So this s how the story goes..... (please help me solve the ending)? - how to remove dog pee from marble

So, my 8 1 / 2 weeks old Chihuahua "happiness" (my mother called him) was out of his cage, as my parents worked in the dining room. Well, have to go pee really bad luck, but he forgot that the platform is to urinate, so he decides to pee on the marble floor so my parents can clean it. Well, big mistake! My parents were super tired and decided to go to bed, when he brought the dog.

The next day came and I woke up to take the dog to go pee. I came back and ate lunch. My eyes began to wander around and I saw the pee yellow spot on the floor! I immediately piss clean for the difficult task, but the pee stain the marble floor! It is a kind of a leak, and now the ground is obscured by the piss! Is there a way out of the marble floor of my father?

I did this happen before for owners of dogs? How clean?
