Dog pee smell - stained hardwood floors

[Kat Rathell]

We asked our tenants to move out due to the blatant violation of the 'no pet' clause, but the damage has been done, and the unit reeks of dog pee. The floors are dark, so we have no idea as to the source, and it has been a few months. 
Has anyone been successful at eliminating the dog pee smell from hardwood floors where you had to treat the entire floor (2-3 rooms)? How did you accomplish that? Is that something you can deduct from the deposit, and if so, can you only deduct supplies, or also labor if you hire somebody to do it?

It really sucks because it was a newly rehabbed unit, they were only our 2nd tenant and the floors were in fantastic shape before they moved in :(.

@Kat Rathell - First, all things with security deposit handling depend on the laws in your state and how the matter is spoken to in your lease. For example, my lease states that in the event of a smoking or pet violation, I may then charge a $750 fine in addition to charging the security deposit as needed to cure any effect of the lease violation - such as damage and/or smell. And if the security deposit were not sufficient to cover the damage, I would then go after the tenant(s) for the full amount of the damage.
