In *cold* water and with a little bit of gentle agitation almost all
the blood will come out. I then rub a bar of "Vanish" over the area,
work in and cold wash.

A hot wash cooks the proteins into the fabric, and makes them pretty
much impossible to get out.

Yep, 60 C wash will most likely have done that. I think the
mechanisum is that the red cells rupture, the heat breaks down the
heamaglobin releasing the iron they contain and you end up with an
iron stain (aka rust).

As a last resort, you could try bleach applied directly to the spots
followed by a cold wash.

Might work but given that a cooked blood stain is principly a metalic
one I'd not be very confident.
