Reptile Wood

I have some driftwood that I'd like to use in my reptile cages (2 snakes, 2 bearded dragons). It was found outside, so I'd like to disinfect it first. I've heard something about using a bleach solution, but I can't recall the ratio of water to bleach. Is this safe for my animals? What is the procedure for cleaning with bleach? I've also heard something about baking reptile furniture in the oven to kill parasites and such. Would this be ok, since the furniture here is wood? I'm afraid they'll catch fire or something. What temperature should the oven be set on if I can do this? I really need to know the bleach technique or something else, though, since two of the driftwood pieces won't fit in my oven!
