So, I have a 4x2x18 tank in the upstairs of my house, using coconut fiber bedding, it wont be a little while until I have to do a full clean, but how do you guys go about doing yours?

I know how to sanitize all my decor and such, but the actual cage? Not entirely as I've read a couple mixed opinions and it's actually a little difficult to find what I'm looking for exactly.

So the main question I'm asking is, how do I sanitize the insides of an immobile cage?

At the nature center I volunteer at all their large cages are lifted by two people and carted to a cleaning room and cleaned by two people, but I'm just one person, its upstairs, and I don't have a convenient trolly that can do stairs
