Yeah, I would give everything a good cleaning about once a month. You can use vinegar or diluted bleach solution (I've done a 10:1 solution of water:bleach when I'm out of cleaning stuff). Just make sure to rinse well and let dry before putting the snake and its stuff back in. And it shouldn't take too long to clean one enclosure that you have to worry about your snake getting RI. At a guess, my tubs take 15 minutes each, tops.
