Empty the bird bath and scrub it with a brush. Rinse thoroughly with water to remove debris and dirt.
Mix a solution of water and white vinegar or mild dish soap. Scrub the bird bath again with this solution.
For disinfection, use a diluted bleach solution. Let it sit for a few minutes before rinsing thoroughly.
Scrub the edges and any hard-to-reach areas to ensure all surfaces are clean and disinfected properly.
Rinse the bird bath with clean water again to remove any remaining cleaning solution. Allow it to air dry completely.
Refill the bird bath with fresh water and place it back in your garden for your feathered friends to enjoy!
