You’ll first want to treat them right away, as it is a lot easier to clean up if you do not let it set in for several hours or even longer. Blood will dissolve easing in cold or cool water. Do not ever use hot water since it will literally cook the blood and you might not ever be able to get it out after that. With the cool water, you can use a dab of dish soap and gently rub it in with your fingers to break the blood up. Never use the dryer either, because the heat from it will set in any of the stains that might remain. Instead, air dry the sheet or lay it flat to dry.
Cleaning Fresh Blood Stains
If possible, fill a sink with cold water and put the stained sheet in it. While it is wet, scrub the stain with your knuckles or fingers to loosen as much of it as possible. If the stain is now gone, you can launder it right away and skip pre-treating it.
If there is still some blood after rinsing or soaking the stain, put one tablespoon of dishwashing liquid on the stain. Allow the detergent to work on the stain for fifteen to thirty minutes. The stain should now be gone or almost gone.
Now put the sheet in your washing machine with cold water and your detergent and launder as usual. This should eliminate the stain completely.
Stains that are Heavy Duty
If the stain still remains after this step, don’t fear. As long as heat has not been applied to it, you can still get it out, as is ammonia.
Hydrogen peroxide is usually recommended for getting out blood stains. It can be used full strength and put directly onto the stain. Ammonia, however, should be diluted with water first, using one tablespoon of ammonia to a cup of water, putting it on the stain and then washing it as soon as you can. Allow the solution to work on the stain for thirty to sixty minutes then you can wash it in cold water. If necessary, you can repeat this process.
Getting Rid of Old or Dried Blood Stains
You won’t always be to treat blood stains right away. This is true, especially with bedding. If this is your situation, you can soak the sheets in cold water for many hours to dissolve and loosen all the stain that you possibly can. You could even run it through a cold water wash along with a mild detergent. Then see how much stain is remaining and mix a tablespoon of meat tenderizer and to teaspoons of cold water to form a paste. Spread this paste on the stain and work it in with your fingers. Let it sit for thirty to sixty minutes and then shake off the excess before washing It in cold water.
