You can pull the staples, cut or tear covers off or just tear off the stamps from the tab. Some just fold the cover back flatten and mount covers and stamps. For booklets with just one folded pane, those are merely opened and displayed cover and all.
But why? Except for C10a where the value of the two NH panes equals the value of the complete booklet with two panes, intact booklets are more valuable than when exploded.
Allow me a slight exaggeration but what you are saying is I have been given a sets of complete sheets of both the Columbians and Trans-Mississippi so what is the best way to remove the plate blocks for my plate block album.
Frankly, if you post trades, you could just trade the unexploded booklets for the one or two different panes contained within. Or, asking at you stamp club would work too.

Is there really a solvent for water-based adhesives that will work in general while leaving mint stamps completely untouched.

But sadly, you have only stumbled upon the secret wish of every collector of mint stamps, living or dead.

Edited for one "is" only.
