How do you wash blood out of white clothes?

[BathshebaDarkstone]

DS hit his head at school yesterday, went to A & E and got it glued. I tried washing his polo shirt on a 40 degree wash, it's still looking kind of rust-coloured. Before it was washed it looked like he'd been beheaded, there was so much blood. He only has to wear it for 1 more half-term, they're bringing in proper shirts and ties in September. I suppose I could handle it looking grubby for a few more weeks, but has anyone got any tips for getting the blood out, preferably eco-friendly?

Put some hydrogen peroxide on it. Let it fizz then rinse in cold water (no hot water, it sets the stain). If the stain is large, repeat the process until completely gone

Put it on a hotter wash with a tiny bit of bleach on the worst parts but wash as soon as you put bleach on.

It might be too late now.

The truck is to soak it in cold water with something like vanish before washing it. Hot water sets the stain.

Soak it in Napisan - it works wonders.

It's no longer a stain, the whole shirt looks a bit grubby now. Will try Napisan. Thanks!

Yes for future accidents ( not that I would wish those on you) - no hot water it sets the blood a protein a bit like egg white in hot water it coagulates - also salt works rather well at getting rid of it no idea why !!

Hope you son mends soon

Thanks everyone.
