Hands down for removing odor this is the best. I have major problems with anything that is scented. With just a few sprays of this I can breath again. Although expensive, this is the best odor eliminator ever!! If this wont take the smell away, nothing will.

Ive been using this product now for almost fifteen years. Im a professional housecleaner and have never found a product so consistently effective on odors as this. It has never failed to handle any odor I have ever used it on, pet, carpet mold, human urine or otherwise. I consider it, through professional experience, the best product of its kind on the market. It has never failed me.

I have 2 elderly cats. One occasionally missed the litter box, and they both have digestive issues and throw up on a regular basis. This product has been a life saver for my carpets. Not only does it eliminate the odor, it does a pretty good job with removing the stains. Not perfect - but better than over the counter carpet cleaners.

This is one product that totally lived up to its advertised claims: 4-8 sprays and within minutes even the worst litter bathroom smells are gone!! AND no cover up smell left behind!! Would fully recommend this product for anyone who does not want to add a smell in order to remove an odor -- and with economical refill bottles, it just does not get much better than this product!!

Works great

One of my cats is a sprayer. Zero Odor gets rid of every last bit of that terrible smell. I also appreciate that it doesnt leave a lingering, cloying scent like some other odor eliminators do. Theres a faint fresh scent when you first spray it, and that dissipates quickly. It works great on cooking smells, bathroom smells, freshening clothes, you name it. My household will never, ever, ever be without Zero Odor.

This stuff is amazing. I bought 2gallons for my b&b and my home I’m selling. I have four dogs who just smell “Doggie”,like hounds can. So I spray the rugs down - that they lie on- put the fans on and shut the doors. In an hour I go back in and no doggie smell! Just clean scent free house to show.

Zero Odor is great! Odors disappear and theres no masking scent left behind. Everything just smells fresh. Use it to clear the air in the bathroom or kitchen, on bedding, upholstered furniture, in garbage cans, pet areas....anywhere theres an odor or its just musty. And, its made in the USA.

This product works great, especially on pet odors. I spray our carpets regularly to avoid having to get them professionally cleaned all the time.

Love this product. Have tried many, and nothing else compares. Our indoor/outdoor cat had several accidents outside her cat box while we were gone for the weekend. I had cleaned the spots but the odor of Kittie diarrhea wouldnt go away. Used vinegar and that killed the remaining csy smell, but the vinegar smell was overpowering. Took 3 treatments but the smell is gone. Thank you Zero Odor!!
