Don't know what you mean by "edge glued"...solid birch? The gumminess
comes from
grease softening the finish. Methylene stripper is strongest, fastest,
but you have a lot of
doors. I did a smaller kitchen with oak cab, which turned out
beautiful. You would
need to take doors drawers outdoors because it is stinky, messy work.
I've done a lot of
furniture, never used the citric strippers. Methylene semi-paste x2
applications, stcrape,
clean up with steel wool and mineral spirits. Much quicker if the doors
have no moldings.
