Water bowls are run through the dishwasher, but then, I have stacks of spares because several of my snakes like to use them as toilets.
Plastic hides also do ok in the dishwasher. If you're using wood hides you'll have to toss them, they're almost impossible to treat and disinfect. You don't have to get pricey pet store ones either, I've converted a lot of the plastic restaurant or frozen food containers into serviceable hides.
