The best thing that I have found for decals, apart from the use of Microset and Microsol, is not soaking them in water at all. Instead, now I have a small box about two inches tall in which I have placed a thick piece of foam (could be slimmer but that is what I had) and filled the box in water so that the foam is completely damp. Then I just lay the decals on the foam until they can be used regularly. You might call it a wet palette for decals if you want...
