Biokleen Bac-Out Stain + Odor Remover

Bac-Out’s live enzyme-producing cultures attack pet, food and beverage stains, organic waste, and odors until they are gone, digesting them back to nature, safely and naturally. Bac-Out is safe to use around children and pets, even birds.

Great for stain and odor prevention with cloth diapers!

Bac-Out makes use of the power of lime peel extract! Odors be gone! We use this in our Diaper Service delivery vehicle just to be sure there are no lingering odors from the hundreds of stinky diapers we collect weekly. It's also great for mold and mildew. 

Do you have extra sensitive skin and/or chemical sensitivities? We've found that Bac-Out works well for those who do, meaning it doesn't cause any flare ups or irritation!


Choose from 32 oz. foaming spray (the spray bottle is our preferred method of applying Bac-Out to cloth diapers or other stains/fabrics ) or 128 oz. (for refilling your spray bottles or using in other way).


Natural enzyme-producing cultures, food-grade lime extracts and stabilizers, vegetable-based surfactants and filtered water.

No phosphate, chlorine, ammonia, petroleum solvents, alcohol, butyl, glycol ether, SLS or SLES, EDTA or DEA.

Not tested on animals and contains no animal ingredients.


Why choose Biokleen?

Biokleen has been perfecting their cleaning product formulas for over 20 years. All of our products are concentrated, which means less energy in shipping, less waste and more value for you!

Do any of the Biokleen products contain chlorine bleach, optical brighteners, phosphates, or Sodium Laurel/Laureth Sulfates (SLS/SLES’s)? 
All Biokleen products are free of chlorine, optical brighteners, phosphates and SLS/SLES ingredients.

What is a Surfactant?
Surfactants are conditioners that reduce the surface tension of water, allowing a surface to wet quickly so soil can be loosened and removed. The surfactants used in Biokleen products are vegetable-based—we do NOT use Sodium Laurel or Sodium Laureth Sulfate surfactants (SLS/SLES).

What is Linear Sulfonate?
Linear Sulfonate is a propriety blend of vegetable based surfactants.

Are Biokleen products safe for people with allergies and chemical sensitivities?
Yes, Biokleen products are highly recommended because we use the safest, highest quality ingredients without using common allergens, asthmagens, synthetic fragrances, and artificial dies.  The Free & Clear Products are recommended for those who prefer unscented products to those products that contain even natural fragrances.

Do any Biokleen products contain gluten, dairy or nut ingredients?
All Biokleen products are gluten-free, dairy-free and, aside from coconut-based surfactants, do not contain any nut-based ingredients.

Does Biokleen test any of the products on animals or contain any animal-based ingredients?
No. As a matter of fact, People for the Ethical Treatment of Animals (PETA) include Biokleen in their approved products listing!

Is Biokleen safe to use in septic systems? 
Yes! Biokleen products do not contain any Chlorine Bleach, or Phosphates or other harmful elements that would damage septic systems.

Is Biokleen’s packaging recyclable?
Yes! Biokleen packages their products using recycled material wherever possible. Check with your local recycling agency to see what they currently accept. If they need to expand their recycling capabilities, by all means start a community effort to initiate needed changes!

Do I need to dilute the Bac-Out Stain & Odor Eliminator before using this product? 
Whether or not the Bac-Out needs to be diluted really depends on what it’s being used for. It is concentrated; meaning a small amount of product can be very effective. In most cases, it is used full-strength; this includes treating organic stains on laundry and carpet, cleaning sink/bathtub drains and garbage disposals, and treating other targeted cleaning issues. For projects where diluting might be more appropriate (such as general deodorizing, supplemental cleaning in the bathroom or kitchen, diaper soak pails, etc.) add ¼ cup of Bac-Out to each gallon of water.

Is Bac-Out Stain & Odor Eliminator safe to use on wool rugs?
Yes! However, as with any fabric, check for colorfastness.
