We tried both the Capture and the Planet Urine brand. Both cleaned our carpet and left it smelling fresh and looking bright without steaming or soaking the carpet. The yellowness of the urine stains were removed along with the odor. Unfortunate under black light we were still left with a white glow where the stain was. There are several organic and enzymatic products on the market today that remove both the stain and odor.
All urine is an organic material.
That is why inorganic chemicals and perfumes will not remove the stain or the odor. It works on pet stains, urine, blood, grease, ink, shoe polish, wine, etc. Old stains should be sprayed and allowed to stand for 60 seconds, then blotted up with a paper towel or cloth. When using enzymatic products, make sure to use freshly diluted enzymes. Let the solution soak in as deeply as the urine has penetrated, and keep the area warm and wet for 24 hours.
