Biokleen Bac-Out Pet Stain Remover Spray & Gallon Refill - Enzymatic

In this review the Biokleen Bac-Out Pet Stain Remover is evaluated as a practical solution for pet owners who need a plant-based, enzymatic cleaner that targets organic messes. The bottom line: it is best for households with dogs or cats where vomit, urine, blood, drool or feces stains recur, because its live enzyme cultures and plant-based surfactants actively break down organic matter rather than just masking odors. The reviewer found the spray useful for quick cleanups and the gallon refill convenient for heavy use, with a mild lavender-lime scent that is safe for most surfaces.

Key Features

• Bio-active enzymatic formula: Live Bacillus cultures break down and absorb organic material so stains and odors are removed at the source rather than temporarily covered up.
• Multi-surface use: Safe to use on carpets, couches, collars, kennels, pillows, bedding and even mattresses, making it a versatile choice for whole-home pet cleanup.
• Plant-based ingredients: Uses plant-derived surfactants and no phosphates, chlorine, ammonia or brighteners to reduce harsh chemical residue on fabrics and floors.
• Ready to use foam spray: The foamer treats surface-level accidents without diluting, so you can spray and let enzymes work without mixing solutions.
• Pleasant natural scent: A lavender and citrus blend leaves a fresh, mild fragrance that helps neutralize odors while staying safe for dogs and cats.

Who It's For

Pet owners with indoor dogs or cats who face frequent accidents will appreciate this product, especially those who prefer eco-friendly, plant-based cleaners and want an enzymatic approach that targets organic stains and odors. The gallon refill suits busy households, breeders, rescue centers, or anyone who prefers to refill spray bottles rather than buying single-use plastics.

Those who need a disinfectant for medical-grade sanitizing, or who require a fragrance-free product for extremely sensitive pets, may want to consider a different product designed specifically for disinfection or an unscented enzymatic formula, since Bac-Out includes a natural lavender-citrus scent.
