How do I remove a closet shelf that is flush against the closet wall with just a brace in the middle? The brace is not a problem, but the shelf looks like it's glued in. It has a 2 X 1(maybe) X 72 (closet length). And two small braces on each end about 2 ft in length X maybe 1" wide.
Most likely nailed from above into braces.
May be glued and/or caulked, so run a utility knife or window razor (single straight edge razor in a holder).
Then, as suggested by DA01 and Jacob S, wack upwards with a rubber mallet or a regular hammer into a block of wood
