works best. I have 4 cats and that is the best thing for fresh urine. Also, cats do not like the scent of orange for some reason. You might try putting an orange air freshener in your car to avoid any other unwanted sprays. I have also had really good luck cleaning it with nothing more than warm water, a drop of washing-up liquid, and a few drops of either orange oil or lavender oil added - wipe down the seat back and squeezing the rope magazine rack between the almost dry rag several times. Lavender oil is not only a deodorizer but a natural disinfectant.

If the odor still persists, sprinkling baking soda and salt on the DRY carpet under the seat back, rub it in, and letting it sit for several hours/overnight and then vacuuming up will take care of any pee that may have dripped down or soaked through.
