To remove pet urine smell from carpet, start by pressing a clean, dry cloth or paper towel onto the area to absorb as much urine as possible. Avoid scrubbing, since that can spread the urine and push it deeper into the carpet fibers and padding. Urine odor can linger because urine can soak below the surface and leave behind organic residue and odor-causing compounds that continue to smell even after the carpet feels dry. That’s why a bio-enzyme cleaner can be especially useful. The enzymes help break down the source of the odor instead of simply masking the smell with fragrance. 

RUFF STUFF Bio-Enzyme Stain & Odor Eliminator by Lillian Ruff is designed to target organic, protein-based, and fat-based pet messes, including urine, feces, vomit, saliva, food spills, and odors. Since carpets and dyes can vary, test on a hidden area first, allow the cleaner time to work as directed, and blot away any excess product.
