How to Wash Period Underwear in 4 Steps

  1. Rinse in cold water

    Rinse it under cold water soon after you take it off. If you are out, rinse it when you get home. Squeeze it gently until the water runs clear.

  2. Wash cold on gentle

    Wash it with like colors in cold water on a gentle cycle. A mesh laundry bag can help protect it.

  3. Skip softener and bleach

    Fabric softener can coat the layers and make them soak up less. Bleach can harm the fabric.

  4. Air dry fully

    Hang it or lay it flat to dry, away from direct heat. The layers take the longest, so make sure it is dry all the way through.

What If Period Underwear Stains?

Rinse it in cold water as soon as you can. The sooner you rinse, the easier the blood comes out. Do not use hot water, since heat can set the stain.

If stains worry you, pick a dark color. Kischt Noir (black) and Bordeaux (maroon) show stains less.

Can You Put Period Underwear in the Dryer?

Air drying is the gentle choice. Heat can wear out stretchy fabric over time. Hang it on a rack, or lay it flat on a towel. Check the care label before you use a dryer.
