My name is Vicki and I tried the product Devour Plus. I had a rental home. The renters used one of the rooms for their dog. The urine odor was so strong that I couldn’t go near that room. I tried everything to get the smell out, including tearing out the flooring. The smell was in the concrete, I finally got some Devour Plus and it worked. The odor is gone. Thank you Grawood Enterprises.
