What is the best way to wash period undies?

eriod underwear is designed with special absorbent layers to catch menstrual flow, so washing them well ensures hygiene, odor control, and durability.

Step 1: Rinse Immediately After Use

  • Rinse in cold water right after wearing to prevent stains from setting.

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

Step 2: Soak (Optional)

  • If you can’t wash them right away, soak period underwear in cold water for 30 minutes to a few hours.

  • You can add a bit of gentle detergent or oxygen-based stain remover for tough stains.

  • Avoid chlorine bleach or fabric softeners as they can damage the fabric and absorbency.

Step 3: Hand Wash or Machine Wash

Hand Wash (Recommended for Delicate Care)

  • Use mild, fragrance-free detergent.

  • Gently rub the fabric to clean; don’t wring or twist aggressively.

  • Rinse thoroughly with cold water until no soap remains.

Machine Wash

  • Turn underwear inside out.

  • Use a laundry bag for delicate items to reduce friction.

  • Choose a gentle or delicate cycle with cold water.

  • Use a mild, bleach-free detergent.

  • Avoid fabric softeners and bleach—they reduce absorbency and damage fabric.

Step 4: Dry Properly

  • Air dry period underwear in the shade.

  • Avoid tumble drying, as high heat can damage the elastic and waterproof layers.

  • Do not iron or dry clean.

Additional Tips

  • Do not use hot water or bleach: Both can break down the special fabrics and make stains permanent.

  • Avoid fabric softeners: They coat the fibers and reduce absorbency.

  • Check care labels: Always follow the manufacturer’s specific washing instructions.

  • Use stain remover cautiously: Oxygen-based stain removers are usually safe, but always test on a small area first.

Why Wash Period Underwear This Way?

  • Gentle washing preserves the underwear’s unique absorbent layers.

  • Cold water and mild detergent prevent stains from setting and maintain freshness.

  • Air drying extends the lifespan and keeps fabrics breathable.
