--I'm taking a whack at box making; last night I left something
gluing up with a square in place to make sure it cured to an accurate angle.
But I'd sponged the joint first, so some moisture got trapped under the foot
of the square and by morning there was a nice black stain there. Sooo aside
from sanding the crap out of it is there a way to remove the stain?

Iron stains come out with oxalic acid (sold as wood bleach or
wood cleaner); it is slow to act, and needs to be kept damp,
so I usually wad a bit of paper towel up and saturate it with
oxalic/water solution. Leave on the spot overnight, then
rinse and give it a day or two to dry.

muriatic (swimming pool) acid works also.

make yourself a set of assembly squares from plywood. drill large
holes in them to accommodate a clamp or 2. wrap the edges in clear
packing tape.

Probably not, but you could start with oxalic acid. Barkeeper's Friend
is a good source, or even a Stain Devil for cloth (you want the
bloodstains version, sometimes the inkstains version works too)
Don't breath the Oxalic acid sanding dust after drying.
