To disinfect a cage I wash the whole thing down with warm soapy water and get a soft brush on the bars otherwise its easy to miss stuff, you will need to do it outside if possible but if not cover everything up well because it does create a spray. This needs doing because disinfectant doesn't work effeciantly if there is any organic debris on the surface.
I allow the cage to dry fully before I disinfect, I don't think this is necessary but it makes me feel better to do so lol.
When I disinfect I spray the whole cage down from the inside and outside to try to avoid missing any areas. I let it dry and do it a second time just to be sure.
I'm only this thorough with second hand cages or if my birds are sick, usually its a quick wash with warm soapy water, get the worst of with a towel then disinfect.
It is important not to rinse the disinfectant off (if you need to) straight away, it needs time to work properly. I'm not sure what the minimum time to leave it on is, I would guess at about 20 mins but I usually wait an hour or so. Its like putting boiling water over something and calling it sterilized, usually it needs a minimum of 10-20 minutes constant boiling to be properly sterilized.
