Pet Urine on Hardwood Floors, Any Solution?

[Garrett Hogan]

I will be closing on a property next week that was previously a rental for the past 8 years. The apartment smells horrible due to the tenant allowing her pets to urinate all over the place. Their was carpeting on top of the hardwood floors that has been ripped out, but the smell has not gone away. 

The floors themselves are in pretty good condition with the exception of a few spots which we planned to removae and patch. I would love to just be able to sand, stain and refinish the hardwood floors, but Im concerned that the smell won't go away. 

Ive looked into enzyme cleaners, and other chemicals, but havent found anything suitable for floors. 

Does anyone have any experience dealing with this sort of issue? What was the solution.

We had a back bedroom of a 3/2  ranch with the same problem.  We sanded the urine spots with a hand sander and applied BIN Shellac Base Primer (White) on the entire floor.  It took 3 coats before the smell was gone.   We put carpeting down in all 3 bedrooms.  No smell.  There was no chance of saving the hardwood floor.  I hope this helps, and good luck.  I know what you're going through!
