How to Clean Birdbaths


A birdbath is a welcome addition to your yard that can ensure that you will have a variety of feathered friends visiting you all season. Birds will not bathe or drink from a dirty birdbath that is filled with debris or algae, so it is important to clean birdbaths often. Household bleach will kill any bacteria growing in your birdbath, but oxygenated bleach is a better choice because it is non-toxic but has all the same benefits as regular bleach.

Step 1

Drain the birdbath of all water. Some birdbaths have a drain plug you can pull and others will need to be tipped over carefully to drain.

Step 2

Remove any large debris such as bark or twigs.

Step 3

Spray the birdbath out with a garden hose. If there is built-up gunk on the bottom, a high pressure spray nozzle on your hose will help dislodge it.

Step 4

Mix one part bleach to six parts water. Pour the solution into the birdbath and allow to sit for 15 minutes if there is extensive mildew or algae build-up. Scrub with a brush to help remove the grime.

Step 5

Rinse thoroughly with warm water. Birds are sensitive to cleansers so you must remove every trace. Refill the birdbath with clean water when done.

Tips and Warnings

  • Bleach is poisonous and can also kill grass, so rinse well and be careful where you pour it.
