Rinse a scrunch bikini right after wearing it, hand-wash in cold water with a mild, enzyme-free detergent, skip the wringing, and lay it flat to dry out of direct sun. This sequence protects the ruching, the color, and the stretch of the elastane underneath.
TL;DR:
- Hand-washing in cold water with a neutral, enzyme-free detergent extends the life of elastane and preserves the ruching and color.
- Using a mesh bag on gentle, cold machine cycles is acceptable but carries some risk of elastic wear compared to hand-washing.
- Laying suits flat to dry in the shade prevents elastic stretching and color fading, while hanging or drying in direct sun accelerates damage.
- Rotating multiple suits and storing them loosely reduces elastic strain and maintains shape over a season.
- Choosing fabrics with higher nylon or polyester ratios and avoiding harsh detergents or bleach improves long-term durability.

Quick care checklist for every wear
A scrunch bikini holds its shape through routine, not luck. The ruching depends on elastic threads that weaken with heat, chlorine, and rough handling, so a short routine after each swim pays off over a full season.
- Rinse in plain water right after swimming to flush out chlorine, salt, and sunscreen residue.
- Shake off excess water and blot with a towel. Never wring the fabric; twisting stresses the ruched seams.
- Hand-wash as soon as practical using a small amount of mild detergent.
- Roll the suit in a dry towel to pull out extra moisture, then lay it flat to dry.
- Rotate between two or more suits and store them loosely so elastic fibers get recovery time.
Pro Tip: Keep a travel-size bottle of mild liquid detergent in your beach bag so you can hand-wash within an hour of leaving the pool or ocean.
How to hand-wash a scrunch bikini step by step
Cold water matters more than most people realize. Laundry experts recommend rinsing swimsuits after use and hand-washing in cold water with a mild, neutral-pH liquid detergent, since warm or hot water loosens the bonds in elastane and speeds up color fading. Spandex and Lycra respond the same way: cold water washing with gentle handling helps these fibers hold their elasticity over time.
Follow these steps for a scrunch bikini specifically, since the gathered seams need lighter handling than flat fabric.
- Fill a sink or basin with cold water, ideally under 85°F.
- Add a small amount of enzyme-free, neutral-pH liquid detergent and mix it into the water before adding the suit.
- Submerge the bikini and let it soak for up to 10 minutes.
- Gently swish the fabric with your hands. Avoid scrubbing the ruched areas, since friction can pull at the elastic casing.
- Press gently along the gathered seams to loosen any trapped sunscreen or oil, but don’t stretch or pull.
- Drain the basin and refill with clean cold water, then rinse until the water runs clear.
- Lift the suit out with two hands spread under the fabric rather than pinching one spot, which keeps the ruching from distorting.
This approach keeps both the stretch and the ruched detail intact longer than any shortcut. For a longer walk-through of the brand’s own process, see this step-by-step bikini care guide.
When machine washing is okay, and when it isn’t
Hand-washing is the safer default, but using a mesh bag on the washer’s gentle, cold cycle is an acceptable fallback when hand-washing isn’t possible, even though it still carries some risk of mechanical wear on elastic and trim.
- Place the bikini inside a zippered mesh bag before adding it to the wash.
- Use the gentle or delicate cycle with cold water only.
- Add a small amount of liquid detergent. Skip powder detergents, bleach, and fabric softeners, since they can break down tight weaves and elastane fibers.
- Pull the suit out the moment the cycle ends. Letting it sit damp invites mildew and fades color faster.
- Never put a scrunch bikini in the dryer. Heat from dryers destroys stretch fibers and permanently damages fiber memory.
Skip the washer altogether for suits with delicate trims, metal rings, beading, or sewn-in ruching that relies on a single stitched channel. Those details are easier to damage in a machine than by hand.
Drying and storing a scrunch bikini without ruining it
Water trapped in a scrunch bikini’s folds adds weight that pulls on the ruching, so getting it out gently matters as much as the wash itself. Roll the suit in a dry towel and press, don’t twist, to draw out moisture. Then lay it flat on a clean towel in the shade, away from direct sun.
Hanging a wet scrunch bikini seems convenient, but gravity stretches the wet elastane at the shoulder straps or waistband, and that stretch doesn’t always bounce back. Experts recommend laying suits flat to dry, since heat and UV exposure accelerate elastane breakdown and color fading. Skip the dryer, skip the iron, and skip steaming over direct heat sources for the same reason.
Storage between wears matters too:
- Fold loosely or lay flat rather than cramming the suit into a tight ball, which creases the ruched gathers.
- Use a breathable bag or drawer rather than sealed plastic, which traps moisture and odor.
- Rotate suits by season so no single piece carries the full weight of a summer’s wear.

How fabric choice shapes the care a scrunch bikini needs
Most scrunch bikinis use a blend of nylon or polyester with elastane, and the ratio changes how the suit behaves in water and sun. Nylon blends tend to feel softer and dry a bit slower, while polyester blends often resist chlorine fading better but can feel stiffer against ruched seams.
- Nylon and elastane blends: softer hand, good stretch recovery, but more sensitive to chlorine over time.
- Polyester and elastane blends: firmer structure, often holds shape well, but can feel less forgiving in a scrunch design.
- Tightly woven fabrics: high-end swimsuits with tightly woven nylon and elastane blends are more durable when cared for gently, and fabric composition is the largest single factor in longevity.
Chlorine-resistant fabric matters more than most buyers expect. Chlorine-resistant fabrics are often nylon or polyester blends with added treatments that help maintain color and shape under repeated pool exposure, which is worth checking if you swim laps often rather than only lounging at the beach.
Check the care label and fabric content before buying so expectations match the suit’s actual materials. A quick primer on common swimwear fabrics is available in this guide to smart fabric choices.
Removing sunscreen, oil, and chlorine stains
Sunscreen is usually the toughest stain on a scrunch bikini because the oils bind to synthetic fibers and the ruched folds trap residue. Frequent exposure to sunscreen, oils, salt, and chlorine accelerates wear, and prompt rinsing plus careful cleaning reduces that chemical damage.
- Apply a small amount of gentle dish soap or an enzyme-free prewash directly to the stained area.
- Work it in lightly with your fingers, focusing on the stain rather than the whole garment.
- Let it sit for a few minutes, then rinse with cold water.
- Repeat once if the mark hasn’t lifted. Avoid bleach or harsh solvents, which weaken elastane and can discolor the fabric.
- Spot-test any treatment on an interior seam first to confirm it won’t affect the color.
- Rewash the full suit using the cold water hand-wash method once the stain is gone.
For stubborn or set-in marks, professional cleaning may be worth considering rather than repeated at-home treatments that risk further damage. Letting sunscreen absorb fully into skin before swimming and rinsing promptly afterward prevents most stains before they start. A fuller walkthrough by stain type is in this guide to treating sunscreen stains on swimwear.
Keeping the scrunch looking sharp over time
The ruched look comes from elastic thread stitched into a casing that gathers the fabric. That casing is a stress point, so pulling the suit on and off by the straps instead of the waistband helps it last.
- Reshape the gathers by hand while the suit is still damp, smoothing the folds into their original pattern.
- A light steam from a distance can relax stubborn creases, but never steam a wetsuit or hold the steamer close to elastic seams.
- If the elastic inside the casing feels loose or the ruching has gone flat, that’s usually a sign the elastic needs replacing rather than just reshaping.
- For loose threads or a casing that’s started to pull apart, a quick stitch repair is simpler than letting it run.
Pro Tip: Fasten any ties or straps before washing so the ruching doesn’t shift or bunch unevenly in the water.

Simple repairs that extend a scrunch bikini’s life
Most scrunch bikini problems come down to two things: tired elastic or a loosened seam, and both are fixable at home with basic supplies.
- For flattened ruching, thread a short length of swim-safe elastic through the existing casing with a seam ripper opened just enough to pass it through, then stitch the opening closed.
- For a loose seam, use a simple whip stitch or straight stitch in thread that matches the fabric’s stretch.
- Build a small kit ahead of time: a hand needle, polyester thread, a spool of swim elastic, and a seam ripper cover most repairs.
- If the fabric itself has thinned or torn beyond the seam, a professional is a better bet than a DIY patch, since a weak repair under tension can fail mid-swim.

Following the care label on the suit alongside these guides is the most reliable way to keep a scrunch bikini’s shape, color, and stretch intact for as many seasons as the fabric allows.
A realistic view on care, style, and how long swimwear lasts
Good care buys time, not immortality. A scrunch bikini washed in cold water, dried flat, and stored loosely will hold its shape and color far longer than one left to air-dry on a hook in the sun. But elastane is a consumable material: no amount of careful laundering can indefinitely prevent elastane degradation from repeated chemical exposure, so even a well-loved suit eventually loses its snap.
The honest goal is stretching a suit’s useful life by a season or two, not making it permanent. When a favorite finally goes slack, that’s the moment to check the brand’s newer scrunch styles rather than fight a losing battle with worn-out elastic.

FAQ
What is a Brazilian scrunch bikini?
A Brazilian scrunch bikini is a style with ruched fabric gathered by internal elastic, giving it a textured, scrunched look along the seams. The fit tends to run cheekier at the back, which is where the term “Brazilian” comes from in swimwear naming.
How can I take care of my bikini area?
For the bikini itself, rinse after each wear, hand-wash in cold water with a mild detergent, and lay it flat to dry rather than wringing or hanging it. This routine protects both the color and the elastic that holds the ruching in place.
How do you scrunch a bikini bottom?
The scrunch effect is built into the garment through an elastic-gathered seam, not something you create by hand each time you wear it. You can refresh flattened ruching by smoothing the gathers back into shape while the suit is slightly damp.
What is the Brazilian scrunch bikini ruching effect?
The ruching effect comes from elastic thread stitched inside a fabric casing, which pulls the material into soft gathers along the seam. This construction is also why ruched areas need gentler handling during washing, since stretching or scrubbing those seams can loosen the stitching over time.
