Clean the cage feeding pots, perches, drinking bowls and toys in a specially diluted solution of disinfectant once a week. After cleaning, rinse everything in clean water and dry thoroughly before returning the parts to the cage. All of the utensils you use to clean your bird's cage should be disinfected after each cleaning and used only for this purpose.
You should also renew the sand sheet or lay new sand on the cage floor daily if possible.
Of course, your bird should have fresh water and a fresh seed supply each day as well.
Talk to your breeder or supplier about appropriate cleaning solutions.
