Commercial pet odor neutralizers get rid of urine odor and neutralize the smell. They are available at pet stores and most grocery stores but should be tested on a small area before regular use.
Neutralizing products do little good unless all traces of old cleansers are removed from the area being treated, according to the Humane Society. Nonprotein-based cleaners weaken the neutralizing effects of enzymatic products because they use up their cleaning power on the old products that were left behind on the area. Baking soda is also effective in neutralizing urine odor, according to Arm & Hammer, as is white vinegar. While the smell of vinegar may be pervasive at first, it quickly dissipates, leaving behind a clean, fresh scent.
