What is the science behind blood stains and fabric?

98 views

I got a nosebleed a few days ago and was unfortunate enough to have been wearing one of my only white shirts when it did. After a full wash, there were still stains on my shirt. I expected it, as it has happened before, but now I’m curious. What makes blood stains so difficult to clean up and remove? (I googled this, but my 5 year old brain needs an answer a 5 year old would understand)

Blood has protein. Think like an egg.

Adding heat will scramble the egg (change the way the protein is folded).

I think.

Next time try peroxide or even dawn dish soap, cold water always because blood ‘sets’ like eggs do when exposed to heat
