Wow that all sounds so complicated.
I have a chronic illness so lots of heavy duty cleaning is hard for me, so I do this instead:
I arrange the perches so that none of them overlap in a way that would get poop on any of them
I use a homemade antibacterial spray that doesn't need to be wiped up. The spray is made from vodka and steeped peppermint leaves. The alcohol kills any and all bacteria but quickly evaporates, leaving a nice clean peppermint smell. Alcohol is nice in that even with heavy spraying it completely evaporates within 20 minutes and leaves no residue. I just take the birds out of their cages and spray down both cages completely once in a while. The mint tea/alcohol mixture is also really good at dissolving poop! Especially if you let it sit for five minutes before wiping it up, for dried on poops.
I use a cage with a deep bottom and use almond shell litter instead of cage papers. The almond shell isn't nearly as dusty as most litters and smells nice, and it quickly dehydrates any and all droppings so that nothing can grow in them. I clean this once a month using a bark scooper in a similar manner to how one would clean kitty litter. Once a year I take it all out and bake it on 200 degrees for half an hour just in case some insect or other decided it liked the almond litter. Makes my kitchen smell like wood smoke.
I also hose down the cages outside once a year while the litter is being baked.
