Can you wash period underwear in a washing machine?

Yes, you can absolutely wash period underwear in a washing machine — and it's one of the reasons why they’re such a convenient and eco-friendly alternative to disposable products.

However, there are a few important steps to follow to make sure they stay clean, odor-free, and long-lasting.

🧺 How to Wash Period Underwear in a Washing Machine (Step-by-Step)

✅ Step 1: Rinse Immediately After Use

  • Rinse with cold water until the water runs mostly clear.

  • This helps remove excess blood and prevents stains from setting.

  • Avoid hot water at this stage — it can set the blood into the fabric.

✅ Step 2: Machine Wash (Cold or Gentle Cycle)

  • Put the rinsed underwear in a mesh laundry bag (optional but recommended).

  • Wash with similar dark colors on a cold or gentle cycle.

  • Use mild, fragrance-free detergent.

❌ Avoid:

  • Fabric softeners (can damage absorbent layers)

  • Bleach (harsh on fabrics and skin)

  • High-heat wash or heavy-duty cycles

✅ Step 3: Air Dry

  • Hang or lay flat to dry.

  • Avoid tumble drying, as heat can break down the absorbent materials over time.

  • Drying in sunlight can help naturally disinfect and reduce odor.

🩲 Extra Tips for Keeping Period Underwear Fresh

  • Have 3–5 pairs in rotation to avoid overuse and extend life.

  • If odor builds up, soak in a mix of water and vinegar (1:2 ratio) for 30 minutes before washing.

  • Store dry underwear in a cool, dry place — not sealed in plastic.
