Keep bird baths, fountains, feeders, and birdhouses clean without bleach or copper—these natural enzyme formulas dissolve biofilm, algae, seed gunk, and droppings so water stays clearer and surfaces don’t get slimy. Safe for wild birds, pollinators, and plants when used as directed; non-foaming, low-residue, and unscented. Works on stone, metal, plastic, and wood. Use a quick weekly maintenance dose for baths/fountains and a deeper clean for feeders/birdhouses to cut odor and reduce buildup. Biodegradable and made in the USA.
