If you are just using water, try adding a drop of unscented, uncolored dish detergent to the bath. Use luke warm water. It helps speed up the process, but do not use hot water. Many gums are based on animal fat. Be careful of aniline inks as they will dissolve in water.
After soaking (cold, hot, warm or whatever) I place the wet stamp on a piece of flat glass and GENTLY scrape the soft goop off with the straight, flat edge of an old credit card.

I once obtained (I can't imagine buying them!) a short set of the Spanish Columbian tribute issue of 1930. The stamps were curled into tight little tubes. Soaking did no good at all. Soaking with warm then hot water did no good at all. Soaking and rubbing with my fingers did no good at all. Then I went to the last resort.
After thoroughly soaking them in warm water, I laid them one at a time face down on the wet palm of my hand. Using a very sharp paring knife, with the edge held at right angles to the stamp I scraped them gently from the centre to beyond the perfs in all directions, again and again, pausing every few strokes to clean the gum, which was still sticky, off the knife blade. When I could see no more gum building up on the knife blade, I gave them another a good rinse and dried them. They're flat as a filbert. Flatter, even.

Gum worshippers should pass on this...... so the worst of the worst in my opinion. French Colonies, Russia,and most eastern bloc countries,some Spain, I know there others. Any surefire one and done soak to remove the foul stamp curling goo ? Floating some of these stamps with structural rated adhesive that could qualify for a 500 plf shear wall is a challenge, so any tips that will speed the process ?
I have tried the hot soak, warm soak, cold soak, lick and stick to paper, then soak and repeat but I usually end up scrubbing the backs to remove the slime. And no, I really do not lick and stick, but apply water to the stamp. I prefer gumless stamps that lay flat rather than curled stamps with gum.
Feel free to add any nasty gum issuers.
