Zero Odor Pet Odor Eliminator - Air Cleaner, Purifier & Deodorizer - More Than an Air Freshener - Actually Eliminates Odors at a Molecular Level - Refill (64 Ounces)

I don’t usually write reviews but felt this product was so good I must. We had an issue with cat urine on our sofa after she got shut in the lounge. Having resorted previously to throwing a perfectly good sofa away due to not being able to get rid of the smell, I thought I would try this and I cannot recommend it enough. The smell of the cat urine was much reduced with one application and has completely gone with a second. It has also got rid of the pungent smell of some other treatment I tried first. It has left a slightly chorine/ bleach smell which is very light and just smells ‘clean’ and can only be smelt close up. There is no staining or marking of the sofa fabric. I had not realised when I bought this that it is a refill for the smaller spray version and so I decanted some into an empty rinsed out spray bottle from another kitchen cleaner which I labelled. Overall I would highly recommend this and although it is a little expensive it is worth the money as my alternate was going to be a new sofa! Had I realised I could have got away with the smaller spray bottle, but I will use this for items such as shoes.

I’ve been very stressed about my elderly cats leaky bladder, as is she. I was very apprehensive on buying due to the price (I bought the $75 size, I believe a gallon?) since she leaks every night and evening when she gets too lazy to go to the washroom, I would be using it everyday, the $30 spray bottle size would last me a week. So I had to buy bigger. I loaded up a spray bottle as soon as I could and sprayed any known pee marks. It works instantly… it’s a bleach smell, but it’ll disappear. I would rather that scent than cat pee! Or fragrance mixed with pee. The worst. I’m actually quite relieved that I found a product like this.

Expensive, but you get what you pay for with this product. It works very well, but it's not instant, you need to clean the soiled area thoroughly and then apply the product liberally.

Very good at getting rid of smells

Update: it has been a handful of years since I purchased this product and have completely forgotten about it. However, re-looking into it since inconstency occurred (the past year) and one of the spots I treated with this was revisited by the cat. I may not have treated it enough times when I did use this product, but as stated below - star knocked off. Will update if I do decide to repurchase and try it again knowing more about cleaning up urine. I have been searching for a product that would dissolve urine smells for at least a year! I have an elderly cat with a VERY sensitive nose. I have put so many different products in the carpet to attempt to get rid of the smell. I won't list them all here because I have tried a laundry list of items with no resolve-until this product. I bought this product because majority of the reviews were good on it. Below is what I did in hopes that it helps someone else with urine issues. I vacuumed a section of the carpet and then shampood it thoroughly using hot water (yes, it was that bad). Then, I sprayed this stuff generously onto the carpet. Next, I took a utility brush and scrubbed the product into the carpet. I let it sit for a few hours while finding my black light (UV) to check for urine stains. I checked the area I knew should have showed up very clearly with the light. Behold - the UV light showed a faint marking (which it would have glowed bright before)! I sprayed the areas again generously that were still showing up to help reduce the spots and let the carpet dry out. Throughout the time I was waiting for the carpet to dry, I was smelling my carpet. I am sensitive to the smell as well (hence why I tried a lot of products), so I knew if I could faintly smell it, my cat could too. I did notice that the UV light will not show up long before the Odor is gone. It's been roughly 48 hours since I cleaned the worst section and here are the results: - it mostly passes the UV light test, which is impressive for the first round of a product that actually works. - the Odor smell is mostly gone - the scent left behind is kind of a chemically one (which a pleasant neutral scent can assist with easing it), which may be from the carpet shampoo that I use. It is not a horrible scent and way better than urine smell. - there was no discoloration on the carpet after using this product. I have given this product a 5 star review at this moment in time. Once the carpet is fully treated and there is no result for smell and UV light test, the final test will be my cat and if she goes potty in the spots (outside of what an elderly cat would). If she does go potty there after completely cleaned, I'll knock a single star off only because of my cat's nose. I'll still use this product, but part of the review will be from the pet too.
