My girls have had their Martins cage about 4 weeks now, and I just noticed how bad the urine build up was on the shelves. Bleck! I wipe the tiles down once/twice a day, and wipe the wire shelves down with a paper towel. I had not noticed the dry and crusty bits hanging to the bottom of the shelves. I took a scrub brush with plain water to it today to get away the build up. I didn't realize my girls were so gross

how do you guys go about cleaning the shelves in martins cages? Lets just say the girls made it a game of who could chew my fingers first, since I scrubbed the cage with them in it

And wheels:
My girls have a super pet wheel, but I find myself scrubbing it once a week, if not more. They get urine and feces built up so bad on it, its nasty O-o. Are silent spinners any better?
