How to care for your period panties: the ultimate guide

Investing in period underwear is a game-changer for reliable period comfort and protection.

To keep them in top condition and lasting for years, proper care is essential. If you've ever wondered how to wash and care for your period panties without damaging their absorbency, you're in the right place.

Follow these simple steps to make the most out of your reusable period underwear.  

Why proper care matters

Period underwear is designed with multi-layer technology to absorb menstrual fluid while keeping you feeling fresh. Washing them the right way ensures they last and perform for years to come—so you can rely on them every cycle.  

Step 1: Rinse immediately after use

After wearing your period underwear, rinse them under cold water until the water runs clear. This helps prevent stains and ensures that excess blood doesn’t set into the fabric.

Pro Tip: Never use hot water—it can lock in stains and reduce absorbency over time.  

Step 2: Machine or hand wash

✅ Use a gentle cycle with cold water and mild, fragrance-free detergent.
✅ Avoid fabric softeners and bleach, as they can damage the absorbent layers and reduce effectiveness.
✅ Prefer hand washing? Simply soak your period underwear in cold water with mild detergent for 15 minutes, then gently rub and rinse.  

Step 3: Air dry only

Tumble drying may be tempting, but heat breaks down the waterproof layers and elasticity of period panties. Instead, hang them up to air dry in a well-ventilated area. 

Pro Tip: Drying them in direct sunlight helps naturally disinfect and further neutralise odors.  

Step 4: Store them properly

Once completely dry, fold and store your period underwear in a clean, dry place—just like your regular underwear. Avoid sealing them in plastic bags.  

Common mistakes to avoid

❌ Using hot water (damages absorbency)  
❌ Washing with fabric softener (coats the fabric and prevents absorption)  
❌ Tumble drying (breaks down waterproof layers)  
❌ Skipping the rinse step (traps odors and stains)  

How long do period panties last?

With proper care, high-quality period underwear (like Fri Period 🩷) can last 2-3 years—making them an eco-friendly and cost-effective alternative to disposables. If you notice a decrease in absorbency or wear and tear, it might be time to replace them.
