How can I effectively remove pet urine from carpets?

To effectively remove pet urine from carpets, start by blotting up as much of the urine as possible with paper towels. Then, apply a mixture of water and white vinegar to the affected area and blot again. Next, sprinkle baking soda over the spot and let it sit for a few hours before vacuuming it up. Finally, use a carpet cleaner specifically designed for pet stains to thoroughly clean the area.
