you get him out very very carefully. I use a hook to get my adult male out when he destroys his cage. I tap him on the head, and if he's not feeling it I use the hook to pull him out and move him into a tub quick quick where he stays while I clean. They don't down right attack even during their bad days, they may strike out of the cage, but once they are out of the cage they will typically just try and take off on you. Fortunately my boy is not prone to too many days where he gives me any kind of "no", and my next biggest female purple is pretty much always receptive to coming out for a clean cage as long as its not a feeding day. On feeding days though, I have to use extreme caution if I need to move her, if its just urine and not too bad I'll let her cool down a hair and then open the cage and let her come out on her own. Just my ways.
