Biz has been on the laundry shelf since 1969, but most people who buy it for one stubborn stain end up keeping a box around for everything else. Biz cleaner is a powdered enzyme-based stain remover that works on protein, blood, sweat, food, grass, and pet odors better than almost any liquid product on the market. The reason it underperforms in side-by-side detergent tests but wins on stains is that it is not detergent — it is an enzyme booster designed to be added to your wash, not used alone. This guide covers what Biz actually does, how to use it correctly, and where it beats every other product.
What Biz Actually Is
Biz is a pre-soak and laundry booster containing four classes of enzymes: protease (breaks down protein stains), lipase (fats and oils), amylase (starches), and cellulase (cotton fiber refresh). It also includes oxygen bleach (sodium percarbonate) and surfactants. The combination targets stains that detergent alone cannot lift.
The current formulation is hydrogen peroxide-based, color-safe on most fabrics, and biodegradable. A 4 lb box runs $14 to $20 at most grocery stores and lasts roughly 50 loads when used as a booster, far fewer if used as a pre-soak.
How to Use Biz as a Laundry Booster
Add 1 scoop (about 1/4 cup) of Biz directly into the washer drum at the start of a load, on top of your regular detergent. For HE machines, add it before clothes go in, not into the detergent dispenser. The enzymes activate in warm water and break down stains during the agitation cycle.
Use Biz on every load that contains protein stains: sweaty workout clothes, kid clothes with food, blood-stained sheets, or pet bedding. For everyday laundry without obvious stains, save it. Adding Biz to clean clothes wastes the enzymes.
Pre-Soaking With Biz for Tough Stains
For stains that have set in or fabrics you cannot wash hot, pre-soak in a Biz solution before the regular wash. Mix 1 cup of Biz powder with 1 gallon of warm (not hot) water in a bucket or laundry tub. Submerge the stained item completely and let it soak 30 minutes to 6 hours.
The enzyme activity peaks at 90 to 110°F. Hotter water (above 130°F) denatures the proteases and reduces effectiveness. After soaking, wash normally with detergent. The pre-soak alone removes 70 to 80 percent of the stain before the wash even starts.
Stains Where Biz Outperforms
Biz is the right tool for protein-based stains because of the protease enzymes. Blood, sweat, breast milk, baby formula, vomit, urine, and grass all qualify. For these stains, Biz beats OxiClean, Tide pods, and Shout side by side because OxiClean is mostly oxygen bleach without the targeted enzymes.
Pet stains on washable items respond especially well. Cat urine on a dog bed cover comes out completely after a 4-hour Biz soak followed by a normal wash with All Free Clear. Try the same with OxiClean and the urine smell often returns when the bedding gets wet again.
Stains Where Biz Underperforms
Tannin stains — red wine, coffee, tea, dark berries — are the weakness. The enzymes do not break down tannins; oxygen bleach does part of the job but not all. For tannin stains, use a dedicated tannin remover like Wine Away or a chlorine-bleach-safe approach if the fabric allows.
Oil-based stains (motor oil, lipstick, salad dressing) sit between Biz’s strengths and weaknesses. Lipase enzymes help, but a degreasing pretreatment like Dawn dish soap on the stain before the Biz soak gets a better result.
Beyond Laundry: Other Uses for Biz
Biz works well outside the laundry room. A 1/2 cup in 1 gallon of warm water cleans organic stains on grout, ceramic tile, and sealed concrete. Apply with a stiff brush, let sit 10 minutes, scrub, rinse. Pet urine on tile grout responds especially well.
For carpet spot-cleaning, dissolve 1 tablespoon of Biz in 1 cup of warm water, apply to the stain with a clean cloth, blot — do not rub — let sit 30 minutes, then blot again with clean water. Test on a hidden corner first; some carpet dyes can lighten with the oxygen bleach component.
What Surfaces to Avoid
Biz is not safe on wool, silk, or leather. The proteases attack the protein structure of these natural fibers. Stick to cotton, polyester, nylon, and cotton-poly blends. Read garment labels — anything dry-clean-only should not see Biz.
Avoid using Biz on metallic-trimmed clothing or items with glued embellishments. The oxygen bleach can dull metallic threads and the enzymes can weaken adhesives. For these items, hand-wash with a mild detergent only.
Cost Per Use Compared
A 4 lb box of Biz at $16 contains roughly 64 booster doses or 12 to 16 pre-soak treatments. Cost per booster load is $0.25; cost per pre-soak is around $1. For comparison, OxiClean Versatile Stain Remover runs $0.18 per scoop, Shout Trigger costs $0.15 per stain, and a Tide Pod is $0.30 per load.
Biz is competitive on price for what it does, especially when you consider how often it eliminates the need for a second wash cycle on stained items. Save a single 30 percent of energy and water by getting the stain out the first pass and the box pays for itself in a few months.
Storage and Shelf Life
Keep Biz powder in its original container with the lid sealed in a dry cabinet. Humidity activates the oxygen bleach and reduces enzyme activity. Stored properly, an unopened box stays effective for 2 years; an opened box for 12 to 18 months.
If the powder cakes or smells faintly chlorine-like, it has degraded — toss it. Fresh Biz powder is a uniform pale blue-green and pours freely.
When to Pick Biz vs. Alternatives
Use Biz when you have protein stains, when pet odors persist after washing, when towels and athletic wear need a refresh, and as a periodic booster for white linens that have yellowed. Use OxiClean instead for general brightening and tannin stain assist. Use chlorine bleach (when fabric allows) for white cotton and linen with stubborn yellowing.
Have a small stash of all three in the laundry room. Each one wins different categories of stain, and the combined cost runs under $50 a year while saving you from replacing stained items prematurely.
