold water. A low-spin setting is preferable because fast spinning can stretch the waistband and seams.
Do not pack the washer tightly. Clothing should fill no more than about two-thirds of the drum so water and detergent can circulate. A full load can trap odor and increase rubbing between garments.
5. Rinse thoroughly (2–5 minutes)
Detergent residue is a common cause of stiffness, itching, and lingering odor. If washing by hand, rinse in fresh cool water at least twice. Press the leggings gently under the water instead of twisting them. In a machine, use an extra-rinse option if the fabric feels slick or smells strongly of soap after the cycle.
6. Remove water without wringing (2 minutes)
Lift the leggings with both hands so the wet fabric does not hang from one narrow point. Press them against the side of the sink or washer. For hand-washed leggings, lay them flat on a clean towel, roll the towel loosely, and press along the roll. Unroll and repeat with a dry section if necessary.
Never wring, twist, or pull the legs apart. Wet elastane is more vulnerable to stretching, and aggressive handling can leave the garment permanently less supportive.
7. Air-dry completely (4–24 hours)
Lay the leggings flat on a drying rack, or drape them over two or more bars so the weight is distributed. You can also hang them from the gusset with a wide, smooth hanger, but avoid narrow clips that leave dents. Keep them out of direct, intense sunlight and at least 3 feet from radiators, heaters, and hot air vents.
Do not use a tumble dryer unless the label specifically permits it. If machine drying is allowed, select the lowest heat for the shortest time and remove the leggings while they are still slightly damp. Never iron compression leggings; heat from an iron can flatten texture and harm elastic fibers.
Mistakes to Avoid
- Using hot water: Temperatures above about 100°F can accelerate elastic breakdown. Cold water is the safer default.
- Adding fabric softener: It coats performance fibers and can reduce moisture-wicking ability while trapping body oils.
- Using too much detergent: Start with about 1 teaspoon for a small load and increase only if the label requires it.
- Washing with rough items: Towels, denim, and garments with metal hardware can cause pilling and snags.
- Leaving damp leggings in the washer: Move them to the drying rack within 30 minutes after the cycle ends to limit mildew odor.
- Stretching them on a hanger: A wet waistband hanging from one point can lose its shape.
- Using bleach on black fabric: It can weaken fibers and create orange or pale spots.
- Ignoring an odor after washing: Rewashing repeatedly with more detergent often makes residue worse. Use less detergent and improve rinsing instead.
How Often
Wash compression leggings after every workout, run, long shift, or day when you perspired noticeably. Sweat, skin oils, sunscreen, and body lotion can build up inside the fabric and affect odor and comfort. If you wore them briefly for light activity and they stayed dry, air them out fully before wearing them again; avoid wearing the same pair more than twice without washing.
Rotate at least two or three pairs when possible. This gives each pair 24 hours or more to dry completely and reduces repeated stress on one waistband. Inspect pockets and seams after each wash, particularly on plus size styles with wide tummy-control panels or heavy pocket stitching.
When to Call a Pro or Replace
Most washable compression leggings do not need professional cleaning. Consult a tailor or the manufacturer when a seam has opened, a pocket is pulling away, or a waistband needs repair. Do not attempt to sew through a compression panel if the repair could create a hard ridge against your skin.
Replace the leggings when they no longer provide their intended support, remain loose after washing, have thinning or transparent areas, show widespread pilling, or develop stretched seams that cannot lie flat. Also replace them if the elastic has become brittle, sticky, or cracked. If you wear compression garments for a diagnosed medical condition, ask your clinician how much support you need before substituting a worn-out pair with a casual athletic legging.
FAQ
Can I wash plus size compression leggings in a washing machine?
Usually, yes, if the care label permits machine washing. Turn them inside out, place them in a mesh bag, use cold water, choose a delicate or activewear cycle, and use a low-spin setting. Wash with lightweight clothing rather than towels or denim.
Why do my compression leggings still smell after washing?
Odor often comes from detergent buildup, insufficient rinsing, or leaving damp leggings in the washer. Use less detergent, add an extra rinse, and air-dry promptly. Avoid fabric softener, which can trap oils and odor inside performance fibers.
Can I put compression leggings in the dryer?
Air-drying is the safest choice. Use a dryer only when the care label allows it, and select the lowest heat. Remove the leggings while slightly damp. High heat can reduce elasticity and shorten the garment’s useful life.
Should I wash black compression leggings separately?
Wash new black leggings with dark, lightweight items for the first few cycles because some dye transfer is possible. After that, they can usually be washed with other dark colors. Keep them away from lint-producing towels and pale garments.
