My friends, the secret to saving your garments (and bedsheets) is hydrogen peroxide.
It works by breaking down the hemoglobin in the blood, which lets it wash out of the fabric. Just apply generously and let it foam and sit for about 10 minutes. Rinse thoroughly with cold water. If the stain is still very visible, do it again. (Twice should be enough, but I did have some bike shorts i had to treat thrice.) Wash in cold water with your usual detergent. Check to be sure the blood all came out, and if not peroxide again! If it's out, dry as usual.
Works on blood from cuts, scrapes, bloody noses & other injuries, too. Clothes are expensive enough, don't let a little blood destroy them.
Adding on, if my friend here doesn't mind.
DAWN. Or the store brand that is closest to the blue original dawn. I have found that if something wants to be discolored even after the hydrogen peroxide, Dawn or its knock-offs will get the discoloration.
Also, COLD water NOT hot water
