Review on ODORx Un-Duz-It Unleashed Pet Urine Odor and Stain Eliminator - Effective Enzyme Action, 1 Gallon Commercial Formula by Josh Chenier

This chemical eliminates the smell of urine when worn heavily. As another reviewer mentioned, it appears you need to abandon the chemical application. If the chemical is removed, it can be proven that the odor is still there. I've found that small disposable dog pee can be removed and retrieved, but a larger mess requires constant application of the chemical. Plan to buy twice as much as you think you will need. This is possibly the best non-professional chemical to remove urine. For reference, I applied twice to the areas and the exposure time was 1 hour. However, some odor remained in large patches when the chemical was removed.
