Leak with Drywall and Wood Framing
It isn't going to cause mold or permanent issues to the drywall or wood.  That means there are basically two issues - aesthetics and cleanliness.  From a cleanliness aspect bleaching and normal cleaning is pretty par.  Crap can be hard to get out of lumber though.  If you have exposed wood framing and it has crap on it and it will remain exposed, they should replace it if you can see even the faintest trace.  Simply if you can see it, then it exists.  Meaning if there are brown marks, you can still touch crap particles.

From an aesthetics point of view everything should look exactly like it did before or better.  So the advice I am giving is set the expectations for them.  I don't care if they need to repaint, so be it.  They messed up (literally) and now have to fix it.
