For daily cleaning, gently mist your bird from a spray bottle or by lightly sprinkling him with the spray attachment of a garden hose. A bathroom shower or the spray handle of a kitchen sink also works very well. For more thorough cleaning, plain baby shampoo works best. Add a tablespoon of baby shampoo to a pint of water. Spray the bird lightly with the solution until the plumage is completely wet. Let the bird sit in a warm place for five minutes or so, then rinse him thoroughly with clear water.
