viewtopic.php?f=24&t=11578&p=78494&sid=b989a1f580da53c8ce995c3fd2d2eb77#p78494For general cleansing I usually use water, poop off, or stabilized chlorine dioxide (Oxyfresh) solution. My primary method of sanitation (following cleansing) is stabilized chlorine dioxide. Please read the post for more detail concerning chemicals and methodology.
I think I did not address it in the abovementioned post - my method for perch cleaning is that I have an iron shaped scrub brush with a handle that is ONLY used for perch cleaning and sanitation. I run the perches under hot water for initial treatment. Then I spray the brush with Oxyfresh solution (described in my other post) and foam it with a quick pass under the running water. Then I scrub the perches to clean debris from them. I rinse the perches and set them aside. Then I rinse clean the scrub brush and reapply the Oxyfresh solution. Then I do another scrubbing and rinsing session with each perch to sanitize it. The perches are placed on a table on fresh paper towels to air dry.
For toys I either soak them in oxyfresh and then scrub clean as described above or I spray with poop off, rinse clean, and then disinfect/sanitize with oxyfresh and rinse as described above.
My canary and parrots have separate brushes that I replace regularly JUST for their usage. This is to ensure that germs and food particles that are toxic to birds but not humans do not transfer themselves from my dish sponges. The canary and conures have separate brushes to ensure that they do not risk infecting each other as the different families of avians do have different kinds of bacterium et al that are harmful and helpful to them.
For very small toys or items with nooks and crannies like boxes, I buy soft bristle toothbrushes (the softest bristles will not scratch the plastic - leaving places for bacteria to hide). In my area Target sells boxes of soft bristle toothbrushes with pictures of Snoopy on them for under a dollar so I just keep a supply of those and change them once a month or so.
