I wash my snakes aswell... Have you never had your snake slither through the big fresh mound of morning doo doo before?? LOL Its pretty nasty, and if you dont wash them off it stinks pretty bad.... Same with when a large boa or something similar pee's and your using newspaper substrate... The whole floor of the cage is soaked, the snake in laying in the pee and if you dont wash him off, it stinks aswell... So personally i know exactly where to skater is coming from!
