Before using the cat urine remover, try to absorb as much urine as possible with paper towels. If the cat has soiled the carpet or a leather sofa, first check whether the cat urine remover is suitable for use on that particular surface. Apply a generous amount of the odour remover to the affected areas and then just let it dry. The enzymes and microorganisms will do the cleaning on their own. If the urine has gotten very deep into the material, for optimal results you may have to use the cat urine remover several times. Treat any urine stains in the usual way, once the product has achieved its full effect. You can buy cat urine remover and other cleaning agents from well-known manufacturers such as Simple Solution, Trixie and many others.
