Hi there....
Oh my yes, tons of cleaning. I dont envy you. As for the bleach, I advise extreme caution, as snakes are so delicate and sensitive and can be burned if the bleach is the wrong proportions. I found Reptile Relief rather easy, and it is marketed as safe to use...at least, my five suffered no harm from it.
Oh, if you have more than one snake...treat them all, and their cages at the same time...else its possible they can reinfect each other. Mites can hitch rides on things and so travel.
Good luck again,
Sincerely,
Susan
