Biokleen Bac-Out is a liquid enzyme cleaner built around live cultures that break down stains and odors rather than just masking them. It is aimed at pet messes, kid accidents, laundry, furniture and carpet, and the citrus-lime scent keeps it from smelling like a harsh chemical cleaner. The 128 oz bottle suits households that clean up messes often, and it competes with enzyme sprays like Nature's Miracle and Rocco & Roxie on the same plant-based, pet-safe positioning. Buyers rate it well overall, though some find the enzyme action slower than expected on old or set-in stains.

Owners rate Bac-Out highly, especially for pet accidents and laundry odors. Many say it removes smells at the source rather than covering them, while some note it needs time to work and can leave residue on carpet.
Biokleen Bac-Out is an enzyme stain and odor remover made from a blend of plant-powered substances. It uses live enzyme cultures to remove tough stains and odors. It can be used on clothes, laundry, pet stains, furniture, carpet and rugs.
The live enzyme cultures break stains and odors down into tiny particles. The smaller particles are easier for the formula's good bacteria to consume. The bacteria digest the stain and odor particles into carbon dioxide. They keep multiplying and working as long as soil, their food source, is present, so the formula continues to clean the stain and odor.
