Do you wash period underwear?

Yes—Here’s Exactly How to Do It (And Know It’s Really Clean)


Period underwear is a reusable, eco-friendly alternative to pads and tampons—but to get the most out of it, proper washing is essential.

In this blog, we’ll explain:
✔️ How to wash period underwear
✔️ How to tell it’s clean
✔️ How to care for it long-term
✔️ Common mistakes to avoid


🧺 Do You Need to Wash Period Underwear?

Absolutely. After each wear, your period underwear must be washed just like any other reusable hygiene product.

Washing it properly ensures:

  • It stays hygienic and safe for your body

  • It keeps its absorbent power

  • It lasts for 1–2 years or more


🧼 How to Wash Period Underwear: Step-by-Step

Here’s a simple routine to keep your period underwear clean:

1. Rinse Immediately (or ASAP)

After wearing, rinse your underwear in cold water until the water runs mostly clear. This helps remove most of the blood and prevents stains.

Pro tip: Don’t use hot water yet—it can set stains.


2. Soak (Optional for Heavy Flow Days)

If you wore the underwear for a long time or had a heavy flow, soak it in cold water for 30 minutes. This loosens any remaining blood before washing.


3. Machine Wash or Hand Wash

  • Machine wash: Use a gentle/delicate cycle with cold water and mild detergent

  • Hand wash: Use cold water and gently rub with your fingers and detergent

🚫 Avoid bleach or fabric softener—they damage the absorbent layers.


4. Air Dry Only

  • No dryers—high heat breaks down the leak-proof fabric

  • Lay flat or hang dry in a well-ventilated area


✅ How Do You Know It’s Really Clean?

Your period underwear is clean when:

  • There’s no visible blood

  • There’s no odor

  • The fabric feels fresh and dry after air drying

If your underwear still smells after drying, you may need to:

  • Wash it again with mild detergent

  • Soak it longer next time

  • Avoid using too much detergent, which can build up over time


❌ Common Mistakes to Avoid

Mistake Why It’s Bad
Using hot water first Sets the stain into the fabric
Using bleach/fabric softener Destroys absorbent technology
Skipping the rinse Leaves blood residue and odor
Machine drying Shortens product lifespan

🩲 How Many Times Can You Reuse Period Underwear?

With proper care, period underwear can last up to 2 years or more. Brands like NYX Collection use 4-layer leak-proof tech and durable fabrics designed to handle repeated wash cycles.

Yes, you absolutely should wash period underwear after every wear. With a simple rinse, wash, and air-dry routine, you’ll keep your underwear clean, fresh, and long-lasting—while also doing the planet a favor.
