Blood stains on your mattress can happen when you wake up in the morning only to discover you've got your menstrual period during the night. While it's ideal to remove blood stains from your mattress while they're still wet, this isn't always a possibility. Removing dried blood stains may require more effort, but it's not impossible.
Dampen a sponge with cool water and squeeze out the excess moisture. Blot the dried blood stain on the mattress to add a little moisture back into the stain. Moisten the blood stain without saturating the mattress so the cleanser and stain remover is more effective.
Combine 1/2 cup cornstarch, 1 tbsp table salt and 1/4 cup hydrogen peroxide in a bowl. Stir the mixture well with a spoon to create a paste.
Smooth the peroxide paste over the moistened blood stain on your mattress with the back of the spoon. Leave the peroxide paste on the bloodstained mattress until it's fully dry. The dry ingredients and hydrogen peroxide work together to loosen and lift the dried blood stain.
Brush the dried peroxide paste off the mattress using a hand broom and dust pan. Apply another helping of paste to any remaining blood stain on the mattress, repeating Steps 3 and 4 until you've removed as much of the stain as possible.
Mix 1 tbsp household ammonia with 1 cup cool water in a bowl. Dip a clean cloth in the ammonia solution, then squeeze the excess moisture out. Dab the ammonia-dampened cloth on the remaining blood stain on the mattress, working from the outer area of the stain into the middle.
Pat the mattress dry with a clean, dry cloth. Allow the mattress to air dry completely before putting a sheet over the mattress.
A protective mattress pad keeps your mattress clean and safe from a variety of stains.
Avoid the temptation to scrub blood stains as this may cause the stain to spread further into the mattress.
