To remove blood from sheets, rinse the bedding in large amounts of cold water, wash the sheet with shampoo, soak the stain in cold water and an enzymatic cleaner, scrub the stain, and apply a mixture of hydrogen peroxide and ammonia. Once you remove the stain, launder the sheet.
- Rinse the sheet
As soon as you discover the stain, remove the sheet from the bed, and rinse the bloodstain in cold water. Do not use warm or hot water, since those temperatures set the stain.
- Wash with shampoo
Apply shampoo to the stain, and scrub it. Rinse the shampoo from the sheet, and check for removal of the stain.
- Soak in cold water
Fill the washing machine with cold water. Mix in an enzymatic cleaner, and allow the sheet to soak a minimum of 15 minutes. If the stain is old, let it soak longer. Scrub the stain by hand, or allow the sheet to agitate in the machine. Turn the machine to the spin cycle to remove the water from the sheet. Repeat this process several times until the stain is not getting any lighter.
- Apply hydrogen peroxide and ammonia
Mix a few drops of household ammonia in 3 percent hydrogen peroxide, and apply it to the stain. Rinse the solution from the sheet after three minutes, and repeat until the stain is gone.
- Launder the sheet
Place the sheet in the washing machine, and run it through a normal wash cycle.
