Do you mean a spray you can use INSIDE the snake's enclosure? If that's the case, I don't know of any, and i don''t recommand spraying any kind of chemical inside your snake's enclosure or on anything that your snake would come in contact with.
Some people freeze their snake's bedding(without the snake of course!) to kill off some bacteria and mites.
If you want to clean off the things inside the enclosure such as water bowl and rocks and such, just soak in very diluted bleach water and rinse thorougly with hot water to get rid of any bleach left on them.
I don't think the substrate really needs to be cleaned daily, just spot clean to get rid of poop. If it becomes dirty, just replace it with clean, new substrate.
