I bought a house a few years ago and the sellers must have had a dog with a really bad problem, the house stank to high heaven from pee-spots all over the floor including one spot that we called “Ground-Zero”. We tried every product on the market including a well-advertized urine-odor remover and Kilz. Nothing removed the odor except my Skill Saw. After trying for a month to get the smell out I had to remove part of the the floor down to the sub-flooring, then clean and seal the subflooring. I found that the doggy-pee had soaked through the carpet, between the cracks in the boards all the way down to the sub-floor. However, we got the stink out of all of the dog’s other favorite poddy-spots. We cleaned them with regular houshold cleaners then sealed it over with Kilz. The moral of the story I guess is that if it is REALLY bad you may have to simply remove the offending materials.
