Rinse the stained area under cold running water as soon as possible to remove excess blood.
Blot the stain gently with a clean cloth or paper towel to absorb remaining moisture without rubbing.
Pour a small amount of hydrogen peroxide directly onto the blood stain to break it down.
Use a soft-bristled brush to gently scrub the area in circular motions to lift the stain.
Rinse the shirt thoroughly with cold water to remove hydrogen peroxide and loosened blood.
Apply a small amount of liquid laundry detergent directly onto the stain.
Let the detergent sit on the fabric for 5 to 10 minutes to penetrate the fibers.
Rinse the shirt again with cold water to remove the detergent and loosened stain.
Mix baking soda with a small amount of water to form a thick paste.
Apply the baking soda paste to the stained area and spread evenly.
Allow the paste to sit on the stain for at least 30 minutes to absorb remaining residue.
Rinse the shirt thoroughly with cold water to remove the paste and any remaining stain.
Check the stain; if it persists, repeat the hydrogen peroxide and detergent steps.
If needed, add a pinch of salt to the baking soda paste for extra scrubbing power.
Optionally, add a few drops of ammonia to cold water and dab the stain carefully in a ventilated area.
Once the stain is gone, launder the shirt in cold water using your regular detergent.
Avoid using hot water, as it can set any remaining blood into the fabric permanently.
Do not place the shirt in the dryer until the stain is completely gone to prevent setting.
Air dry the shirt by hanging it in a well-ventilated area out of direct sunlight.
Inspect the shirt after drying to ensure the stain has been fully removed.
