My cat had sprayed the brick in my foyer, plus some furniture with detailed carving. I had cleaned it all with other products, but my (neutered) cat kept respraying because the scent was still there. (I know...the ideal would be to work out his territorial issues, but that's another story.) Anyway, this product works. It gets into all the nooks and crannies and eats up the urine and smell. I just left it on the brick, but did wipe it off the furniture after a few minutes. It cleaned it all beautifully without damaging the finish. So far, he's not resprayed!
I absolutely love this product. Some other urine removing liquids might work better on smooth surface but don't do the job when it comes to uneven surface with pores and grooves. I can still smell urine after using other products. With my dog son getting into a funny habit of rushing into bathroom at 3am every day for poos and pees, I wouldn't risk leaving the urine there till I get up as it will all be sucked into the floor pores. This product is excellent as I find no trace of smell in my floor. Highly recommend.
