If you have an older hardwood floor with black spots from pet urine or overwatering, you can address this issue using an enzyme cleaner for pet urine and sanding the affected area if necessary. Follow up with refinishing using a suitable stain and sealant. For stains from overwatering, first resolve the moisture issue, then assess whether sanding or replacing the boards is needed. Consider consulting a professional for accurate floor repair services.
