Blood stain treatment: Step-by-step

he following blood stain removal tips will show you how to clean blood from fabric that isn’t delicate (like jeans, cotton underwear, or your favorite t-shirt). It will also work to remove dry blood stains from your clothes, but you may need to repeat the process more often. 


  1. Before we get started, remember to wear gloves when handling blood that is not yours.
  2. If the stain has dried, remove any excess blood with a spoon or the dull side of a knife. 
  3. Turn the fabric over so the stain is face-down and flush the stain out under cold water. Never use hot water on blood, as this will cause the stain to set.
  4. Pre-treat the stain by applying Persil® liquid detergent directly to the front side of the stain and letting it sit for five minutes. Choose the detergent that is most appropriate for the type of laundry that’s been stained. Make sure to check first for color fastness in an inconspicuous area on your colored clothing. 
  5. Wash the fabric with Persil® immediately to prevent the stain from setting. Follow the dosage for ‘heavily soiled’ garments on the product’s instructions.
  6. Check the bloodstained clothing to see if the stain is gone before drying. Drying the garment before the stain has been removed may cause it to set permanently. 
  7. Repeat the process as necessary.
