How to Clean a Concrete Bird Bath
- 1). Change the water in the bird bath every one to two days. Dump out the water, rinse with the garden hose and refill with clean water. This prevents the bath water from stagnating, thus providing a breeding ground for mosquito larvae and harmful bacteria.
- 2). Fill the bird bath with 1 part vinegar and 4 parts water when heavier buildup is present.
While many people use bleach to clean the bird baths, vinegar is a safe, chemical-free disinfectant and cleaning agent that won't harm the birds and surrounding vegetation. - 3). Let the vinegar and water stand for 15 minutes, and scrub with a nylon scrub brush.
- 4). Discard the vinegar water when all residue is scrubbed off of the concrete.
- 5). Fill the concrete bird bath with fresh water from the garden hose.
- 6). Drop a birdbath additive cleaner into the bird bath every 30 days, or as recommended on the brand you purchase. These come in liquid and tablet form, and reduce cloudiness, stains and residue buildup.
