Remove dog urine from carpets?Does anyone know of a good product I can use with my steamcleaner?

I did wash the stains out and I rinsed my carpet with distilled vinegar. However, I want to get rid of all of the smell--can anyone tell me of a product that I can use in my steamcleaner? I can't really see dog urine stains(legally blind)and so I need something that can be done with my machine. Any recommendations? Thank you in advance
