When I dry fit the pieces, I'll wipe on a coat of paste wax (some can of
Minwax I've had for a decade) around the joints. Does not take very long
and makes glue removal a snap. As I almost always use a tung/poly or
linseed/poly mix for finish the wax does not interfere with the finish.

What's the best way to clean up some glue (e.g. Titebond II) that gets
on the surface of wood, such as oak? Will a damp rag be good enough? I
recently put some stain on some oak, and some areas containing residual
glue marred the finish.
