With the amidol situation as it is, it sounds like there might be a couple of things to do in general. Since it is mixed once per session, these precautions might be in order and I guess I'll be doing them each time I use some. Anyone care to add to this list of remedies?

First : strain the developer once it is mixed, coffee filter, paper towel, napkin or whatever seems to be fairly fine, easy and cheap to use
Second: take an unexposed sheet of sacrificial paper (cheap again, not first quality) and dunk it in the developer for a couple of minutes, then toss
Third: make prints
