I bought about 30 stainless steel dishes at a restaurant supply place and my dishwasher is always going , I don't know how you do it without one.
I have to have the bottoms of the cages where they can't get to it ,they run around trying to scrounge each other's leftovers from the night before I get the new egg crates in them. Nice thing about having a Resturant is a never ending supply of egg flats you can fit them in like a puzzle and take that piece out when dirty then the housekeeper pulls the cages apart 3 times a week and disinfects. {I'd die without her }these cages are huge and you have to climb inside some of them.
(she's young) besides my birds are piggys and always packing food ,wood whatever will fit in there mouths around the house.
