Probably A Dumb Question On Stuck Mint Stamps

Hello all. I have this huge envelope of mint stamps someone took poor care of and there are many blocks and larger sheets along with singles that have become stick together. Is there a way to get these apart without damaging the gum and the face of the other stamps, or if back to back can those be salvaged?

Or, as I have been thinking....the only way to get them apart and not damage the faces is by soaking them apart?

Some nice stamps in here and I would like to save as many as possible. Any help is appreciated.
