How can I effectively remove pet urine out of carpet?

To effectively remove pet urine from carpet, start by blotting up as much of the urine as possible with paper towels. Then, mix a solution of equal parts water and white vinegar and apply it to the affected area. Let it sit for a few minutes before blotting it up with more paper towels. Finally, sprinkle baking soda over the area and let it sit for a few hours before vacuuming it up. Repeat these steps as needed until the odor is gone.
