To remove blood from jeans, act quickly. Rub the stain out with a wash cloth soaked in cold water. If this method fails to totally remove the blood stain, use undiluted vinegar. If the stain remains, remove it by using cold water, salt and a toothbrush.
- Rub the stain with cold water
Soak a wash cloth in cold water, and rub the stain. Rinse the rag, and repeat. If the stain comes out completely, launder the jeans as you regularly would. Do not use hot water because doing so sets the stain in.
- Saturate the stain with vinegar
If any of the stain remains, saturate it with undiluted white vinegar. Allow the vinegar to sit on the stain for 20 minutes, and rinse. If the stain is gone, wash the jeans as you normally would.
- Soak the stain with cold water
Use a sponge to soak any remaining blood-stained area of the jeans. Dab the sponge in cold water so that the stain does not become permanent.
- Apply salt
Apply a thin layer of table salt to the water-soaked area.
- Scrub the stain
Scrub the salt into the stain with an old tooth brush. Rinse the brush with cold water, as needed.
- Rinse the stained area
Rinse away all of the salt with cold water.
- Launder the jeans
Wash the jeans in a washing machine using regular detergent.
