How to Wash And Care For Swimwear: 10 Easy Hacks For Long-Lasting Costumes

There's something delightful about slipping into a swimsuit that fits like a second skin. Whether it's for a morning swim, a beach holiday in Goa, or simply lounging at a resort pool, swimwear is a wardrobe essential that deserves better care than it usually gets. Unfortunately, most people toss it into the washing machine, wring it hard, and then wonder why it loses shape within a season.

Good swimwear isn't cheap. A quality set can cost anywhere between ₹2,000 and ₹6,000, which means preserving it is as much about saving money as it is about style. The good news? Swimwear can last for years with the right TLC. It's not rocket science, just a handful of mindful habits that protect the fibres, preserve elasticity, and keep colours bold.

Here's a 10-point guide packed with practical hacks and washing rituals, perfect for anyone who loves their swim gear and wants to stretch its life without compromising on comfort or appearance.'

Simple Habits To Keep Your Swimwear Looking New

1. Rinse Immediately After A Swim

The biggest favour one can do for swimwear is rinsing it straight after a dip. Chlorine from pools and salt from seawater act like silent saboteurs, eating away at delicate fibres. If not rinsed quickly, they can make even the most expensive swimsuit sag and fade.

Picture this: a day at the pool ends, the body feels refreshed, but the swimwear silently soaks in chlorinated water until evening. By the time it's washed at home, half the damage is already done. A quick rinse under clean tap water at the pool shower can make all the difference.

It doesn't need to be fancy, just a 30-second swirl under running water to flush out harsh chemicals. For those heading back home, carrying a small bottle of clean water to rinse on the go can be a lifesaver. This tiny habit adds years to the life of a favourite swimsuit and is perhaps the simplest yet most overlooked hack.

2. Hand Wash Is Always Best

Swimwear and washing machines have an uneasy relationship. Those whirling drums may be perfect for everyday clothes, but swimwear fabrics, mainly nylon, elastane, and lycra, simply can't withstand the aggressive spinning. A single machine wash can stretch straps, loosen seams, and weaken elasticity.

Hand washing, though a bit old-school, works wonders. Fill a basin with cool water, add a teaspoon of mild detergent or even baby shampoo, and let the swimsuit soak for five minutes. Then gently rub the fabric between the palms without twisting or wringing. Think of it as giving the swimsuit a gentle massage rather than a vigorous scrub.

Hand washing is not only about preserving shape but also about keeping colours bright. Machines tend to dull prints faster, especially tropical florals and bold hues that are common in beachwear. With just 10 minutes of care, a swimsuit can stay as vibrant as it looked on the shop rack.

3. Use the Right Detergent

The secret ingredient in swimsuit care is not fancy, imported detergent but something gentler. Regular powders and liquids are loaded with harsh chemicals and optical brighteners that strip the delicate fabric of its stretch. Over time, this can turn a snug, flattering swimsuit into a saggy piece of cloth.

Instead, a mild detergent works best. Baby shampoo is surprisingly effective, it's soft, fragrance-friendly, and free from strong chemicals. Even a few drops of liquid handwash (without antibacterial additives) can do the trick. For those who swim regularly, investing in detergents specifically made for delicates, often priced around ₹200–₹400 a bottle, can be worthwhile.

Here's a useful trick: dissolve the detergent completely before adding the swimwear. Undissolved particles can cling to the fibres, leaving white patches or roughness. Remember, swimwear doesn't need deep cleaning like jeans or gym wear; it only needs a gentle rinse and a light cleanse to remove chlorine, salt, and body oils.

4. Avoid Hot Water at All Costs

Hot water may feel soothing after a long swim, but it's a nightmare for swimwear. Heat damages the elastic fibres, making them brittle and prone to losing their stretch. That explains why a swimsuit that was once snug suddenly feels loose after a few careless washes.

Cool or lukewarm water is the way to go. A soak in cold water not only protects the fabric but also helps lock in colours. Think of how dyed fabrics like silk sarees are always washed gently in cold water to avoid bleeding; swimwear deserves the same treatment.

Here's another tip: avoid steam ironing or blow-drying near heat sources. While it may be tempting to quick-dry after a beach trip, direct heat only accelerates wear and tear. Patience is key here. Letting swimwear air-dry naturally in a shaded spot can save hundreds of rupees in replacement costs.

5. Never Wring or Twist

After rinsing, the instinct is often to wring out excess water quickly. Unfortunately, twisting and squeezing stretch out the delicate elastic fibres, distorting the fit. The result? Straps that slide off shoulders and waistbands that don't hug the body the way they should.

The smarter way is simple: roll the swimsuit in a clean, dry towel. Place it flat, roll it up gently, and press lightly to absorb moisture. This method avoids damage while speeding up drying. For those in a rush, placing the towel-wrapped swimsuit under a ceiling fan works well.

The no-wring rule may feel tedious, but the payoff is worth it. A swimsuit that retains its original fit means fewer awkward adjustments at the poolside and more confidence while enjoying a swim. Comfort and appearance both depend on this small act of restraint.

6. Dry Flat in the Shade

Nothing fades a swimsuit faster than direct sunlight. Those bright rays may look perfect for drying clothes, but they are harsh on synthetic fibres, causing them to lose colour and elasticity quickly. A rich royal blue bikini can turn into a dull greyish shade in just one summer if dried under the sun every time.

The golden rule: dry flat in the shade. Spread the swimsuit on a clean towel, preferably on a flat surface like a table or balcony floor, and let the breeze do its work. Hanging it by the straps on a clothesline may seem convenient, but it stretches the fabric unevenly, leaving marks and droopy shapes.

If there's limited shade, even drying inside a well-ventilated room works fine. While it might take a little longer, the extra hours are a small price for swimwear that retains its colour and fit season after season.

7. Rotate Between Sets

Owning just one swimsuit and wearing it daily is like expecting a single pair of shoes to handle all occasions. Swimwear needs downtime to recover its elasticity after each use. Wearing the same set every day doesn't give the fibres a chance to spring back, and soon it loses its snug fit.

Having two or three options and rotating between them is a smart investment. Even if each costs around ₹2,500, the combined set can last twice as long as a single overused one. Plus, there's the added joy of variety, different colours and styles keep the swim experience fresh.

For those who swim regularly, say three or four times a week, rotation becomes even more essential. Think of it as giving each swimsuit a rest day, much like the body gets after a workout. In the long run, rotation saves money and keeps the wardrobe exciting.

8. Watch Out for Rough Surfaces

Swimwear looks delicate for a reason; it's not designed for sitting on rough poolside tiles, sandy rocks, or wooden benches. Those innocent-looking surfaces can snag and pull threads, leaving unsightly pilling or tiny holes that only get worse with time.

Carrying a lightweight cotton wrap or a beach towel is a clever hack. Whenever it's time to sit or lounge, simply spread it out first. This habit prevents accidental fabric damage while also adding a layer of comfort.

Think about it: spending ₹200 on a large beach towel saves the trouble of replacing a ₹3,000 swimsuit ruined by abrasions. A small precaution, yet it extends both style and savings. After all, swimwear deserves to be shown off, not hidden behind cover-ups just because the fabric has worn out prematurely.

9. Skip the Fabric Softener

Fabric softeners promise cloud-like softness for clothes, but for swimwear, they're the equivalent of poison. Softening agents coat the fabric, weakening its ability to stretch and cling. Over time, this coating builds up, leaving the swimsuit sticky, less breathable, and prone to damage.

Instead of using softeners, rely on gentle rinsing and proper drying. The fabric is naturally soft enough and doesn't need chemical enhancements. If there's a need to freshen it up, adding a teaspoon of white vinegar during the rinse can work wonders. Vinegar neutralises odours, removes detergent residues, and keeps the fibres smooth.

This natural alternative costs barely ₹50 for a small bottle and saves swimsuits from chemical overload. It's eco-friendly, budget-friendly, and far kinder to the body too. One simple swap keeps swimwear stretchy, vibrant, and fresh without unnecessary additives.

10. Store It Right

The way swimwear is stored often decides how long it lasts. Shoving it into a drawer, crumpled between jeans and t-shirts, is a recipe for losing shape. Elastane fabrics are sensitive and can crease permanently if folded roughly or squashed under weight.

The ideal method? Store swimsuits flat in a separate section of the wardrobe. If space is limited, rolling them gently instead of folding reduces stress on the fabric. For padded swim tops, avoid stacking heavy clothes over them, as the cups may get dented and lose their smooth shape.

Another pro tip is to use breathable cotton bags instead of plastic covers. Plastic can trap moisture and cause mildew, especially during monsoon months. A simple cotton pouch keeps the swimsuit safe, fresh, and ready to wear whenever the urge to dive strikes. After all, preserving it off-season is just as important as caring for it after every swim.
