My husband and I have tried everything… We recently purchased a fixer upper home.   Beautiful hardwood floors throughout, the problem it’s that the previous owner had a room where dogs were kept.  The room smells awful from urine.  We have scrubbed the floors, used baking soda and even tried a Urine destroyer.  Nothing has worked.   We are going to be sanding the floors as they are in rough shape…any other ideas to be the smell out? Thank you!!
