I use Formula H which is a concentrated liquid and you only need a tiny bit in some hot water, a little goes a long way. I don't wash the entire cage in it every clean, but do wipe the toilet corner, nest areas and wheels with it as Joey, and Rupert when I had him, peed in their wheels. It's also safe to use on food bowls etc too if rinsed well afterwards.

It's got a light scent but when heavily diluted you can't really smell much at all.
