Why is it easier to wash bloodied clothes with cold water?
Maybe warm water helps the still not completely dry blood to stick to the surface? Also how does the salt help the cause? (red wine on a dinner tablecloth)
Edit: google says hot water will set the stain. Well, I knew that, what I want to know what exactly happens chemically that makes setting easier with warm water?

Because heat hardens proteins [denaturation] and makes them less soluble?
