Your period swimwear can last through an impressive 200 to 250 washes without losing its absorbency or quality – but only if you care for it properly. As someone who has spent countless hours testing swimwear fabric against the Hawaiian waves, I've seen firsthand how crucial proper care is for high-performance gear.
Here's the thing: many of us unknowingly damage our period bathing suits with simple washing mistakes. Using hot water, for example, causes blood to bond with the fabric, creating stubborn stains that are nearly impossible to remove. Frankly, it's one of the fastest ways to shorten your swimwear's life.
Key Takeaways
- Rinse Cold, Rinse Fast: Always rinse your suit in cold water immediately after use. This single step is crucial for preventing stains and preserving the fabric's integrity.
- Gentle Washing is Key: Use a mild detergent and a delicate cycle (or hand wash). Strictly avoid bleach and fabric softeners, as they destroy the suit's absorbent technology.
- Air Dry Only: Never put period swimwear in a machine dryer. Heat is the enemy, as it will irreparably damage the waterproof and elastic fibers.
- Proper Storage Matters: Ensure the suit is 100% dry before storing it in a cool, dry place to prevent mildew and maintain its shape and function for years.
The good news is that caring for your period swimwear doesn't have to be complicated. These innovative garments can absorb up to 3 teaspoons of menstrual fluid – equivalent to about three tampons worth of blood – and they're designed with multiple specialized layers that prevent leaks while conforming to your body. To keep them working effectively, however, they need the right care.
So, whether you're wondering how to hand wash period swimwear or how to properly care for your first pair, we'll walk through exactly what you need to know. Let's dive in.
What Is Period Swimwear and How Does It Work?
Period swimwear is a relatively new innovation that allows you to swim confidently during your cycle without relying on tampons or cups. From the outside, it looks just like regular swimwear, but it contains hidden, specialized technology that makes all the difference.
But how exactly does period swimwear absorb blood but not water?
The magic happens through a unique multi-layered design. Most period swimwear, including Beautikini's, features three or four distinct layers working in perfect harmony:
- Moisture-wicking top layer: Sits closest to your body and quickly pulls moisture away from your skin for comfort.
- Absorbent middle layer: This is the core that absorbs and locks in menstrual blood, often capable of holding 2-3 tampons' worth of fluid. This is confirmed by research from institutions like the National Science Foundation, which supports textile innovations.
- Waterproof outer layer: Creates a durable barrier that prevents blood from leaking out and, critically, stops water from getting in.
How is period swimwear different from period underwear?
While period swimwear and period underwear share similar core technology, they are engineered for vastly different environments. The primary distinction lies in their interaction with water.
| Feature | Period Swimwear | Period Underwear |
|---|---|---|
| Primary Use | Water activities (swimming, surfing) | Daily dry wear |
| Waterproofing | Features a robust waterproof outer layer to block water entry | Typically lacks a fully waterproof layer; not designed for submersion |
| Absorption Capacity | Light to moderate (approx. 2-3 tampons' worth) | Moderate to heavy (up to 6 tampons' worth) |
| Drying Time | Made with quick-drying materials for comfort after swimming | Not optimized for rapid drying |
Will period swimwear work for bladder leaks?
Yes! The versatile absorbent technology in period swimwear can effectively manage light bladder leaks alongside menstrual flow. The layers that capture menstrual blood work similarly for urine, offering a dual-purpose solution for those experiencing light incontinence.
However, it's vital to be realistic about capacity. Since bladder leaks can sometimes involve more fluid than a typical menstrual flow, period swimwear might not provide sufficient protection for moderate to heavy incontinence. For heavier flow or leak days, some women find success combining period swimwear with an internal product like a menstrual cup for extra peace of mind.
Step 1: Rinse Immediately After Use
The moment you take off your period swimwear, the clock starts ticking. In my experience as a competitive swimmer, I learned that what you do in the first 30 minutes after leaving the pool determines the lifespan of your suit. Prompt rinsing isn't just a good idea—it's essential.
Why Cold Water Is Your Best Friend
Cold water is non-negotiable. It breaks down blood and prevents it from setting into the fabric. Hot or even warm water does the opposite: it acts like a bonding agent, setting blood stains permanently and making them nearly impossible to remove. This is a basic principle confirmed by textile care experts and institutions like the American Cleaning Institute.
But it's not just about stains. Cold water preserves the delicate layered fabrics and their absorption capabilities. The specialized materials that make your period swimwear effective can degrade significantly when exposed to heat. Rinsing also helps remove other damaging substances:
- Chlorine from pool water, which can "eat" fabric over time
- Salt from ocean swimming
- Body oils and sunscreen residue
How to Rinse: Sink or Shower Method
You have two effective options:
Sink Method:
- Fill your bathroom sink with cold water.
- Submerge your period swimwear completely.
- Gently squeeze the fabric (never wring or twist).
- Continue soaking and squeezing until the water runs clear.
- Drain and give it a final rinse under running cold water.
Shower Method: This is often more convenient. Simply hold your swimwear under the cold shower stream and gently squeeze until all blood is removed and the water runs clear. Try to do this within an hour of taking off your swimwear—don't let it sit in a laundry basket.
Myth vs. Reality
Myth: Letting the swimsuit dry first makes stains easier to treat later.
Reality: This is the worst thing you can do for blood stains. As a former NCAA swimmer who dealt with this constantly, I can tell you that dried blood is a nightmare. The proteins in blood denature and bond to fibers when they dry and especially when heated, creating a permanent chemical change. The delicate, high-tech fibers in period swimwear are particularly susceptible. Rinsing with cold water while the blood is still fresh is the only way to ensure it washes out completely, preserving both the look and function of your suit.
Step 2: Wash Gently for Best Results
After that crucial initial rinse, you're ready for the actual washing. Both machine and hand washing are effective for period swimwear – it really just depends on your routine and preference.
Can You Machine Wash Period Swimwear?
Yes! Contrary to popular belief, most modern period swimwear is durable enough for the washing machine, provided you follow these steps:
- Always use a mesh laundry bag. This is critical for protecting your swimwear from snagging and tangling.
- Choose a gentle or delicate cycle with cold water.
- Select a low spin setting to protect the technical materials.
- Wash with similar lightweight items – no need for a separate load, but avoid washing with heavy items like jeans or towels.
How to Hand Wash Period Swimwear
Hand washing is undoubtedly the gentlest option and my personal recommendation for maximizing your swimwear's lifespan. It's also perfect for travel.
Here's the simple process:
- Fill a basin with cold water and add a small amount of mild detergent.
- Submerge your swimwear and let it soak for 15-20 minutes.
- Gently agitate the water and squeeze the fabric.
- Rinse thoroughly with clean, cold water until all soap is gone.
- Gently press out excess water – again, do not wring or twist.
What Detergent Should You Use?
The right detergent is crucial. You need something that cleans effectively without damaging the specialized absorbent layers. My go-to is a pH-neutral, plant-based liquid detergent.
Good options include:
- Mild, pH-neutral, unscented detergents
- Specialized detergents for activewear or delicates
- Plant-based detergents free from harsh chemicals
Absolutely avoid these:
- Fabric softeners: They leave a waxy residue that clogs the pores in the absorbent layers, rendering them useless.
- Bleach (any kind): It breaks down the fibers that create the leak-proof barrier, leading to catastrophic failure.
- Powdered detergents: They can sometimes leave a residue that doesn't fully rinse out, irritating skin and fabric.
Remember: the technology relies on these fibers staying intact. Gentle care keeps everything working as it should.
Step 3: Drying Without Damage
How you dry your period swimwear is just as important as how you wash it. This simple step is where many people accidentally cause irreversible damage.
Why Air Drying Is The Only Way
Let me be direct: air drying isn't just recommended – it's the only safe way to dry period swimwear. Every single brand agrees on this. The intense, direct heat from a machine dryer is the number one enemy of performance fabrics.
High temperatures destroy the waterproof layer, weaken the elastic fibers, and compromise the absorbent materials. You might not notice the damage after one accidental tumble, but repeated heat exposure will gradually ruin the suit's effectiveness. Air drying preserves the seams, the gusset, and the vital leak-proof technology.
How Long Does It Take to Dry?
Honestly, it varies. Period swimwear can take anywhere from 6 to 48 hours to dry completely, depending on:
- Environmental humidity (it takes much longer in tropical climates)
- Air circulation in your space
- The thickness of the fabric
For most people, a suit will dry within 24 hours when hung properly. This makes it practical to have just two pairs in rotation during your cycle.
How to Speed Up Drying Naturally
Want to dry your suit faster without damage? Here are a few pro-tips:
- The Towel Roll: After washing, lay your suit flat on a clean, dry towel. Roll the towel up tightly with the suit inside and press gently. This wicks away a surprising amount of water and can cut drying time in half.
- Turn It Inside-Out: Before hanging, turn your swimwear inside-out. This exposes the thicker, more absorbent layers directly to the air.
- Maximize Airflow: Hang it in a well-ventilated area. A spot with a gentle breeze is ideal. Avoid stuffing it in a cramped bathroom.
Just make sure your swimwear is 100% bone dry before storing it. This is critical for preventing the mildew and odors that can develop in damp garments.
Step 4: Storing and Maintaining Longevity
Once your suit is completely dry, proper storage is the final step in protecting your investment. How you store it between wears directly impacts its performance and longevity.
How to Store Period Swimwear Properly
First, ensure the suit is absolutely, 100% dry. Storing even slightly damp swimwear creates a breeding ground for mildew and bacteria, leading to unpleasant odors and fabric deterioration. Store it in a cool, dry place away from direct sunlight, which can fade colors and degrade fibers over time.
Avoid tightly folding or compressing your swimwear. Instead, try these methods:
- Lay it flat in a drawer.
- Hang loosely on a smooth, non-metal hanger.
- Roll it gently to preserve the fabric's elasticity.
How long does period swimwear last?
With proper care, quality period swimwear is engineered to last for 200-250 washes. For most people, this translates to about five years of regular use, making it a very sustainable and cost-effective choice.
Of course, its actual lifespan depends on usage frequency, care consistency, and material quality. Following the routine we've outlined helps you get the maximum value from your investment.
Signs It's Time to Replace Your Swimwear
Even with perfect care, all technical garments eventually wear out. Watch for these signs:
- Reduced Absorption: If you notice leaks on a normal flow day, the absorbent layers may be compromised.
- Stretched Fabric: Pay attention to the elastic at leg openings and waistbands. If it feels loose, the fit is compromised.
- Persistent Odors: If a smell remains even after a vinegar soak and proper washing, bacteria may be permanently embedded.
- Visible Damage: Obvious tears, holes, or separated seams mean the waterproof barrier is breached.
Recognizing these signs early helps you replace your swimwear before you're caught with a leak, ensuring you always have reliable protection.
Your Confidence is Worth the Care
Caring for your period swimwear truly boils down to a few simple habits: rinse cold, wash gently, air dry completely, and store properly. In my experience, once you build this routine, it becomes second nature—a small ritual that protects the gear that gives you freedom.
When you take a moment to care for your suit, you're not just doing laundry; you're preserving a piece of technology that empowers you. You're ensuring that the next time you want to hit the waves, play pickleball, or just lounge by the pool, nothing holds you back. Remember, confidence is the best outfit, and it performs best when it's well-cared-for.

Frequently Asked Questions
Q1: How do I properly clean my period swimwear?
The best method is a 3-step process: First, rinse your period swimwear in cold water immediately after use to remove blood, chlorine, or salt. Then, wash it gently using a mild detergent, either by hand or in a washing machine on a delicate cycle. Finally, always air dry. Crucially, avoid hot water, fabric softeners, or bleach, as these can permanently damage the swimwear's absorbent layers and waterproof barrier.
Q2: Can I put my period swimwear in the dryer?
No, you should never put period swimwear in the dryer. The high heat is the fastest way to ruin the delicate technology. It can damage the waterproof layer, weaken elastic fibers, and compromise the absorbent materials. The only safe method is to air dry your swimwear by hanging it or laying it flat in a well-ventilated area.
Q3: How does period swimwear prevent water absorption while swimming?
Period swimwear uses a multi-layered gusset with a special waterproof outer layer that prevents pool or ocean water from entering the absorbent core. When the swimwear fits snugly against your body, it creates a secure seal around your legs and waist. This allows the inner layers to absorb menstrual fluid without becoming saturated with water.
Q4: Is period swimwear hygienic for swimming in public pools?
Absolutely. When used and cared for correctly, period swimwear is a completely hygienic option for swimming. The specialized layers are engineered to absorb and trap menstrual fluid, preventing it from leaking into the water. It's just as hygienic as using a tampon or menstrual cup while swimming.
Q5: How long does period swimwear typically last?
With proper care, high-quality period swimwear like Beautikini's is designed to last for 200-250 washes. For most people, this translates to approximately five years of regular use. The actual lifespan depends on how often you wear it, how closely you follow care instructions, and its exposure to harsh elements like chlorine.
Q6: Do I need a special detergent for period swimwear?
You don't necessarily need a 'special' detergent, but you do need a *mild* one. A gentle, pH-neutral, and unscented liquid detergent is ideal. The most important thing is to avoid any detergents containing fabric softeners, bleach, or harsh optical brighteners, as these chemicals will clog the absorbent fabric and break down the waterproof barrier over time.
Q7: How can I get a musty smell out of my period swimwear?
A musty smell usually means the suit wasn't dried completely before storage, or there's some bacteria buildup. To fix this, try soaking your swimwear for 30 minutes in a cold water solution with a quarter-cup of white vinegar. After soaking, wash it as usual with a mild detergent and ensure it air dries completely in a well-ventilated area before storing.
