A foamable aqueous cleaning composition for treating surfaces to dissolve grease and organic waste materials thereon. The foamable aqueous cleaning composition comprises a) about 40 to about 60 percent by weight water; b) about 40 to about 60 percent by weight of a bioremediation agent capable of breaking down organic contaminating material and capable of producing a desired number of colony forming units of microbes; c) optionally, an insect growth regulator; and d) about 7 to about 15 percent by weight of a compatible propellant. The foamable composition is aerosolized to release the foam composition and contacted with the surfaces to be treated. The foamable composition can be used to treat drains, baseboards, cracks, crevices and other similar surfaces, especially in food preparation areas.
