I just moved into an old farmhouse that has been in our family for years. It has all natural very pretty and in good condition wood floors; however, the person that lived here for a year before I did, had cats that urinated on the carpets in two of the bedrooms. I started by ripping out the carpet, and the wood floor underneath was saturated at one point also. Is there ANY way to get it out? I've tried mopping it and spraying numereous coats of pet stain and deoderizer on it, and I can still smell it!!!! Wondering if Amonia will ruin the floor, and any other suggestions would be WONDERFUL!!!!
