I wasn't so much considering it for cleaning as I was for sanitizing. I vaccum out substrate an replace it when I clean, so I'm dealing with an empty cage, hence no debris problem. I just figured it may be handy for cleaning cork, bowls and other cage furniture and flat surfaces as opposed to cooking (which much of my furniture is too large for) or using chemicals.

Really I just wanted to know if steam is hot enough to kill harmful bacteria and whatnot. That's all I need it to do.
