đŸ©ž Blood Stains on Clothes: Emergency Treatment to Perfectly Erase Even Coagulated Blood Without Fabric Damage

When a blood stain (bloodstain) gets on clothes, the most critical factors are 'time' and 'temperature.' The main component of blood, protein, coagulates the moment it touches hot water, setting firmly into the fibers, making it extremely difficult to remove afterward by any means. We share the emergency treatment know-how to remove blood stains without damaging the fabric.

🔑 Core Principle of Blood Stain Removal: Utilizing Cold Water and Enzymes

The most important rule to remember when removing blood stains is: 'Never use hot water.'

  • Cold Water: Essential for separating the blood protein from the fibers before it coagulates.
  • Enzymes: Utilize enzyme detergents that break down coagulated protein or substances with protein-degrading abilities.

💡 3-Step Formula for Blood Stain Emergency Treatment and Removal

1. ⏰ Emergency Treatment: Immediate Rinsing with Cold Water (Essential)

  • As soon as the blood stain occurs, use the coldest running water to flush the blood from the back of the stain toward the front, removing as much non-coagulated blood as possible.
  • Caution: Do not rub; rinse with the stream of water, pushing the blood stain out.

2. 🧮 Protein Breakdown: Utilizing Enzyme Detergent or Hydrogen Peroxide

  • If the stain is fresh (before coagulation):
    • Enzyme Detergent (containing Protease): Apply a laundry enzyme detergent to the stained area, let it sit for about 30 minutes, then pre-wash with cold water. (The enzymes dissolve the protein.)
  • If the stain is old (after coagulation):
    • Hydrogen Peroxide: Pour or dab hydrogen peroxide (available at pharmacies) onto the stain. The hydrogen peroxide reacts with the blood, creating foam that helps separate the protein.
    • Tip: When the foaming stops, rinse with cold water, and repeat the process until the stain disappears.
    • Caution: Hydrogen peroxide can cause bleaching on colored clothes or sensitive materials, so you must test it in an inconspicuous area before use.

3. đŸ«§ Final Wash: Wash and Dry with Cold Water

  • After confirming the blood stain is completely gone, the full wash must be conducted on the Cold Water Wash Cycle.
  • Drying: Never dry in a dryer or direct sunlight until you confirm the stain is completely removed. (Heat can set the stain.)

Blood stains are tricky to remove, but with just cold water and quick action, they can be cleaned successfully.
