How to clean dried dog poo off floor?
My wife's elderly grandfather has two dogs. He has dementia and its progressing to the point where he no longer understands how to properly care for these dogs, or himself for that matter. He doesn't let them out to use the bathroom, so they poo all over the floor and then he refuses to clean it up. We are looking into re-homing these dogs because of this whole situation and also finding him a caregiver. His daughter is actually a trained veterinarian. She's handling the situation. But I need to get this floor cleaned. It's all over the place. What I'm looking at has been there for weeks. Its as hard as concrete and basically glued to the floor. After two hours of scraping with a putty knife and using a floor buffing machine with a scrubbing wheel. I've still barley put a dent in this mess. What can I use on this dried on poo? I'm thinking there must be some sort of chemical that can dissolve this stuff and unstick it from the floor. But I don't want the chemicals to damage the hardwood. What should I use? I considered maybe a natural solvent like mineral spirits or something. I'm just not sure what that would do to the hardwood underneath. Any suggestions?
