To effectively remove human urine smell from a leather couch, a multi-step approach is required to both clean the surface and neutralize the odor at its source. Based on user experiences, the most recommended solution is an enzymatic cleaner, which is specifically formulated to break down the uric acid crystals in urine that cause the lingering smell.
First, if the accident is fresh, immediately blot the area with a clean, dry cloth to absorb as much liquid as possible. Do not rub, as this can spread the urine and push it deeper into the leather.
Next, select an enzymatic cleaner designed for use on leather. Before applying it to the stain, always test the product on a small, inconspicuous area of the couch to ensure it doesn't cause discoloration. Once you have confirmed it is safe, apply the cleaner to the affected area according to the product's directions. This usually involves saturating the spot so the cleaner can penetrate as deeply as the urine did. It's crucial to address the source of the smell, which may have seeped into the cushion's foam or stuffing. If possible, unzip the cushion cover and treat the interior foam with the enzymatic cleaner as well, allowing it to air dry completely.
After the enzymatic cleaner has worked and the area is fully dry, the final step is to condition the leather. Use a high-quality leather cleaner followed by a leather conditioner. This will restore moisture to the material, preventing it from drying out or cracking after the cleaning treatment and helping to maintain the integrity of your couch.
