Derek, I use a slightly dull chisel because I know of any better method. I’m afraid your box will be flocked.

I sometimes use a sharp knife or even a razor blade to carefully cut/scrape the glue out, especially if I cannot get a chisel in there.

Chisel from both of the sides (going with the grain) into the corner. Move up the joint for each stroke.
Light taps.
Clean up with sandpaper.

I would try softening it. Some options are denatured alcohol, acetone and vinegar. Try putting tape wherever you need to form a dam and lay a small puddle down so the glue is submerged. It’s hard to say how long it might take, but I’d check it after five minutes or so to gauge the progress. Hopefully it will eventually come away cleanly with a light pass with a chisel.

Trick I was shown, when doing final assembly to test clamp, rub down joints with a finishing wax.
( I use Chapmans ) then when glue is setting, after 30 min or so, just peel excess glue out, even after a couple of hours glue will peel out quite easily. To remove wax a quick rub with DNA or Shellac if that is what the finish will be
then apply whatever finish you want.

I’ve been able to take glue off with a plastic putty knife before. It doesn’t scratch the surface, although it can some indents, which aren’t normally noticeable, especially in a corner.

I use Andre’s idea with great success. Of course these are pre-dry/pre-glueup tricks. Another is to cut a coffee stirrer straw off at an angle and use it to scoop up the semi dried glue.

Not much help on this box but if you were using hide glue, either hot or liquid, you would not be asking this question. It cleans up with water and does not block finish like pva.
