Urine Off from Bio-Pro Research “guarantees to completely eliminate all traces of pet and human urine from any surface,” the company said.

“Most products use detergents, surfactants, fragrances, alcohol, or hydrogen peroxide to simply mask the odor. Some even use chemicals that encapsulate the urine molecules and temporarily seal in the odor,” said Bill Hadley, CEO of Bio-Pro Research. “The problem is these are only temporary. Any type of moisture will reactivate those remaining uric acid crystals and the smell returns just as strong.”
