How do others clean their bird cages?

Didn't know where to post this. Nameliss has taken her disassemble to another stage. She's given up attacking the cage joints and joinings. Only checking locks randomly. She knows that the tray bottom slides out. After years of trying to remove it, gravity, physics and angles have caused her to give up. Now she's attempting to destroy it a chunk at a time. Fortunately she's not a Mac! So only a few scraps and minor bits missing. Nameliss works on random sections a few minutes. I have run out of ideas. I've been busy talking to neighbors. A construction engineer for suggestions. Between them neighbors have Amazon's and one a too nothing. I'm worried about plastic. I talked with the two avian vets at my office. Mine shrugged. The back up laughed. Complimented me on a successful bird proof cage. Now my birdie-vict is digging her way out. Nothing could be found so that I could remove tray for cleaning. Nothing could be thought of. Out of cage she still trying to pull it out. Often going outside to where she's chewing inside. It's driving me crazy. Any suggestions appreciated. I've spent days researching. If I take tray out the caster screws will be in beak reach.
