Use it on porous surfaces such as carpet, rugs, pet bedding, upholstery, clothing and more. This formula contains safe bacteria that penetrate surfaces to break down and digest soils. Simple Green Bio Dog can be used as a spot cleaner, in carpet cleaning machines and as a laundry pre-treat on new, old and set-in stains. The stain and odor remover discourages revisiting and remarking and leaves behind a pleasant, fresh scent.
