You clean period underwear by rinsing them in cold water right after use, then washing on a gentle, cold cycle (or by hand) with mild detergent, and air‑drying completely—no bleach, fabric softener, or high heat. Done right, they stay absorbent, odor‑free, and can last for years.

Quick Scoop

  • Rinse in cold water until it runs clear to prevent stains from setting.
  • Wash on a gentle, cold cycle (or hand‑wash) with mild detergent, no bleach or fabric softener.
  • Always air‑dry flat or on a line; avoid tumble dryers and radiators to protect the absorbent layers.

Step‑by‑step wash routine

  1. Right after you take them off
    • Rinse under cold running water and gently squeeze the gusset until the water runs clear; avoid hot water because it can set blood and reduce absorbency.
 * If you can’t rinse immediately, store them in a breathable or wet bag (not soaking in water) until you get home.
  1. Main wash (machine or hand)
    • Put them in a laundry bag and wash with similar darks on a gentle cycle at cold or up to about 30°C with a mild detergent.
 * Skip bleach, fabric softener, and strong stain removers, which can break down the absorbent fibers and irritate skin.
  1. Drying them properly
    • Gently press out excess water (no twisting) and lay flat or hang to air‑dry in a well‑ventilated spot, out of direct high heat.
 * Make sure they are fully dry before wearing again to avoid odor and keep the layers working well.

Deep‑clean & odor rescue

Sometimes period underwear can hold onto a slight smell or shadow stains even if you wash them regularly. An occasional gentle deep clean helps refresh them without ruining the fabric.

  • Baking soda soak: Fill a basin with cold water and add 2–3 tablespoons of baking soda, then soak for several hours or overnight before washing as usual.
  • Vinegar rinse: After washing, some guides suggest a brief rinse in cold water mixed with white vinegar to help neutralize odors and remove detergent residue, then rinse again with plain water.

Tips from users & forums

People who use period underwear regularly share practical tricks that go beyond the care label.

  • Many users find a quick cold rinse in the shower easiest, then they toss the underwear into a small “period laundry” basket to wash later.
  • Forum discussions often mention that as long as you avoid hot water, harsh products, and dryers, most brands behave similarly and last longer.
