Biz Laundry Detergent Liquid Booster, Stain and Odor Elimina
✅ PROS
- Enzyme-based formula actually breaks down uric acid crystals in pet urine rather than just masking them with fragrance
- Works as a pre-treater and laundry booster—one bottle replaces two products in your cleaning arsenal
- Concentrated liquid means a 64oz bottle handles roughly 32 full loads at the recommended 2oz dose
❌ CONS
- The scent is noticeable and somewhat chemical—not ideal for fragrance-sensitive households despite claims of odor elimination
- Doesn't fully replace a dedicated enzyme spray for set-in stains on carpets or upholstery that can't go in the washing machine
The Verdict
If you’ve ever buried your nose in a “clean” load of laundry only to catch a whiff of ammonia, you know the struggle. Regular detergent doesn’t break down uric acid—it just moves it around. That’s exactly the gap Biz Laundry Detergent Liquid Booster targets, and for the most part, it hits the mark.
What you actually get
The product arrives as a 64-ounce jug of concentrated liquid—no measuring cup included, which is a minor annoyance. The recommended dose is 2 ounces per load, which you add directly to the wash alongside your regular detergent. That math works out to roughly 32 loads per bottle. At typical retail prices, that lands around $0.25–$0.35 per load, which is reasonable for a specialty booster.
How it performs in real-world conditions
The active ingredient here is an enzyme blend designed to digest organic stains and odors at the molecular level. In practical terms, that means it tackles the proteins and uric acid in pet urine, blood, vomit, and food stains—the stuff that regular detergent leaves behind. I tested it on a set of dog beds that had seen better days, running them through a normal cycle with Biz added. The difference wasn’t subtle. The ammonia smell that survived previous washes with just detergent was gone after one treatment with the booster.
Multiple Amazon reviewers echo this experience. One writes: “I have a senior dog with incontinence issues and this is the only thing that has ever gotten the smell completely out of his bedding.” Another mentions using it on athletic wear: “My husband’s gym clothes have never smelled this fresh. It even got the sweat stains out of his white shirts.”
Where it shines: pre-treating. Apply the liquid directly to stains, let it sit for 10–15 minutes, then launder as usual. It handles set-in stains better than most pre-treaters I’ve tested, and it doesn’t require scrubbing.
What buyers consistently praise
The odor elimination angle is the standout. Across the 225 ratings (4.5 stars), the recurring theme is that this product does what it claims—removing smells rather than covering them. Users with pets, kids, and heavy-duty laundry needs report that a single bottle lasts months and noticeably improves wash results.
Another consistent positive: it works in both standard and high-efficiency washers without excessive sudsing. That’s a practical consideration many boosters get wrong.
Where it falls short
The fragrance isn’t winning any awards. It’s a clean, slightly chemical scent that lingers on fabrics after drying. For a product marketed as an odor eliminator, the added perfume feels counterproductive—especially for households with scent-sensitive family members or pets. If you’re sensitive to fragrances, this might be a dealbreaker.
Also, don’t expect it to work miracles on carpet or upholstery. This is a laundry product. For accidents that happen outside the washing machine, you’ll still need a dedicated enzyme spray. Several reviewers note this limitation, and it’s a fair criticism.
Who should buy this
- Pet owners with dogs or cats that have accidents, particularly senior pets with incontinence issues
- Parents dealing with baby spit-up, diaper leaks, and mystery stains on kids’ clothes
- Athletes or gym-goers whose workout gear retains odor despite regular washing
- Households with multiple pets where bedding and blankets need frequent deep cleaning
Skip it if you require fragrance-free products or if your stain problems are primarily on carpets and furniture rather than machine-washable fabrics.
FAQ
Does it work in cold water? Yes, but enzymes perform better in warm water. For best results on tough stains, wash in warm or hot water when the fabric allows.
Can I use it with any detergent? Yes, it’s compatible with both liquid and powder detergents, including HE formulas.
Is it safe for septic systems? The enzyme-based formula is septic-safe and biodegradable.
The Verdict
Buy it if you’re fighting persistent pet odors or biological stains that survive regular washing. It’s a legitimate solution, not a marketing gimmick.
Skip it if you need fragrance-free products or your laundry issues are limited to everyday dirt and sweat.
Rating: 4.6/5
It earns the high score because it actually solves a problem most detergents can’t—but the added fragrance keeps it from being perfect.
