I am by no means an expert but I use simple soap and water to clean my BP's enclosure. I just use enough soap to get a bit of bubbles, wash it with a washcloth that is dedicated for use with the snake's various hides/bowls, then run warm water over it. When it comes to the tank itself, I have a glass aquarium so I use Windex then rinse with warm water.
Perhaps take whatever you washed with bleach and let it soak (if it is soakable) in a warm water/soap solution, then wash them clean with a washcloth and rinse them. See if the bleach smell is gone then.
