I also use diluted vinegar to wipe down the cage. For that crusty urine build-up in the litter box, I just soak it with straight vinegar and it comes right off.
That's for cage and litter box cleaning. But I'm a bit concerned about the question on deodorizers. There should be no need for any deodorizers in or near a rabbit cage. (nor do I know of any that would be safe around rabbits) With a good litter box set up, there shouldn't really be any odor coming from the cage. I currently have 2 rabbits sharing a litter box and I only change it out every 3 days. I honestly have zero smell between then. Maybe you just need to make some adjustments to your set up?
