If you’ve been dealing with pet accidents, wine spills, or years of ground-in dirt, you’ve probably tried a cleaner that either smells like a chemical plant or barely works. Biokleen takes a different approach — using live enzyme cultures and citrus extracts to actively break down organic material rather than just masking it.
As the Biokleen homepage puts it: “Death. Taxes. Spills on carpet. All three are impossible to avoid.” The question is what you clean them up with.
I’m marlen, and I’ve spent years researching eco-friendly home cleaning solutions — including hands-on testing of biokleen carpet cleaner products across multiple carpet types and stain scenarios. Read on for a full breakdown of whether it lives up to the hype.

The Science and Safety of Biokleen Carpet Cleaner
When we talk about “cleaning power,” most people think of harsh solvents that melt dirt away. However, we prefer a smarter, more biological approach. The magic behind biokleen carpet cleaner lies in its use of bio-enzymatic technology. Instead of using corrosive chemicals to strip away stains, Biokleen employs live enzyme cultures that essentially “eat” organic waste.
Think of these enzymes as tiny, microscopic workers. When you apply a product like Bac-Out to a pet stain, these live cultures produce enzymes that break down proteins, starches, and fats into tiny particles. They don’t just sit on the surface; they continue to work until the organic matter is completely gone. This is why Biokleen is so effective at removing the source of odors rather than just covering them up with a heavy perfume.
Understanding the Biokleen Carpet Cleaner Variants
We’ve found that many users get confused between the different bottles on the shelf. Here is the breakdown of the primary variants you’ll encounter:
- Bac-Out Carpet Stain & Odor Remover: This is the flagship bio-enzymatic formula. It’s a “live” product designed specifically for organic mishaps—think pet urine, vomit, wine, and food spills. It’s available in 32 oz sprays and 128 oz value jugs.
- Carpet Kleen Concentrate: This is the heavy lifter for large-scale cleaning. It’s formulated for machine use and is incredibly concentrated. A single 32 oz bottle can make up to 32 gallons of cleaning solution. It uses natural citrus oil to emulsify dirt and lift it from the fibers.
- Carpet Pre-Spotter: Designed for high-traffic areas, this product is meant to be applied before you start your full machine extraction. It penetrates deep into the carpet pile to suspend heavy soils.
- Bac-Out Foaming Spray: This version is excellent for vertical surfaces (like the side of a sofa) because the foam clings to the fabric, giving the enzymes more “dwell time” to do their job.

Certifications and Environmental Impact
We aren’t just taking the company’s word for it when they say they’re “green.” Biokleen has the credentials to back it up. A total of nine Biokleen products have earned the prestigious Green Seal Certification. Furthermore, many of their formulas are U.S. EPA Safer Choice Certified, meaning every ingredient has been vetted by scientists to ensure it meets strict safety criteria for human health and the environment.
The products are biodegradable, ozone-safe, and non-aerosol. Perhaps most importantly for many of our readers, Biokleen is strictly cruelty-free and never tests on animals. This commitment to ethics earned them a spot in the Real Simple Green Cleaning Awards.
Performance Review: Removing Tough Stains and Odors
Does it actually work? That’s the $44 question. Based on our research and over 1,700 global ratings on Amazon, biokleen carpet cleaner maintains a solid 4.5 out of 5-star average. Users frequently report that it outperforms traditional chemical cleaners, especially when it comes to “rescuing” old carpets.
| Stain Type | Effectiveness | Best Product to Use |
|---|---|---|
| Pet Urine | Excellent | Bac-Out (Enzymatic) |
| Red Wine | High | Bac-Out or Pre-Spotter |
| Ground-in Dirt | High | Carpet Kleen (Machine) |
| Coffee/Tea | Moderate-High | Pre-Spotter + Machine |
| Grease/Oil | Moderate | Carpet Kleen (Citrus based) |
One of the most impressive statistics we found was from a long-term user who cleaned a 19-year-old carpet that was riddled with old residue from previous chemical cleaners. After using Carpet Kleen, they noted that old stains were reduced to 30% of their original size and the carpet pile felt restored and soft, rather than crunchy.

Tackling Tough Stains with Biokleen Carpet Cleaner
The real test of any cleaner is how it handles the “big three”: pets, kids, and parties.
1. Pet Mishaps: Cat vomit and dog urine are the ultimate tests. Because Bac-Out uses live cultures, it doesn’t just neutralize the scent for human noses; it removes the pheromones that lead pets back to the same spot. Professional cleaners on forums like Mikeysboard have noted that Bac-Out is a “magic” spotter for organic stains.
2. High Traffic Areas: We all have that one “pathway” from the kitchen to the living room that looks darker than the rest of the house. The citrus extracts in the biokleen carpet cleaner machine formula act as natural degreasers. They break the bond between the dirt and the carpet fiber, allowing your machine to suck up the “murky water” that many users find both gross and satisfying to see in their extraction tanks.
3. Old Residue: Many commercial cleaners leave behind a soapy residue. This residue actually acts like a magnet for new dirt, which is why your carpet seems to get dirty faster after a cheap cleaning. Biokleen is designed to be low-foaming and free of synthetic brighteners, meaning it rinses away cleanly.
Step-by-Step Guide: How to Use Biokleen Products
Using a natural cleaner requires a slightly different technique than the “spray and pray” method used with harsh chemicals. Enzymes need time and the right environment to work effectively.
The Golden Rules of Application:
- Dilution is Key: For the Carpet Kleen concentrate, the standard ratio is 1 oz of product per 1 gallon of water. Because it is so concentrated, using more won’t necessarily make it cleaner—it might just waste product.
- Temperature Matters: For optimum results, we recommend using water between 110°F and 115°F. This “warm but not boiling” range is the sweet spot for activating the citrus emulsifiers without killing the live enzymes in the Bac-Out variants.
- Dwell Time: If you are using the Carpet Pre-Spotter or Bac-Out on a specific stain, let it sit for 5 to 10 minutes. This allows the enzymes to begin the “digestion” process of the organic matter.
- Machine Compatibility: These products are safe for use in almost all home and rental machines, including Bissell, Hoover, and Rug Doctor. Because they are low-foaming, you don’t have to worry about bubbles overflowing your recovery tank.

Professional Tips for Maximum Extraction
We’ve gathered some “insider” tips from professional carpet cleaners who use Biokleen in the field:
- The Vacuum Prep: Never skip the dry vacuuming. Vacuum thoroughly in two directions to remove as much dry soil as possible before getting the carpet wet.
- Overlapping Strokes: When using a machine, use slow, overlapping strokes. One pass with the trigger pulled (wet) followed by two passes without the trigger (dry) to ensure maximum moisture extraction.
- The “Oxy” Boost: For extremely stubborn stains on light-colored carpets, some professionals boost their Biokleen solution with a small amount of sodium percarbonate (oxy-bleach).
- Natural Fiber Precautions: If you have wool or silk rugs, always test for colorfastness in an inconspicuous corner. For these delicate fibers, we recommend diluting the cleaner by an extra 50% to be safe.
Frequently Asked Questions about Biokleen
Is Biokleen safe for use around pets and children?
Yes! This is the primary reason many families switch to the brand. The plant-based formula contains no harsh fumes and is non-toxic. It is EPA Safer Choice certified, making it one of the safest options for households where little ones are crawling on the floor. It is also noted for being sinus-friendly and non-irritating to those with chemical sensitivities.
Can I use Biokleen in any carpet cleaning machine?
Absolutely. Whether you own a Hoover Smartwash, a Bissell ProHeat, or you’ve rented a machine from the grocery store, biokleen carpet cleaner is compatible. Its low-foaming nature prevents the “clogged jet” issues that plague many other “green” cleaners that use too much soap or powder.
How does the concentration compare to other brands?
Biokleen is significantly more concentrated than many competitors. While a standard bottle of a “big brand” cleaner might only do 2 or 3 rooms, a 32 oz bottle of Carpet Kleen makes 32 gallons of wash. This makes it an incredibly cost-effective choice for large homes or commercial spaces.
