I pulled out a fleece to wash yesterday and discovered it has yolk *sigh* Big bright yellow spots. I will have to wait for it to dry to see how much of it I need to toss. Otherwise it was a decent fleece. Unfortunately there was no way to tell with this particular faded moorit fleece before I washed it. At least it's not one of my good fleeces, and I was only going to use it for dyeing in the lock.
