How to Wash & Care for Period Underwear: The Complete Guide
One of the best things about period underwear? It's reusable.
That means:
- ♻️ Better for the planet — no more throwing away hundreds of pads and tampons
- 💰 Better for your budget — one-time investment vs. monthly expenses
- 💙 Better for your body — safe, non-toxic fabrics you can trust
But here's the question we get asked most: "Isn't washing period underwear... gross?"
The honest answer: Not at all. It's actually easier (and less messy) than dealing with disposable products.
With the right care routine, your Cheeki will stay fresh, absorbent, and long-lasting cycle after cycle — for years to come.
Here's exactly how to wash period underwear, step by step.
The Simple 3-Step Care Routine
Step 1: Rinse in Cold Water ❄️
After wearing your period underwear, rinse it in cold water until the water runs clear.
How to do it:
- Hold the underwear under cold running water (sink or shower works great)
- Gently squeeze and rinse the absorbent gusset area
- Continue until the water running through is clear (usually takes 30-60 seconds)
Why cold water?
- Prevents blood stains from setting
- Protects the absorbent layers from damage
- More effective at removing blood than hot water (hot water actually "cooks" protein stains in)
Pro tip: Don't skip this step! Rinsing first makes machine washing way more effective and keeps your underwear fresher.
Step 2: Machine Wash on Gentle Cycle 🧺
After rinsing, toss your period underwear in the washing machine with your regular laundry.
Yes, really! You can wash them with your other clothes.
Best practices for machine washing:
✅ Use cold water — protects fabrics and absorbency
✅ Choose gentle/delicate cycle — preserves the leak-proof layers
✅ Use mild, gentle detergent — free of harsh chemicals
✅ Put them in a wash bag (optional but recommended — more on this below!)
What to AVOID:
❌ No bleach — damages fabrics and reduces absorbency
❌ No fabric softener — creates a coating that blocks absorbency
❌ No hot water — can break down the leak-proof barrier over time
❌ No harsh detergents — stick to gentle, fragrance-free options when possible
Wait, can I really wash them with my regular clothes?
YES! After you've rinsed them, there's no more blood to worry about. They're just underwear at that point. Toss them in with towels, jeans, t-shirts — whatever you're washing.
Step 3: Air Dry for Best Results 🌬️
To keep the leak-proof layers working properly, always air dry your period underwear.
How to air dry:
- Hang them on a drying rack, clothesline, or shower rod
- Lay them flat on a clean towel
- Clip them to a hanger
Why air dry?
- High heat from dryers can wear down the waterproof barrier
- Air drying extends the lifespan of your underwear significantly
- It's gentler on the elastic and absorbent layers
How long does it take?
Usually 4-12 hours depending on humidity and air circulation. Overnight drying works great!
Can I EVER use a dryer?
We don't recommend it, but if you're in a pinch, use the lowest heat setting possible. Just know that repeated high-heat drying will shorten the lifespan of your underwear.
Make Washing Even Easier: Use a Wash Bag
The Cheeki Wash Bag is a total game-changer — especially for teens, first-time users, or anyone who wants to make laundry as simple as possible.
Why You'll Love a Wash Bag:
✅ Keeps your period underwear protected in the washing machine
✅ Prevents tangling with other clothes
✅ Extends the lifespan of your underwear by reducing wear and tear
✅ Makes laundry stress-free — just toss the whole bag in
✅ Great for travel — doubles as a storage pouch
✅ Perfect for teens — simple, discreet, and easy to use
How to use it:
- Rinse your period underwear as usual
- Place them in the Cheeki Wash Bag
- Zip it closed
- Toss the whole bag in the washing machine
- Air dry after washing
That's it. No mess, no fuss, no worrying about your underwear getting damaged.
Common Questions About Washing Period Underwear
"Do I have to rinse them right away, or can I wait?"
You CAN wait — but the sooner you rinse, the easier it is and the better your underwear will look long-term.
If you can't rinse immediately:
- Place them in a small wet bag or waterproof pouch
- Rinse them when you get home (even a few hours later is fine)
- Don't let them sit for days — rinse within 24 hours for best results
"Can I soak them overnight instead of rinsing?"
You can, but you don't need to.
A quick cold water rinse (30-60 seconds) is just as effective and way easier. Soaking overnight is overkill for most people.
If you prefer to soak:
- Use cold water
- Add a tiny bit of gentle detergent if you want
- Soak for 30 minutes to a few hours (not necessary to go overnight)
"What detergent should I use?"
Best choices:
- Gentle, fragrance-free detergents
- Plant-based or eco-friendly options
- Regular mild detergent (like what you'd use for delicates)
Avoid:
- Harsh chemical detergents
- Anything with fabric softener built in
- Detergents with strong fragrances or dyes
Popular options that work well:
- Seventh Generation Free & Clear
- Tide Free & Gentle
- All Free Clear
- Any gentle detergent labeled "for sensitive skin"
"Can I use stain remover on them?"
Yes, but stick to gentle options.
If you notice a stubborn stain:
- Try a gentle stain stick or spray
- Avoid bleach-based stain removers
- Test on a small area first
- Remember: slight discoloration doesn't affect performance!
Pro tip: Most "stains" are just slight discoloration and don't impact how well your underwear works. Don't stress about achieving perfect white fabric.
"How do I know if I'm washing them correctly?"
Your period underwear should: ✅ Smell fresh and clean after washing
✅ Feel soft and absorbent
✅ Still have a slight waterproof barrier feel in the gusset
✅ Look mostly clean (slight discoloration over time is normal)
Red flags that something's wrong: ❌ Strong odors even after washing (you might need to rinse more thoroughly or check your detergent)
❌ Reduced absorbency (could mean fabric softener buildup or damage from high heat)
❌ Stiff, rough texture (too much detergent or hard water buildup)
"Can I hand wash them instead of machine washing?"
Absolutely! Hand washing is totally fine and can even be gentler.
How to hand wash:
- Rinse in cold water as usual
- Fill a sink or basin with cold water and a small amount of gentle detergent
- Gently agitate and squeeze (don't wring or twist aggressively)
- Rinse thoroughly with clean cold water
- Gently squeeze out excess water
- Air dry
How Many Pairs Do You Need?
To comfortably rotate through your cycle, we recommend having 3-5 pairs.
Sample Rotation:
Light to Moderate Flow:
- 2-3 Medium Flow pairs for daytime
- 1-2 Heavy Flow pairs for overnight or heavy days
Heavy Flow:
- 1-2 Medium Flow pairs for lighter days
- 3-4 Heavy Flow pairs for maximum coverage
Teens & First Periods:
- Start with 3 pairs total (1-2 Medium, 1-2 Heavy)
- Add more as you figure out your flow patterns
Why Multiple Pairs Matter:
✓ Always have a clean pair ready
✓ Can wear one while others are washing/drying
✓ Reduces stress about laundry timing
✓ Ensures you're covered for your entire cycle
Our Starter Kits are designed to give you the perfect rotation — no guesswork required!
How Long Does Period Underwear Last?
With proper care, CheekiWear can last 2-3 years or longer.
That's 2-3 YEARS of:
- No buying pads or tampons
- No running to the store mid-cycle
- No throwing away hundreds of disposable products
- Just comfortable, reliable protection
Tips to Maximize Lifespan:
✅ Rinse before washing — prevents buildup and staining
✅ Always air dry — preserves the leak-proof barrier
✅ Use a wash bag — protects from snags and damage
✅ Avoid fabric softener — maintains absorbency
✅ Rotate pairs — reduces wear on any single pair
✅ Store properly — keep in a dry, cool place between uses
Signs It's Time to Replace:
- Absorbency has significantly decreased
- Visible wear, holes, or damaged elastic
- Leak-proof barrier no longer works effectively
- Fabric feels rough or damaged even after proper washing
Remember: Slight discoloration or fading over time is normal and doesn't mean you need to replace them!

Washing Tips for Different Situations
For Teens & First-Time Users:
- Use a wash bag — makes the process simple and discreet
- Set a routine — rinse after school, wash with regular laundry
- Keep it private — wash bags mean your underwear isn't on display in the laundry

For Travel:
- Bring a small wet bag or waterproof pouch for used underwear
- Rinse in the hotel sink or shower
- Pack a Cheeki Wash Bag for easy hand washing on the go
- Air dry using a towel or hang in the bathroom
- Bring enough pairs so you don't have to wash mid-trip
For Busy Parents:
- Batch rinse — have your daughter rinse them right after use, then you can toss them all in the wash together
- Teach independence — teens can absolutely learn to rinse and wash their own
- Use wash bags — makes it easier for kids to manage their own laundry
- Keep extras — having 5+ pairs means less frequent washing urgency
The Environmental Impact of Reusable Care
Let's talk about what proper care really means:
By washing and reusing Cheeki, you're saving:
📊 200+ disposable pads/tampons per year from landfills
📊 Thousands of products over a lifetime
📊 Hundreds of dollars in ongoing costs
📊 500+ years of decomposition time for disposables you're NOT using
Washing period underwear uses:
- A tiny fraction of water compared to manufacturing disposables
- Less energy than producing, packaging, and shipping single-use products
- No harmful chemicals going into waterways
The math is simple: Reusable products are better for the planet, even with washing.
