It neutralizes the odor molecule instead of perfuming over it

Sprays and plug-ins add a stronger scent on top. The odor molecule is still in the carpet fibres, so you smell perfume plus dog for an hour, then just dog again by day three.

K.O.E. is not a mask and not an enzyme. It bonds with the compounds producing the smell and neutralizes them. Nothing is left behind to reactivate, so there's nothing to come back.

One 16 oz bottle makes 64 gallons of cleaner

A $15 spray bottle from the pet store lasts about a week of accidents. One K.O.E. bottle makes sixty-four gallons of finished cleaner: enough for a spray bottle, a mop bucket and the car, for months.

The built-in measuring chamber is the measuring cup. Squeeze until the chamber fills to the line, pour into a gallon of water, done. Overfilled? It drains back into the bottle.

  • 7.5 ml per gallon, marked on the bottle
  • Goes straight into a spray-mop reservoir
  • Most customers report one bottle lasting 3+ months

It works everywhere the smell actually lives

Pet odor isn't in one place. It's in the rug, the crate tray, the litter corner grout, the back seat and the hardwood the dog drools on. Because K.O.E. is water-based, the same dilution goes on all of it. It's what clinics, shelters and groomers use on cages, runs, tables and walls.

  • Carpet, rugs, upholstery and bedding
  • Hardwood, tile, leather and crates
  • Litter areas and car interiors

Safe around pets and kids once dry

No bleach, no ammonia, no phthalates, no parabens. K.O.E. is water-based, so once a treated surface is dry your dog can go straight back to the rug and the kids can go straight back to the floor.

  • Non-enzymatic, no harsh fumes while you clean
  • Won't discolour fabric (test a hidden spot first)
  • Keep the concentrate itself out of reach, like any cleaner

Three finishes, zero "cleaning product" smell

The odor work is identical in every bottle. What you choose is what the room smells like for the first hour after: Unscented (the pro original, no fragrance at all), Fresh citrus or soft Apricot.

Then it fades to nothing. A clean room, not a scented one, which is the whole point.

What pet owners are saying

★★★★★

"Crate smell was my white flag. Diluted one chamber, wiped the tray and the cushion, dry in 20 minutes. Unscented smells like a clean house, not a candle."

★★★★★

"The litter corner used to hit you the second you walked in. One pass with Fresh on the floor and around the box and my mother-in-law didn't notice we had cats."

"Hardwood throughout and a bulldog who drools on everything. Goes straight in the spray mop reservoir. One bottle has lasted me three months."

Frequently asked questions

How is this different from an enzyme cleaner?
Enzyme cleaners need time, warmth and moisture to "digest" the odor source and often need repeat applications. K.O.E. is non-enzymatic: it bonds with the odor molecules on contact and neutralizes them, so one treatment is usually enough and it works on hard floors, leather and cars where enzymes struggle.
How do I dilute it?
Squeeze the bottle until the chamber fills to the ¼ oz line (7.5 ml). Pour into a gallon of water and shake. For a litre spray bottle, about 2 ml. One 16 oz bottle makes 64 gallons.
Is it safe around my dog, cat and kids?
Yes. It's water-based with no bleach, ammonia, phthalates or parabens. Let treated surfaces dry before pets settle back on them, and keep the concentrate itself out of reach.
Will it stain carpet or fabric?
It's colourless once diluted and is used on carpet, upholstery and bedding every day. As with any cleaner, test a small hidden spot first for colourfastness.
Which scent should I pick?
Unscented is the pro-grade original vets and shelters use: no fragrance at all, just the odor gone. Fresh reads as "just cleaned", Apricot is soft and sweet. Both scents fade to nothing within an hour or two.
What if it doesn't work for me?
Use the whole bottle. If the odor is still there after 30 days, email us and we'll refund you. No need to send anything back.
How fast does it ship?
Orders leave within 24–48 hours with tracking. Free shipping is included on 2 bottles or more.
Results may vary. K.O.E. is a household cleaning concentrate; keep out of reach of children and pets and test a hidden spot before use. Review statistics reflect verified customer feedback collected by Odorsy. © 2026 Odorsy.
