I would say clean everything like you would if the snake were currently living in it. There are professional non toxic cleaners out there, which are great, but most of us just use a 10% bleach solution and then rinse well. You can clean with a little dish soap if there is any nasty on the glass that needs a scrub. Then just disinfect with bleach.

I personally would feel more iffy about the wood just not knowing what it has been through. But I clean mine in the same 10% bleach solution and then rinse really really well. Some people bake them as well. I would do both with unfamiliar wood. It's probably fine though as long as it is good shape, not rotted or crumbling or moldy.
