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.

Quote from @Chris Ayars:

Not sure about wood, but white vinegar gets the urine smell out of a lot of things. Wood flooring may just have to be replaced if the urine has saturated deeper than floor refinishing will handle.

 I ran into a hardwood flooring specialist in the hardware store and asked him about the pet urine. He suggested spraying enzyme remover and/or 50/50 mix of white vinegar and water.  He said once you spray it on the floor to put kitty little on top and walk all over it crushing the kitty litter into finer particles. Leave it on for at least an hour and then remove. Repeat if needed.  We tried this and it worked tremendously. We are applying for the second time now, but there is just a slight odor at this point.  I may be able to save these floor after all.  I am so impressed!
