These methods can be used on bird baths made of most standard materials like concrete, terracotta, plastic, and ceramic-glazed baths.

Discover some of the best ways to clean a bird bath and learn how to keep birds happy and healthy!

Easy Ways to Clean a Concrete or Other Type of Bird Bath

The methods listed below work on both concrete and most typical types of bird baths. The first thing to do before cleaning a concrete bird bath is to remove the water it's filled with. You can then choose which option you prefer to clean it, whether you use simple, natural methods or want to use something stronger for a deeper clean. Assess the area to decide the best way for you. Choose a technique based on how dirty the area has become, whether there are stains that need treating, and what process you feel most comfortable using. The safest approaches include water, vinegar, and baking soda.

How to Keep a Bird Bath Clean Naturally With Water

A cleanser isn't needed for the majority of bird bath cleanings as long as you regularly clean it. According to The National Wildlife Federation (NWF), you can clean a bird bath with just water and a stiff bristle brush. Another option is to use a power washer with water and a jet nozzle, which is a fast, safe cleaning process. The NWF also advises changing out the water on a regular basis to prevent the water from becoming stagnant, as this creates conditions for bacteria and algae to grow in your bird bath.

The National Audubon Society warns against using detergents to clean a bird bath. Science Direct explains that detergent can strip the bird's natural oils excreted from the preen gland (uropygial gland). The oils from this gland coat the feathers to provide antimicrobial protection from bacteria, ectoparasites, and fungi. The oil also waterproofs the feathers. When the oil is stripped from the feathers, the bird becomes vulnerable to these, and disease can set in.

How to Clean a Bird Bath With Vinegar

The National Audubon Society suggests using distilled white vinegar to clean a bird bath safely. This is a simple and safe method that won't harm birds or other wildlife. The recommended mix is 9:1 of water: distilled white vinegar. However, some birding organizations, such as Ottawa Valley Wild Bird Care Centre, report cleaning a bird bath with vinegar works best when using a 1:1 ratio of water and distilled white vinegar.
