How to dissolve white glue?

OK, I carefully cut the rails, soldered the joints, added so many feeders I’m considering farming, applied an awesome paint job to add the rusty rail effect, cut the drainage ditches, glued down the cork roadbed, sanded it for a perfect fit…

Then I glued down my track and made a MAJOR mistake. I carefully avoided gluing the points but managed to glue the heel of two switches.

I have been trying for weeks now to power wa***he affected area with a syringe and hot water and also tried an alcohol rinse. No good.

Does anyone have a suggestion on how I can fix this?

Take the piece off and boil it in a pot of water. Never done it though, it might work ,it might not. This is the only thing I can think for now.
