Carefree Birdbath Protector was developed in 1995 exclusively to help my grandfather keep his birdbath clean. For years, my grandfather would scrub for countless days and hours using bleach and cleansers until his knuckles bled. Wanting to help grandpa is what brought this product into action and CareFree Birdbath Protector was on the market. Bacteria Free, Non-Toxic. Safe for Birds, Pets and Wildlife. Patrick Haley Happy Birding!
