How to Get Blood Out of Cotton Sheets

Blood stains on your cotton sheets may happen as a result of a nosebleed, accident or menstrual cycle. Blood stains are a type of protein stain. When protein stains are rinsed or washed in hot water, the hot water cooks the protein, causing it to become set into the fabric fibres. Use cold water and supplies around the home to remove blood stains from your cotton sheets. Tackle bloodstained cotton sheets as soon as possible for the easiest removal.

Dampen your cotton sheet at the site of the blood stain. Pour meat tenderizer over the blood stain, using enough to completely cover the stain. Let the meat tenderizer sit on the stain overnight.

Brush off the meat tenderizer into the garbage. Wet any remaining blood stain with hydrogen peroxide and allow the peroxide to sit on the blood stain and foam for 15 minutes. Rinse the bloodstained cotton sheet with cool water to flush the stain.

Pour enough liquid detergent onto the blood stain to cover it. Gently rub the fabric together to work the detergent into any remaining stain.

Wash your cotton sheet in warm water, not hot. In addition to adding the regular amount of washing powder, add one cup of white vinegar to the wash water. Vinegar is known to work well on tough blood stains and will also freshen the fabric.

Check to make sure the blood stain has been completely removed from the cotton sheet before you place it in the dryer. The heat from the dryer will set the stain.


Flush a fresh blood stain with cold water, right away, to remove as much of the stain as possible.


Avoid rubbing and scrubbing at a blood stain so you don't spread the stain.
