How to Remove Blood Stains

    The best way to remove a blood stain, especially fresh, is with saline (salt water). It is what the red blood cells survive in our body. The RBCs are filled with protein (high osmolality) and need to be in osmotic balance with their surrounding fluid. If exposed to water (low osmolality), the water will rush into the cells, bursting them. Ex.: one drop of blood will turn a toilet bowl red. I use about 2 tbs. of salt to a qt. of water and blot the stain out. When I was an orderly, I ruined many clothes using hyd. peroxide. As a surgeon, I’ve ruined none.

    Half a pint of blood inside and outside a new boot, dried for 5 days. Got it clean with hydrogen peroxide – used a whole large bottle, neat. Affects the color, so it was necessary to “treat” the other boot – so they match. :-)

    I usually just get the milk out of my fridge and soak the stain in milk, and you won’t have anymore problems in worrying about causing other things. :)

    Windex works. As us girls know, and it’s a fact of life, period stains happen to the best of us, and you don’t want to throw away a good pair of panties. Spray on some Windex, rub it a little and let it soak, and then toss them in the washer as usual, and the stain should be gone. Works for me! :)

    I just removed a large blood stain from my couch with a paste made from meat tenderizer. I had tried everything else the night before and was still left with a residual stain. The meat tenderizer left a slight residual whiteness that I was able to vacuum away.

    How do you remove dry blood stains from hospital linens? Is it OK to first soak it in salt water?

    I have used this time and time again and it always works… take equal parts of Dreft and Clorox 2, mix them together and apply to the stains – old or new. Let it sit (it may or may not foam reacting to the blood). Older stains let sit overnight. Wash as usual. Review the stain prior to putting in dryer. If it needs it, retreat. Keep at it and eventually it will remove the stain.
    I have used this on a silk blouse, and on badly stained sheets. If the fabric has a print, it can fade the print, so be judicious. I have used this on old stains and it has lifted them with a bit of time and patience. It has also worked on upholstery.

    Isn’t rubbing and scrubbing pretty much the same movement. You tell us to only dab and not scrub, but then you contradict and further instruct to rub, which would further bind the blood back into the fibers…correct.
    Soak it, then continue the dab process.

    Just tried the salt water suggestion above from Wm Ives and it is golden! Bloodstain successfully removed from a brand new couch cushion in just a few minutes by carefully blotting with salt water. No damage to the fabric at all. It’s like it never happened: phew! Thanks Wm Ives!

    The meat tenderizer will help since, in my case, the stain was tried overnight with soap and a wet washing rack. It seemed the stain was washed, only to find that when the seat dried, it started to show again. Now, the stain is as dry as a nut and I don’t know what to do. I will have to try the meat tenderizer.

    I soaked some old bloodstains in cold water, rubbed with Seventh Generation laundry detergent, rubbed in some common salt, and laundered in cold water. This worked like a charm- thanks for all the great ideas.

    My blood was dry so it was really hard to get out, but I scrubbed and scrubbed and I put table salt and wipes on the stain. It started to come out, I just needed more salt and wipes…

    Just used vinegar and Dr. Bronners to get some blood stains out of my sheets. Worked like a charm!
