If shampooing the carpet has made the urine smell worse, it's possible that the cleaning process has spread the urine deeper into the carpet fibers or the underlying padding. Here are some steps you can take to help eliminate the smell:
Blot the area: Start by blotting the affected area with clean, absorbent towels or paper towels. Apply gentle pressure to soak up as much liquid as possible. Avoid rubbing, as it can spread the urine and push it deeper into the carpet.
Use an enzymatic cleaner: Enzymatic cleaners are specifically designed to break down the organic compounds in urine. Look for a pet stain and odor remover that contains enzymes. Follow the instructions on the product and apply it generously to the affected area. Allow the cleaner to sit for the recommended amount of time to allow the enzymes to work.
Rinse with water: After the enzymatic cleaner has had time to work, rinse the area thoroughly with clean water. You can use a spray bottle or a clean cloth dampened with water. Blot the area again to remove excess moisture.
Baking soda and vinegar: If the smell persists, you can try a combination of baking soda and vinegar. Sprinkle baking soda generously over the affected area and then spray or lightly pour vinegar on top. The mixture will create a fizzing reaction. Allow it to sit for a few hours or overnight, and then vacuum the area thoroughly.
Steam clean: If the odor still lingers, you may need to use a steam cleaner to deep clean the carpet. Steam cleaning can help remove deep-seated odors and stains. Follow the manufacturer's instructions for operating the steam cleaner and use a cleaning solution specifically designed for carpets.
Professional cleaning: If the smell persists despite your efforts, it may be best to seek professional carpet cleaning services. Professional cleaners have specialized equipment and expertise to effectively remove stubborn odors.
Remember, it's crucial to address urine odors promptly because if left untreated, they can permeate the carpet and even the subfloor, making them more challenging to eliminate.
