How to wash out period blood underwear?

Period blood stains can seem tough to remove, but with the right care, your underwear can look fresh again. Here’s how:

Step 1: Rinse Immediately with Cold Water

  • Rinse your underwear under cold running water as soon as possible to flush out as much blood as you can.

  • Avoid hot water, as it can set the stain permanently.

Step 2: Pre-Soak in Cold Water

  • Fill a basin or sink with cold water.

  • Soak your underwear for 30 minutes to an hour to loosen the dried blood.

  • For stubborn stains, add a mild detergent or oxygen-based stain remover (like OxiClean) to the soak.

Step 3: Gently Rub the Stain

  • After soaking, gently rub the stained area between your fingers to help lift the blood.

  • Be gentle to avoid damaging delicate fabrics, especially with period underwear that has special layers.

Step 4: Wash with Mild Detergent

  • Hand wash or machine wash on a gentle cycle with cold water.

  • Use a mild, fragrance-free detergent without bleach or fabric softeners, which can damage fabric and waterproof layers.

  • If machine washing, consider using a mesh laundry bag to protect your underwear.

Step 5: Inspect and Repeat if Needed

  • After washing, check if the stain is gone.

  • If still visible, repeat soaking and gentle rubbing before drying.

Step 6: Air Dry Completely

  • Air dry your underwear flat or hang in a shaded, well-ventilated area.

  • Avoid tumble drying or direct sunlight to preserve fabric integrity.

Bonus Tips:

  • For natural stain removal, you can apply a paste of baking soda and water to the stain before soaking.

  • White vinegar added to the rinse cycle helps deodorize and brighten fabric.

  • Avoid using chlorine bleach, especially on colored or special period underwear.

Following these steps helps keep your period underwear clean, stain-free, and comfortable for repeated use.
