David Sweeny alludes to the probable problem Lonny is having.
For any deodorizer to work you need to know/do two things.
1. Remove the source by cleaning, or scrapping what can't be cleaned practically.
2. Any Deodorizer that actually neutralizes has to physically contact any and all odorous residue to function.
On urine, you have to remove the source contaminant with proper preconditioning and extraction, just like David describes.
That which can't be removed has to be either scrapped, or in the case of concrete/wood it has to be sealed after cleaning.
It is impractical to remove source contamination on padding. If padding is contaminated, there is little in the way of options but to replace. Some will indicate that you can supersaturate a pad with something like an ultra concentrated sanitizer, but IMHO, you don't want to leave that much chemical residue behind.
Deodorizer is something you only want to apply to a post-cleaning residue. This means that the deodorizer has much less physical contamination to overcome, as well as everyone's peace of mind that the urine is actually gone, for the most part. There are one-step products that remove odor and staining, such as Pet Zone with Hydrocide, but still a thorough extraction with a good urine-specific preconditioner is the preferred first step.
