How do you wash period underwear?

Period underwear is a game-changer for menstrual care—comfortable, eco-friendly, and reusable. But to keep them working well and looking fresh, proper washing is key. Here’s everything you need to know about how to wash period underwear, including dealing with blood stains (bleed material) effectively.

Why Proper Care Matters

Period underwear contains special absorbent layers designed to lock in menstrual fluid and prevent leaks. Washing them correctly:

  • Preserves absorbency

  • Prevents odors and stains

  • Keeps the fabric soft and comfortable

  • Extends the life of your underwear

Step 1: Rinse Immediately After Use

Rinse in cold water right after wearing to flush out blood (the main bleed material).

  • Use cold water because hot water can set blood stains, making them harder to remove.

  • Gently rub the stained area under running water to loosen dried blood.

Step 2: Soak for Stubborn Stains

For tougher stains, soak your period underwear in cold water for 20–30 minutes. You can add:

  • A small amount of mild detergent

  • A tablespoon of baking soda (helps break down stains and neutralize odors)

  • Or an oxygen-based stain remover (safe for delicate fabrics)

Step 3: Wash Gently

  • Hand wash: Use mild, fragrance-free detergent and gently scrub the underwear. Avoid wringing harshly.

  • Machine wash: Place underwear in a mesh laundry bag and wash on a gentle cycle with cold or warm water (never hot).

Important: Do NOT use fabric softeners or bleach—they can damage the absorbent layers and reduce effectiveness.

Step 4: Air Dry Naturally

  • Lay flat or hang your underwear to air dry.

  • Avoid tumble drying, ironing, or exposing them to direct heat/sunlight for long periods, as heat can break down technical fabrics and absorbency.

Bonus Tips for Managing Blood (Bleed Material) Stains

  • Treat stains quickly — the sooner you rinse, the easier it is to remove them.

  • For dried stains, gently rub a paste of baking soda and water on the spot before washing.

  • Avoid harsh scrubbing or chemicals that can damage fabric.

  • If stains persist, repeating the soak and wash process usually helps.

Why This Works

Blood is a protein-based stain, which reacts poorly to heat but can be broken down by cold water and gentle detergents. Proper care keeps your period underwear performing their best, cycle after cycle.
