It will basically just look like cat poop is the best way I can describe it, different sizes depending on how much they've eaten since they last defecated. It shouldn't be slimy or loose...just typical firm stool. At least that's what my snakes always pass other than their urates.
I just usually scoop it out plus any bedding in the immediate area then just wipe with a cloth and hot water if there's any stool on the plastic, dry then replace bedding in that area only. About every 4 to 6 weeks I do a full disinfect of the cages. Just my routine, not the best way of course LOL.
Why are you wanting to soak her?
Also as far as whether the snake is using it's cool or warm hide, as long as your temps are correct the snake will move as it wants to back and forth. If your humidity is so high it is soaking your bedding however you need to address what is causing this. You don't want a snake on wet bedding as belly rot, etc. can occur plus warm + wet is a breeding ground for bacteria and mold.
