Pet urine smell in hardwood floors

[Beth Wheeler]

I am working on a home that has a horrible pet urine smell. We pulled the carpets out of the home and found hardwood floors. However, the smell of pet urine is extremely bad and the floors have been saturated.  How do I get the pet urine smell out of the hardwood floors?  I would love to save the floors, but I would settle for getting the smell out.
