There are several enzymatic-type products that will neutralize organic (pee, vomit, etc.) messes. You can find them most often in the pet department of places like Wal-Mart or even your local grocery store.
I use "Out!" which is fairly cheap, can be bought at both of the above mentioned places (at least where I live) and has a pleasant smell that isn't too strong.
If there is a stain, that will take more work, and I can't help you there. I have the same problem.
