To clean a bird cage, start by removing your bird to a safe location. Take out all toys, perches, and dishes from the cage. Dispose of any soiled bedding or paper liners. Use a bird-safe disinfectant to clean the cage bars, bottom tray, and any other surfaces. Rinse thoroughly and allow the cage to dry completely before putting back the clean bedding, toys, and dishes. Make sure to wash your hands thoroughly after cleaning the cage to avoid spreading germs.
