I know what you mean. Have you tried to trim it down to where most of the bad material is gone. You need to open it up so you can scrape out most of the bad stuff then spray it with diluted bleach. It is painful but it gets it done. I don't know if you have a handling area to be able to get it done. I haven't read enough of your posts to know what your situation is to be able to work your sheep.
