'Bathing' a snake is not necessary imho. I wouldn't worry about it too much, as the amount of poo will vary from snake to snake and depending on how much is food is being consumed. It's possible you are offering smaller meals that there isn't much 'waste' leftover to poo out. It also sounds like you may be using a wood chip bedding and may just be missing it.
I'd continue to feed regularly. (just curious about the size of the snake and the size prey being offered) If you notice a swelling toward the vent then you will want to take the issue more seriously. At that point you may want to soak the snake or even seek professional medical advice.
Otherwise just try not to worry to much. It all comes out in the end.![]()
