Yes, it can be saved. I wash most of my birds with some diluted Hydrogen Peroxide, which will whiten just about everthing. Winks is another cleaner that people will use to wash out rust in white birds, like Snow Geese. I fleshed and washed a pintail yesterday, that was blood soaked, and I did not remove all the blood, which surprised me a bit, because it was the first time that I didn't remove all the blood. I will wash it again the day I go to mount it, to see if I remove the remainder of the blood.
