Cleaning blood and hair off of nylon?

[DireWolf]

Be curious to hear how this goes...

I have a BMF which ended up with the handle/grip (not really sure what it's made of, but is porous) completely soaked with blood (same cause) and only time for a quick-rinse then. Was never able to get it fully cleaned out, and not sure it's worth the risk of sending in for sevice (though that would be more related to blade refinishing than blood-soaked grip)
