Well, I haven't had my snake very long and I've just been spot cleaning, but her breeder reccomended I soak everything in a 4% bleach solution every month.
I'd still leave him be for at least a week. Being patient is tough but you'll be rewarded. Like I said before, let him get acclimated and then attempt at feeding. Wait two or three days after he eats before handling. [If he doesn't eat, wait another week, and try again.]
