I'm not sure if their is a scientific theory on the matter but if you think about what is really happening during the shedding process it makes a bit more sense. During the blue phase of a snakes shed cycle there is a fluid that builds up between the old skin and the new skin which is what makes the snake look so discolored during this time. Once the new skin has been successfully separated from the old skin the snakes colors go back to normal as it approaches the time it's going to slough off the old skin. I believe that soaking your snake during this blue phase interrupts the separating of the old skin from the new causing a bad patchy shed or even a completely stuck shed because the fluid that separates the skin was washed away. When my first snake was younger I used to soak him when he started to show signs of going into shed and most of the time he would have bad flakey sheds that I needed to help him remove but sometimes he would have a nice clean shed. I no longer soak any of my snakes. I just mist and provide the proper humidity range and they shed perfectly.You could possibly soak your snake after the blue phase and maybe it would result in a clean shed. But I would rather not stress my snakes out with a soak when they are already stressed by the shedding process itself. I'd rather just leave them be until they have completed the shed. I hope this is helpful and makes things a little more clear. I know it's hard to find good accurate info on certain bp matters sometimes.
