Assuming use of white or yellow carpenter's glue; IMMEDIATELY strip, apply
one of the commercially available pre-wash stain removers (Spray n' Wash,
etc), rub the cleaner into the glue area, let it set for a few minutes,
reapply and wash with normal detergent.

Did this last week with a shirt and it came out clean.
