So how do I get blood out of jeans?

[tmmiibaja]

The blood marks are just ricochet, maybe 5"x3" each, and there are 2 of them. I really like how these jeans fit, and would like to keep them, without the stains. Is it possible?

Is it also possible to remove all DNA remnants?

I am not a specialist on detergents and soaps but here
is my understanding of this:
The compound of a blood stain that causes the coloring
is iron, bound in a protein called hemoglobin. It is
this protein that gives blood its red color, and the
iron ions captured in hemoglobin transport oxygen in
our blood.
When blood dries up on cloth material, the protein
becomes denatured (is no longer in the biologically
active form) and binds to the material fibres. The
iron (no longer bright red but ironish brown) is
captured in this protein. Heating (hot washing)
fixates the protein even stronger to the tissue. It
can not be removed with normal soap which removes
grease and fat, but poorly removes protein.
Proteases degrade the protein into small bits that
come loose, and then the iron ions (the color of the
stain) are released.
Lipases degrade fat and amylases degrade
polysachharides, both would be useless to remove
hemoglobin.

In otherwords try Hydrogen Peroxide or Ammonia in a small unseen area. Hydrogen Peroxide normally destories the DNA too!

But wont it bleach them?

Kinda though you were joking. Really try hair shampoo in cold water...do not use hot water as the heoglobin will have added bonding strength.

Things like Oxy clean (oxygen beach, usually color safe) and Ammonia will work well if the Shampoo does not work.

Better check with CSI Miami. Delco may be able to help. :)

If you make a small amount of paste out of dishwasher soap and rub it in there, that usually works. Just don't use too much or it will lighten the color
